Water Supply Facilities Work Plans
1.0 INTRODUCTION
The purpose of the City of Miami Water Supply Facilities Work Plan (Work Plan) is to identify and plan
for the water supply sources and facilities needed to serve existing and new development within the
City's jurisdiction. Chapter 163, Part II, F.S., requires local governments to prepare and adopt Work
Plans into their comprehensive plans within 18 months after the water management district approves a
regional water supply plan or its update. The Lower East Coast Water Supply Plan Update was
approved by the South Florida Water Management District (SFWMD) on February 15, 2007.
The City of Miami has recognized the importance of water conservation through the Miami
Comprehensive Neighborhood Plan (MCNP). The City recognizes that in order to maintain a proactive
water conservation program there has to be an effective coordination program with Miami -Dade County
Water and Sewer Department (MDWASD) to ensure the success of the program. In addition, the City
maintains an excellent working relationship with WASD as a retail customer to ensure compliance with
all applicable regulations and guidelines.
Residents of the City of Miami obtain their water directly from the Miami -Dade County Water and
Sewer Department (WASD), which is responsible for ensuring that enough capacity is available for
existing and future customers. Under this arrangement, the City will coordinates with WASD to ensure
that enough capacity is available for existing and future customers and supporting infrastructure.
The City of Miami Water Supply Facilities Work Plan (Work Plan) will reference the initiatives already
identified in Miami -Dade County's 20 -year Work Plan since the City is a retail buyer. According to state
guidelines, the Work Plan and the comprehensive plan amendment must address the development of
traditional and alternative water supplies, bulk sales agreements and conservation and reuse programs
that are necessary to serve existing and new development for at least a 10 -year planning period. The
City of Miami Work Plan will have the same planning time schedule as Miami -Dade County's 20 -year
Work Plan.
The City of Miami 20 -year Work Plan will adopt the same planning time schedule as the first twenty
years of the Miami -Dade County's Water Supply Facilities Work Plan
The City's Work Plan is divided into five sections:
Section 1 — Introduction
Section 2 — Background Information
Section 3 — Data and Analysis
Section 4 — Work Plan Projects/Capital Improvement Element/Schedule
Section 5 — Goals, Objectives, Policies
1.1 Statutory History
The Florida Legislature has enacted bills in the 2002, 2004, and 2005 sessions to address the state's
water supply needs. These bills, especially Senate Bills 360 and 444 (2005 legislative session),
significantly changed Chapter 163 and 373 Florida Statutes (F.S.) by strengthening the statutory links
between the regional water supply plans prepared by the water management districts and the
April, 2010

City of Miami
Water Supply Facilities Work Plans
comprehensive plans prepared by local governments. In addition, these bills established the basis for
improving coordination between the local land use planning and water supply planning.
1.2 Statutory Requirements
Each local government must comply with the following requirements:
Coordinate appropriate aspects of its comprehensive plan with the appropriate water
management district's regional water supply plan, [163.3177(4)(x), F.S.]
Ensure that its future land use plan is based upon availability of adequate water supplies and
public facilities and services [s. 163.3177(6)(a), F.S., effective July 1, 2005]. Data and analysis
demonstrating that adequate water supplies and associated public facilities will be available to
meet projected growth demands must accompany all proposed Future Land Use Map
amendments submitted to the Department for review. The submitted package must also
include an amendment to the Capital Improvements Element, if necessary, to demonstrate that
adequate public facilities will be available to serve the proposed Future Land Use Map
modification.
Ensure that adequate water supplies and facilities area available to serve new development no
later than the date on which the local government anticipates issuing a certificate of occupancy
and consult with the applicable water supplier prior to approving building permit, to determine
whether adequate water supplies will be available to serve the development by the anticipated
issuance date of the certificate of occupancy [s.163.3180 (2)(a), F.S., effective July 1, 2005].
This "water supply concurrency" is now in effect, and local governments should be complying
with the requirement for all new development proposals. In addition, local governments should
update their comprehensive plans and land development regulations to address these
statutory requirements.
4. For local governments subject to a regional water supply plan, revise the General Sanitary
Sewer, Solid Waste, Drainage, Potable Water, and Natural Groundwater Aquifer Recharge
Element (the "Infrastructure Element"), within 18 months after the water management district
approves an updated regional water supply plan, to:
a. Identify and incorporate the alternative water supply project(s) selected by the local
government from projects identified in the updated regional water supply plan, or the
alternative project proposed by the local government under s. 373.0361(7), F.S. [s.
163.3177(6)(c), F.S.];
b. Identify the traditional and alternative water supply projects, bulk sales agreements,
and the conservation and reuse programs necessary to meet current and future water
use demands within the local government's jurisdiction [s. 163.3177(6)(c), F.S.]; and
Include a water supply facilities work plan for at least a 10 -year planning period for
constructing the public, private, and regional water supply facilities identified in the
element as necessary to serve existing and new development. [s. 163.3177(6)(c),
F.S.] Amendments to incorporate the water supply facilities work plan into the
comprehensive plan are exempt from the twice -a -year amendment limitation. [s.
163.3177(6)(c), F.S.]

Water Supply Facilities Work Plans
5. Revise the Five -Year Schedule of Capital Improvements to include any water supply, reuse,
and conservation projects and programs to be implemented during the five-year period.
6. To the extent necessary to maintain internal consistency after making changes described in
Paragraph 1 through 5 above, revise the Conservation Element to assess projected water
needs and sources for at least a 10 -year planning period, considering the appropriate regional
water supply plan, the applicable District Water Management Plan, as well as applicable
consumptive use permit(s). [s.163.3177 (6)(d), F.S.]
If the established planning period of a comprehensive plan is greater than ten years, the plan
must address the water supply sources necessary to meet and achieve the existing and
projected water use demand for established planning period, considering the appropriate
regional water supply plan. [s.163.3167 (13), F.S.]
7. To the extent necessary to maintain internal consistency after making changes described in
Paragraphs 1 through 5 above, revise the Intergovernmental Coordination Element to ensure
coordination of the comprehensive plan with applicable regional water supply plans and
regional water supply authorities' plans. [s.163.3177(6)(h)1., F.S.]
8. Address in the EAR, the extent to which the local government has implemented the 10 -year
water supply facilities work plan, including the development of alternative water supplies, and
determine whether the identified alternative water supply projects, traditional water supply
projects, bulk sales agreements, and conservation and reuse programs are meeting local
water use demands. [s.163.3191 (2)(1), F.S.]

Water Supply Facilities Work Plans
2.0 BACKGROUND INFORMATION
2.1 Overview
The City of Miami, known as the "Magic City", is located in Southeast Florida, in Miami -Dade County on
the Miami River, between the Florida Everglades and the Atlantic Ocean. The original boundaries of
the City encompassed an area approximately 35 square miles. The City of Miami was incorporated in
1896 and has grown into one of the world's renowned centers where people can work, live and play
while enjoying a high quality of life. The City of Miami, known for its diverse culture and ethnicities, is
the largest municipality in Miami -Dade County.
The City of Miami is substantially built -out. Between 1990 and 2000, the City of Miami population grew
from 358,548 to 362,470, an increase of one percent (1.1%)'. Although the 1995 EAR predicted an
increase in population, in 2005 it was estimated that the City's population has increased to 386,8792
residents based on the 2005 BEBR (Shimberg Center of Affordable Housing Bureau of Economic and
Business Research) population data. By all projections, growth will continue to occur in the region, with
future development potential and population growth limited by the scarcity of vacant and developable
land. Current, estimates of population trends have incorporated the relatively of recent deluge
development and redevelopment of new large scale residential projects. The City's greatest
development potential will occur as mid to high rise redevelopment projects. For these reasons, it is
anticipated the City of Miami will receive a much greater share of the County's population growth.
2.2 Relevant Regional Issues
Regional issues that affect the City of Miami include minimizing pressure on the Everglades
ecosystem. The South Florida Water Management District is the state agency responsible for water
supply in the Lower East Coast planning area which includes the jurisdictional boundaries of the City of
Miami. SFWMD plays a pivotal role in resource protection, through criteria used for Consumptive Use
Permitting. As pressure increased on the Everglades ecosystem resource, the Governing Board
initiated rule making to limit increased allocations dependent on the Everglades system. As a result, the
Regional Water Availability Rule was adopted by the Governing Board on February 15, 2007 as part of
the SFWMD's water use permit program. This reduced reliance on the regional system for future water
supply needs, mandates the development of alternative water supplies, and increasing conservation
and reuse.

3.0 DATA AND ANALYSIS
The intent of the data and analysis section of the Work Plan is to describe the information that local
governments need to provide to state planning and regulatory agencies as part of their proposed
comprehensive plan amendments, particularly those that would change the Future Land Use Map
(FLUM) to increase density and/or intensity. Additionally, population projections should be reviewed for
consistency between the County and South Florida Water Management District's Water Supply Plan.
For the purpose of this report 2008 Miami -Dade County Planning and Zoning Transportation Analysis
Zone (TAZ) population projections will be used to calculate City of Miami projected water demands.
3.1 Population Information
The City's existing and future population figures as shown in Table A are derived from 2008 TAZ.
Between 1990 and 2000, the City of Miami population grew from 358,548 to 362,470, an increase of
one percent (1.1%)3. Although the City's 2005 Evaluation Appraisal Report (EAR) predicted an
increase in population, in 2005 it was estimated that the City's population had increased to 386,8794
residents. By 2010, the City's population is anticipated to increase to 401,287; 2015 to 431,505; 2020
to 461,723; and 2025 to 491,9415 (represents an increase of seven percent over the 2008 population).
By all projections, growth will continue to occur in the region, with future development potential and
population growth limited by the scarcity of vacant and developable land.

3.3 Potable Water Level of Service Standard
The City of Miami adopted and currently maintains a potable water LOS level of 155 gallons per capita
per day which is 17% of the county total demand for water. There is no need to revise the LOS level
that the City has adopted. If future population increases project higher demands, the City will work with
the County and SFWMD to refine projections during the five year updates to the water management
plan and also through the State mandated Evaluation and Appraisal Report process.
3.4 Population and Potable Water Demand Projections by City
Population projections for the City of Miami's service area in five year increments from Year 2008 to
2025 and Year 2030 are shown in Table B. Within the City, the population served by MDWASD is
expected to increase approximately 34.2% from Year 2008 to Year 2030.

Water Supply Plan Update.
The WASD's service area is all portions of Miami -Dade County within the Urban Development
Boundary (UDB), excluding, North Miami Beach, and portions of Homestead, Florida City, and North
Miami's service area. The areas within the Urban Expansion are included in the planning horizon after
2015. The following summarizes Miami -Dade County's Work Plan:
Description of population and water demand projections (Exhibit C 3-1 and 3-2, Water Supply
Service Area, Retail and Wholesale Customers, respectively, by Municipality provides
municipal population projections and projected AADF "Annual Average Daily Flow" finished
water based on 155 gallons per capita per day (gpcd). The population information was derived
from Miami -Dade County Department of Planning and Zoning Transportation Analysis Zone
JAZ) 2004 population data. This subsection also provides a brief discussion of WASD's
conservation and reuse programs.);
The Water Supply Facilities Work Plan details the facilities and proposed alternative water
supply (AWS) projects that are planned in order to meet the water demands through 2027.
These projects are expected to be completed in increments consistent with the projected
growth set forth in the Plan. The AWS projects and annual average daily demand (AADD)
assumes that all current wholesalers will remain in the WASD system through 2027, except for
the City of North Miami Beach. The AWS projects are included in the County's Capital
Improvement Element.
In the 20 -Year Work Plan, the WASD is committed to meet the water demand for the municipalities
within the service area. The City of Miami is served by the Alexander Orr, Jr. sub -area and Hialeah -
Preston sub -area water treatment plants.
Alexander Orr Jr. sub -area is comprised of a high pressure system with two major piping loops. This
sub -area delivers water to nearly all of Miami -Dade County south of Flagler Street to SW 248th Street,
including Virginia Key, Fisher Island, the Village of Key Biscayne and, upon request, to the City of
Homestead, and Florida City. The Alexander Orr, Jr. subarea, water treatment plant is supplied by four
water supply wellfields (Alexander Orr, Jr.- capacity 74.4 MGD; Snapper Creek — capacity 40.0 MGD;
Southwest — capacity 161.16 MGD; and West -32.4 MGD), with a total designed capacity of
approximately 308 MGD. In this subarea, there are also Upper Floridan Aquifer wells at two of the
wellfields (West Wellfiled and the Southwest Wellfield). These wells have a total capacity of 25.20
MGD. WASD anticipates using these wells for storage of fresh Biscayne Aquifer water during the wet
season (when operating water levels in the canal allows) for extraction and use in the dry season. In
order to use the Upper Floridan Aquifer wells, the WASD designed an ultra -violet (UV) light disinfection
system for each ASR site to treat the Biscayne aquifer water before injecting in the Floridan Aquifer.
Hialeah -Preston sub -area is comprised of dedicated low-pressure pipelines, remote storage tanks,
pumping facilities and high pressure systems. This sub -area delivers water to nearly all of Miami -Dade
County north of Flagler Street, including Hialeah, Miami Spings, and other portions of northeastern
Miami -Dade County. The Hialeah -Preston sub -area, water treatment plant is supplied by four water
supply wellfields (Hialeah- capacity 12.5 MGD; John E. Preston — capacity 53.28 MGD; Miami Springs
— capacity 79.30 MGD; and Northwest -149.35 MGD), with a total designed capacity of approximately
295 MGD.

3.6 Conservation
3.6.1 County -wide Issues
The Miami -Dade Water Use Efficiency Plan
Water conservation programs are initiated at the local level, by either municipal water utilities or
regional governments. Currently, WASD is saving substantial amounts of water by implementing all
Best Management Practices (BMPs) included in the 20 -year Water Use Efficiency Plan, which was
approved by the South Florida Water Management District in May 2007. The savings from water
conservation often translate into more potable water available for residential and non-residential use,
capital and operating savings, which allow systems to defer or avoid significant expenditures for water
supply facilities and wastewater facilities.
Water Conservation Plans and Development Codes
Miami -Dade County has developed recommendations for new development that would achieve higher
water use savings than currently required by code. The Board of County Commissioners adopted the
Water Use Efficiency Ordinance 08-14 which created Section 8-31 of the Code of Miami -Dade County
on February 5, 2008, and amended by ordinance on September 2, 2008. In addition, the Landscape
Ordinance, creating Chapter 18A and 18B of the Miami -Dade Code of Ordinances was adopted by the
BCC on May 5, 2009.These water efficiency recommendations represent an additional 30 percent to
the water savings identified in the 20 -year Water Use Efficiency Plan. All future development within the
City will be required to comply with water conservation measures as provided through Chapter 8 —
Building Code, Chapter 32 — Water and Sewer Regulations, and Chapter 18A and 18B — Landscape
Ordinance, of the Miami -Dade County Code of Ordinances, which may be amended from time to time.
The list of recommendations submitted to the BCC and the ordinance relating to water use efficiency
standard are presented in Appendix D of the MDWASD Water Supply Facilities Work Plan and are also
posted in the Miami -Dade Water Conservation Portal.
Per Capita Consumption
Furthermore, the WASD will establish per capita consumption for all municipalities including those in its
retail customer service area. Based on this data, the WASD will work with the municipalities to address
those with higher than average per capita and will target programs for those areas. The County
anticipates that the implementation of the BMPs identified in the 20 -year Water Use Efficiency Plan will
result in an adjusted system wide per capita of 147.82 gpcd by 2027.
3.6.2 Local Government Specific Actions, Programs, Regulations, or Opportunities
The City will coordinate future water conservation efforts with the WASD and the SFWMD to ensure
that proper techniques are applied. In addition, the City will continue to support and expand existing
goals, objectives and policies in the comprehensive plan that promotes water conservation in a cost-
effective and environmentally sensitive manner. The City will continue to actively support the SFWMD
and Miami -Dade County in the implementation of new regulations or programs that are design to
conserve water during the dry season.

3.7 Reuse
3.7.1 Regional and County -wide Issues
State law supports reuse efforts. For the past years, Florida's utilities, local governments, and water
management districts have led the nation in implementing water reuse programs that increase the
quantity of reclaimed water used and public acceptance of reuse programs. Section 373.250(1) F.S.
provides that "water reuse programs designed and operated in compliance with Florida's rules
governing reuse are deemed protective of public health and environmental quality." In addition,
Section 403.064(1), F.S., provides that "reuse is a critical component of meeting the state's existing
and future water supply needs while sustaining natural systems."
The City of Miami supports water reuse initiatives under consideration by both the SFWMD and Miami -
Dade County. The County has committed to implement a total of 170 MGD of water reuse as noted in
the County's 20 -year water use permit. In the 20 -year Work Plan, the County identified a number of
water reuse projects and their respective schedule. According to the Plan, "reuse projects to recharge
the aquifer with highly treated reclaimed water will be in place before additional withdrawals over the
base condition water use are made from the Alexander Orr and South Dade subarea wellfields. In
addition, reuse irrigation projects are anticipated for the North and Central District Wastewater
Treatment Plants. These projects will be implemented in the Cities of North Miami and North Miami
Beach, and are currently under construction for Key Biscayne."
3.7.2 Local Government Specific Actions, Programs, Regulations, or Opportunities
The City will support the SFWMD and Miami -Dade County water reuse projects, and implementation of
new regulations or programs designed to increase the volume of reclaimed water used and public
acceptance of reclaimed water.

4.0 CAPITAL IMPROVEMENTS
Work Plan
The City is within Miami -Dade County WASD service area which provides potable water and sanitary
sewer services. As discussed the potable water and sanitary sewer systems have adequate capacity to
meet the needs of current and future residents. At this time the City of Miami has no water facility
projects planned. This section details water supply facilities that are planned within the County in order
for the City of Miami to meet MDWASD's water demands through 2030.
4.1 Alternative Water Supply Projects
Proposed alternative water supply (AWS) projects are to meet MDWASD's increase water demands
through 2030, which encompasses the proposed 20 -year Consumptive Use Permit period. AWS
projects have been identified to meet water demands in the MDWASD service area and may be found
in the 2009/2010 Miami -Dade County Schedule of Capital Improvements(Table 8 and 12 of Appendix
A), the 20 -Year Water Supply Facilities Work Plan and Alternative Water Supply and Wastewater
Reuse Projects Table (Table 1 of Appendix A).
4.2 Capital Improvements ElemenVSchedule
As demonstrated in the previous sections, the Alternative Water Supply Plan being proposed by the
County should meet the increased water demands through 2030. As a confirmation that the County is
committed to fund these projects, the projects for the 20 -Year Work Plan may be found in the
2009/2010 Miami -Dade County Schedule of Capital Improvements (Table 8 and 12 of Appendix A) and
with the 20 -Year Water Supply Facilities Work Plan.

Section 1
Introduction
Miami -Dade County (County) is continuing to experience growth, as it has over the
last 2 decades. The Miami -Dade Water and Sewer Department (MDWASD) provides
drinking water to approximately two million customers in the County. Because of
rapid population growth, complex environmental issues and developing regulatory
and statutory requirements, MDWASD is developing a comprehensive 20 -year plan
for water supply development.
1.1 Background
In response to the finding that traditional water supply sources will not be sufficient
to meet demands of the growing population, of industries and of the environment, the
Florida Legislature enacted bills in 2002, 2004 and 2005. These bills, Senate Bills 360
and 444, significantly changed Chapters 163 Intergovernmental Programs and 373
Water Resources, Florida Statute (F.S.), to improve the coordination of water supply
and land use planning by strengthening the statutory requirements linking regional
water supply plans prepared by the water management districts and the
comprehensive plans prepared by local governments.
The current statutory provisions direct local governments to do the following with
regard to water supply:
1. Coordinate appropriate aspects of its comprehensive plan with the appropriate
water management district's regional water supply plan. [s. 163.3177(4)(a), F.S.]
2. Ensure that its future land use plan is based upon the availability of adequate
water supplies and public facilities and services. [s. 163.3177(6) (a), F.S., effective
July 1, 2005.] Data and analysis demonstrating that adequate water supplies and
associated public facilities will be available to meet projected growth demands
must accompany all proposed Future Land Use Map amendments submitted to
the Department of Community Affairs for review. The submitted package must
also include an amendment to the Capital Improvements Element, if necessary, to
demonstrate that adequate public facilities will be available to serve the proposed
Future Land Use Map modification.
3. Ensure that adequate water supplies and facilities are available to serve new
development no later than the date on which the local government anticipates
issuing a certificate of occupancy and consult with the applicable water supplier
prior to approving a building permit, to determine whether adequate water
supplies will be available to serve the development by the anticipated issuance
date of the certificate of occupancy. [s. 163.3180(2)(a), F.S., effective July 1, 2005.]
Local governments should update their comprehensive plans and land
development regulations as soon as possible to address this water supply
concurrency requirement.
4. Revise the General Sanitary Sewer, Solid Waste, Drainage, Potable Water, and
Natural Groundwater Aquifer Recharge Element (hereafter the "Infrastructure
Element"), within 18 months after the water management district approves an
updated regional water supply plan, to:

Water Facilities Work Plan
Introduction
a. Identify and incorporate the alternative water supply project(s) selected by the
local government from projects identified in the updated regional water
supply plan, or the alternative project proposed by the local government
under s. 373.0361(7), F.S. [s. 163.3177(6)(c), F.S.];
b. Identify the traditional and alternative water supply projects and the
conservation and reuse programs necessary to meet current and future water
use demands within the local government's jurisdiction [s. 163.3177(6)(c), F.S.];
and
c. Include a water supply facilities work plan for at least a 10 -year planning
period for construction of public, private, and regional water supply facilities,
which are identified in the element as necessary to serve existing and new
development. [s. 163.3177(6) (c), F.S.] Amendments to incorporate the water
supply facilities work plan into the comprehensive plan are exempt from the
twice -a -year amendment limitation. [s. 163.3177(6)(c), F.S.]
5. To the extent necessary to maintain internal consistency after making changes
described in Paragraphs 1 through 4 above, revise the Conservation Element to
assess projected water needs and sources for at least a 10 -year planning period,
considering the appropriate regional water supply plan(s) or, in the absence of an
approved regional water supply plan, the applicable District Water Management
Plan. [s.163.3177(6)(d), F.S.] If the established planning period of a comprehensive
plan is greater than ten years, the plan must address the water supply sources
necessary to meet and achieve the existing and projected water use demand for the
established planning period, considering the appropriate regional water supply plan.
[s. 163.3167(13), F.S.]
6. To the extent necessary to maintain internal consistency after making changes
described in Paragraphs 1 through 4 above, revise the Intergovernmental
Coordination Element to ensure coordination of the comprehensive plan with
applicable regional water supply plans and regional water supply authorities'
plans. [s. 163.3177(6)(h)1., F.S.]
7. Address in its Evaluation and Appraisal Report (EAR) the extent to which the
local government has implemented the 10 -year water supply facilities work plan,
including the development of alternative water supplies, and determine whether
the identified alternative water supply projects, traditional water supply projects,
and conservation and reuse programs are meeting local water use demands.
[s.163.3191(2)(1), F.S.]
This Water Supply Facilities Work Plan is meant to satisfy portions of the above
statutory requirements (other portions will be satisfied elsewhere by MDWASD) and,
as stated in Item 1 above, to coordinate with the Lower East Coast (LEC) regional
water supply plan. The LEC Plan was adopted on February 15, 2007 by the South
Florida Water Management District (SFWMD).
1.2 Purpose and Objectives
The purpose of this Water Supply Facilities Work Plan is to present MDWASD's
water supply systems and to provide a plan for implementing water supply facilities,

Water Facilities Work Plan
Introduction
including the development of Alternative Water Supplies necessary to serve existing
and new development. The information contained within this Work Plan will be
included in an amendment to various elements of the County's Comprehensive Plan.
This Work Plan is to be coordinated and updated every five years within 18 months
after February 15, 2007, the date LEC regional water supply plan was adopted.
This Water Supply Facilities Work Plan includes the following primary sections:
■ Section 2 - Water Service Area
■ Section 3 - Existing Water Supply Facilities
■ Section 4 - Population and Demand Projections
■ Section 5 - Water Supply Facilities Work Plan

Section 2
Water Service Area
2.1 MDWASD Service Area
The MDWASD water service area contains interconnected systems and thus, for the
most part, functions as a single service area. However, for the convenience of
discussing existing facilities, the service area may be broken down into three subareas
by water treatment facilities: the Hialeah -Preston area serving the northern part of
Miami -Dade County, the Alexander Orr, Jr. area serving the central and portions of
the southern part of Miami -Dade County and the South Dade area (formerly known
as the Rex Utility District) serving the southern part of Miami -Dade County, shown
on Figure 2-1.
Within the MDWASD service area 16 wholesale customers. The City of North Miami
Beach will stop purchasing water from MDWASD in 2008. The City of North Miami
Beach will remain a wholesale customer until them. Table 2-1 identifies the 16
wholesale customers and the status of their large user contracts.
2.2 Hialeah -Preston Subarea
The Hialeah -Preston (H -P) subarea is comprised of dedicated low-pressure pipelines,
remote storage tanks, pumping facilities and high pressure systems. This system
delivers water to Hialeah, Miami Springs, the City of Miami and other portions of
northeastern Miami -Dade County, shown on Figure 2-2, generally north of Flagler
street.
2.3 Alexander Orr, Jr. Subarea
The Alexander Orr, Jr. (AO) subarea is comprised of a high pressure system
comprised of two major piping loops. This system delivers water to nearly all of
Miami -Dade County south of approximately Flagler Street and north of SW 248th
Street, including Virginia Key, Fisher Island, the Village of Key Biscayne and, upon
request, to the City of Homestead, and Florida City, shown on Figure 2-3.
2.4 South Dade Subarea
The South Dade subarea consists of small distribution systems and storage tanks that
evolved around each individual water treatment plant (WTP) within each WTP's
distinct service areas. These systems deliver water to nearly all of Miami -Dade
County south of S.W. 248th street and east of S.W. 197th avenue. Homestead and
Florida City are within this area, but provide water service only within their
incorporated boundaries. Figure 2-4 shows the South Dade subarea.
MDWASD has plans for the construction and operation of the South Miami Heights
(SMH) WTP in the South Dade subarea. Of the five existing plants in the South Dade
subarea, only Everglades and Newton WTPs will remain in service after the
SMHWTP begins operations. The existing distribution and storage systems will be
incorporated into the future plans. A general shift will occur in the northern boundary

of the South Dade subarea once the proposed South Miami Heights Water Treatment
Plant comes into service in 2012. The northern boundary will be shifted northward
such that portions of the population currently within the Alexander -Orr subarea will
be within the South Dade subarea. Figure 2-1 and 2-4 illustrate the boundary shift.
The boundary shift will cause a general redistribution of service between the
Alexander -Orr and South Miami -Dade areas, but will not have other effects on the
population expected to be served by MDWASD.
2.5 Other Water Suppliers (Non-MDWASD)
Miami -Dade County has facilities belonging to other water suppliers located within
its boundary. These facilities are located in the extreme northern and extreme
southern parts of the county.
The City of North Miami and the City of North Miami Beach provide service to parts
of northern Miami -Dade County within their municipal boundaries, as well as
outside of their municipal boundaries extending into the northeastern and
northwestern parts of the County.
The City of Homestead and Florida City have facilities and/or provide service to

Existing Water Supply Facilities
3.1 Water Supply Wellfields (Sources of Water)
The MDWASD water system is currently served by the previously mentioned three
large treatment plants and the smaller treatment plants in the southern portion of
Miami -Dade County. The existing water supplies serving these treatment plants
originate from two major aquifer systems in Miami -Dade County: the Surficial and
the Floridan Aquifer Systems. The Surficial Aquifer System, also known as the
Biscayne Aquifer, is the major source of drinking water and occurs at or near the land
surface in most of the County, and is the principal water -bearing unit of the Surficial
Aquifer System in the region (Causaras,1987). Groundwater from the Floridan
Aquifer is used for blending at the Alexander Orr, Jr. Water Treatment Plant (WTP).
MDWASD has been operating under the Miami -Dade Interim Consumptive Use
Authorization and Agreement dated May 10, 2006 between the SFWMD and Miami -
Dade County. This agreement allowed MDWASD to withdraw up to 349.76 MGD
with a maximum month of 11,140 million gallons until November 15, 2007, when the
20 -Year water use permit was approved by the SFWMD Governing Board
3.1.1 Wellfields and Capacities
The existing MDWASD water supply system is comprised of eight major Biscayne
Aquifer wellfields in the Hialeah -Preston and Alexander Orr, Jr. subareas, twelve
Biscayne Aquifer water supply wells located at five individual water systems
(formerly Rex Utility District water system) in South Dade County and the Floridan
Aquifer blending wells at the Alexander Orr, Jr. Subarea, as shown in Table 3-1 and
Figure 3-1. Each of the wellfield is described below.
3.1.2 Hialeah -Preston Subarea Wellfields
The Hialeah -Preston WTPs are supplied by four water supply wellfields, shown on
Figure 3-1. The total designed installed capacity from the four wellfields in the
Hialeah -Preston subarea is approximately 295 mgd. Appendix A provides detailed
information about well construction and capacities of the Hialeah -Preston area
wellfields.
In addition to these wellfileds, four abandoned wells at a medley wellfield have been
rehabilitated and would be available on a stand-by basis in the event of an
emergency.
3.1.2.1 Hialeah Wellfield
The three active wells located in the Hialeah Wellfield were constructed in 1936. Each
well is 14 inches in diameter, 115 feet deep and have casing depths of 80 feet. The total
wellfield capacity is 12.5 mgd or 8,700 gpm (2,900 gpm for each well).

The total wellfield capacity is 43.20 mgd or 30,000 gpm (7,500 gpm for each well).
3.1.3 Alexander Orr, Jr. Subarea Wellfields
The Alexander Orr, Jr. WTP is supplied by four water supply wellfields as shown on
Figure 3-1. The total designed installed capacity from the four wellfields in the
Alexander Orr, Jr. service area is approximately 308 mgd. There are Floridan aquifer
wells at two of the wellfields. Appendix A provides detailed information about well
construction and capacities, of the Alexander Orr, Jr. area wellfields.
3.1.3.1 Alexander Orr, Jr. Wellfield
The ten active wells located in the Alexander Orr, Jr. Wellfield were constructed
between 1949 and 1964. These wells are 16 inches and 42 inches in diameter, 100 feet
deep and have casing depths ranging from 40 to 50 feet. The capacity of the wellfield
is 74.4 mgd (ranging between 4,170 and 7,500 gpm for each well). Because this
wellfield is closest to saline water, there exist the potential for saltwater intrusion, as
has occurred in the past. Improvements to a control structure on the C-2 Canal has
assisted in reducing saltwater intrusion in recent years.
3.1.3.2 Snapper Creek Wellfield
The four active wells located in the Snapper Creek Wellfield were constructed in 1976.

limited to 5 mgd; Well No. 30 is limited to 10 mgd; and Well No. 31 is to be used as a
standby well only to be used with prior written approval from the SFWMD.
3.1.3.5 Floridan Aquifer Blending (and ASR)
Three Upper Floridan Aquifer wells are located in the West Wellfield and two are
located in the Southwest Wellfield. Currently, there are Upper Floridan Aquifer wells
in service and the blending of brackish and fresh water is occurring in the raw water
line feeding the Alexander Orr, Jr. WTP. These wells were constructed in 1996 and
1997 and are 30 inches in diameter. The total depth of these wells is between 1,200
feet and 1,300 feet with casing depths between 835 feet and 850 feet. The total
capacity of the West Wellfield wells is 15.12 mgd or 3,500 gpm per well. The total
capacity of the Southwest Wellfield wells is 10.08 mgd or 3,500 gpm per well.
MDWASD also anticipates using these wells for storage of fresh Biscayne Aquifer
water in the Floridan Aquifer occasionally during the wet season (when operating
water levels in canal permit) for extraction and use in the dry season. To do so,
MDWASD designed an ultra -violet (UV) light disinfection system for each ASR site to
treat the Biscayne aquifer water before injecting in the Floridan aquifer.
3.1.4 South Dade Subarea Wellfields
The five South Dade WTPs are supplied by five individual water supply wellfields as

Existing Water Supply Facilities
Preston subarea, generally, the service area that lies north of Flagler Street. The two
plants have similar treatment processes, which are described separately below.
3.2.1.1 Hialeah Water Treatment Plant (WTP)
The Hialeah WTP was originally designed in 1924 with a total capacity of 10 mgd. By
1935, the plant's capacity totaled 40 mgd. In 1946, capacity was increased to 60 mgd.
Air strippers with a capacity of 84 mgd were added to the treatment process in 1991 to
remove volatile organics from the finished water. A 3.2 MG storage reservoir for both
the Hialeah and John E. Preston WTPs was also added in 1991. There are plans to
rerate and upgrade the Hialeah WTP to a capacity of 70 mgd, if necessary.
The source water for Hialeah WTP is from the Hialeah -Miami Springs Wellfields,
supplemented by the Northwest Wellfield. The Hialeah WTP has a current rated
capacity of 60 mgd. The treatment process includes lime softening with sodium
silicate activated by chlorine, recarbonation, chlorination, ammoniation, fluoridation,
filtration, and air stripping. The plant site is relatively small, and is surrounded by
residential areas.
3.2.1.2 John E. Preston Water Treatment Plant
The John E. Preston WTP was originally designed as a 60 mgd plant in 1968 and
upgraded to 110 mgd in 1980. The plant was rerated to a total capacity of 130 mgd in
1984. The plant reached its present capacity of 165 mgd with another addition in
1988. In 1991, the plant was modified with an air stripping capacity of 185 mgd to
remove VOCs. In 2005, the plant process modifications to provide enhanced
softening for reduction of color and total organic carbon came on line.
The main source of water for the Preston WTP is from the Northwest Wellfield. The
current rated capacity is 165 mgd with a treatment process similar to that of the
Hialeah WTP. This includes lime softening with ferric and other coagulant and
chemicals added prior to lime for enhanced softening, recarbonation, chlorination,
ammoniation, fluoridation, filtration, and air stripping. The Preston plant is also sited
in a residential area of Hialeah.
3.2.2 Alexander Orr, Jr. Water Treatment Plant
The Alexander Orr, Jr. WTP is located at 6800 S.W. 87th Avenue in Miami. The original
design capacity was 40 mgd in 1954. This plant has undergone several expansions
during the past 50 years. The raw water pumping capacity was increased by 32 mgd
to 262 mgd in 1995 with an additional source from the West Wellfield. Additional
reservoir and high pressure service capacities were also added to bring the total plant
design capacity to 256 mgd. The plant rated capacity is 217.74 mgd.
The Alexander Orr, Jr. WTP receives its source water from the Alexander Orr, Jr.
Wellfield, Snapper Creek Wellfield, Southwest Wellfield, and the West Wellfield. The
Alexander Orr, Jr. WTP treatment process is similar to the other two major plants
utilizing lime softening with activated sodium silicate added prior to lime as a

coagulant aid, recarbonation, fluoridation, chlorination, ammoniation, and filtration.
Unlike the Hialeah and Preston WTPs, this plant does not utilize enhanced softening
or air stripping towers. Finished water is distributed to a service area generally
delineated as south of Flagler Street.
3.2.3 South Dade Water Treatment Plants
In 1985, MDWASD purchased an existing private utility known as the Rex Utility
District Water System. Today, this system is referred to as the South Dade Water
System. At the time of purchase, the system consisted of six plants and associated
wellfields. Since the time of purchase, the Redavo WTP has been taken out of service.
The South Dade Water System is currently made up of five small WTPs that draw
groundwater from the 12 wells located at the plant sites. The five small plants serving
the South Dade Service Area include Elevated Tank, Everglades Labor Camp, Leisure
City, Naranja, and Newton WTPs. These plants are located in the Southern portion of
the County as shown on Figure 3-2. The plants utilize in-line disinfection with free
chlorine and stabilization with the addition of polyphosphate. The two-year average
annual daily flow (ADF) for the plants ranges from approximately 0.2 mgd at Naranja
to over 3 mgd at Leisure City. This system serves a population of approximately
15,500 in the Leisure City, Everglades Labor Camp, and Naranja areas excluding the
cities of Homestead and Florida City, which provide their own water service. These
small treatment plant capacities are limited by the pumping capabilities at each plant.
It is anticipated that these treatment plants will be replaced by the proposed South
Miami Heights WTP by 2012.
MDWASD has plans for the construction and operation of the South Miami Heights
(SMH) WTP in the South Dade subarea. Of the five existing plants in the South Dade
subarea, only Everglades and Newton WTPs will remain in service when the SMH
WTP comes into service in 2012. The total annual average daily demand for the
future South Miami Heights WTP will be approximately 18 mgd.
3.2.4 Finished Water Storage
3.2.4.1 Hialeah Preston Subarea
The finished water storage facilities for the Hialeah -Preston subarea consist of both
"in -plant" and remote storage facilities. The storage facilities are summarized in
Table 3-2.

3.2.4.2 Alexander Orr, Jr. Subarea
The water storage facilities of the Alexander Orr, Jr. subarea consist of a 39 -MG
ground storage tank located at the WTP site and a 1.6 -MG plant clear well.
3.2.4.3 South Dade Subarea
The South Dade Subarea currently has no significant storage facilities. Therefore, the
system is very vulnerable to emergency situations.
MDWASD has plans for the construction and operation of the South Miami Heights
WTP in the South Dade subarea. Within those plans, a 5 MG reservoir is being
planned for on-site plant finished water storage.
3.3 Water Distribution Facilities
The MDWASD water distribution system is currently supplied by the three large
treatment plants and the smaller treatment plants in the southern portion of Miami -
Dade County. The distribution systems serving these treatment plants are comprised
of loops and are interconnected, as shown on Figure 3-2.
3.3.1 Hialeah -Preston Subarea
Finished water from the Hialeah and John E. Preston WTPs is pumped through a
system of dedicated low-pressure pipelines to remote storage tanks and pumping
facilities. This system provides water service to the southeastern part of the Hialeah -
Preston subarea. The low pressure system starts at the Hialeah WTP with a 42 -inch
diameter main heading due east along N.W. 62nd Street, and 36 -inch and 42 -inch

diameter mains running southeast along Okeechobee Road then parallel to the Miami
River. The main on N.W. 62.d Street connects to the N.W. 67th Street pumping station,
which pumps the water to the south through a 30 -inch diameter main running along
N.W. 10th Ave. The 30 -inch diameter main continues south and connects into the N.W.
36th Street pumping station. This main continues further south and connects into the
golf ground pump station.
The 36 -inch and 42 -inch diameter mains combine into a 54 -inch diameter main at
N.W. 42.d Avenue. They split again into a 36 -inch and a 42 -inch diameter main at
N.W. 32nd Avenue. These mains connect to the 30th Avenue pump station. The 30th
Avenue pump station feeds two 36 -inch diameter mains that connect to the 20th Street
pumping station to complete the loop. The pipe loop is made predominantly of
concrete and cast iron pipes that were installed in the early 1930s. Some segments of
this loop having been in service for more than 60 years. Replacement of these pipes
are scheduled in the Department maintenance program.
The remaining part of this subarea is served by a high pressure system. Water is
pumped into the system by five high service in -plant pumps with a total capacity of
34.1 mgd at 167 feet total dynamic head (TDH). The high pressure system delivers
water service to Hialeah, Miami Springs, and a high pressure main connected to the
City of Miami. The northern section of the subarea is supplied by one major piping
loop. The loop begins at the plant with a 60 -inch diameter main heading north along
West 4th Avenue (N.W. 57th Ave.) to N.W. 191St Street. At this location, it turns east
until it reaches N.E. 20th Avenue. It then turns south and connects into a 54 -inch
diameter main that connects to the N.W. 67th Street pumping station.
The southwestern portion of the subarea is supplied by a 36 -inch diameter main that
connects to the 60 -inch diameter main heading out of the John E. Preston WTP at
West 23,d Street. The main heads west on N.W. 74th Street then turns south on N.W.
107th Avenue. It eventually interconnects with the Alexander Orr, Jr. subarea piping
network on S.W. 8th Street around S.W. 11 Th Avenue.
3.3.2 Alexander Orr, Jr. Subarea
The distribution system of the Alexander Orr, Jr. subarea is comprised of two major
piping loops. The first major loop traverses the south and west portion of the subarea.
The loop starts at the WTP with a 60 -inch diameter main heading west on S.W. 64th
Street and a 48 -inch diameter main that runs south along S.W. 87th Avenue (Galloway
Road) until S.W. 216th Street. The 48 -inch diameter main then heads west along S.W.
216th Street to a tee connection at S.W. 127th Avenue. One branch of the tee runs north
on S.W. 127th Avenue to S.W. 184th Street and then turns west to 137th Avenue. The 48 -
inch diameter main travels north on 137th Avenue to S.W. 152nd Street, where it
connects into a 24 -inch diameter main running east -west on 152nd Street and a 36 -inch
diameter main that continues north on 137th Avenue to S.W. 120th Street. There, the 36 -
inch diameter main turns west, then runs north along Hammocks Boulevard to S.W.
88th Street where it reduces to a 24 -inch diameter main that runs north along S.W.

152nd Avenue to 72nd Street. The 24 -inch diameter main then runs east -west on S.W.
72nd Street. At S.W. 1471h Avenue, it connects with a 36 -inch diameter main that runs
north to S.W. 56th Street (Miller Road), where it connects with a 42 -inch diameter main
that runs east on Miller Road. This 42 -inch diameter main enlarges to a 48 -inch
diameter main that eventually connects to the 60 -inch diameter main at the
intersection of Miller Road and S.W. 117th Avenue to complete the loop. A 36 -inch
diameter main branches off of the 60 -inch diameter main at the intersection of Miller
Road and S.W. 117th Avenue. This 36 -inch diameter main heads north along S.W. 117th
Avenue and eventually interconnects the Alexander Orr, Jr. and the Hialeah -Preston
subareas.
The second loop starts at the WTP with two 48 -inch diameter mains. One main runs
north on S.W. 87th Avenue (Galloway Avenue) to S.W. 40th Street (Bird Road) and then
turns east. The main continues east along Bird Road, reduces to a 42 -inch diameter
main at N.W. 57th Avenue, then connects through a 30 -inch diameter pipe connection
with the second 48 -inch diameter main at Bird Road and S.W. 37th Avenue (Douglas
Road). The second 48 -inch diameter main travels along Highway 874 to S.W. 56th
Street, where it turns east then northeast between S.W. 67th Avenue and S.W. 62nd
Avenue to S.W. 48th Street. The main runs east on S.W. 48th Street then northeast
through several changes in direction, where it connects to the other 48 -inch diameter
main at Bird Road and S.W. 37th Avenue. The main then travels north along South
Dixie Highway and eventually interconnects with the Hialeah -Preston Service Area
piping network through a 36 -inch diameter pipe that runs along S.W. 2nd Avenue.
3.3.3 South Dade Subarea
The South Dade water distribution system consists of small water mains with
diameters ranging from 16 inches to 4 inches. The distribution system is centered
around each individual WTP. Each has its own sets of water main loops within the
distinct service areas. The Leisure City, Elevated Tank, and Naranja WTPs, however,
are so well interconnected that they can be generally considered as one distribution
area. More than 63 percent of the South Dade subarea is served by these three plants.
The distribution system of these three plants form one major loop that is bounded on
the north by S.W. 248th Street, on the south by S.W. 304th Street, on the east by S.W.
117th Avenue, and on the west by S.W. 172nd Avenue.
The Everglades Labor Camp WTP serves a small area that is bounded on the north by
S.W. 376th Street, on the south by S.W. 384th Street, on the east by S.W. 192nd Avenue,
and on the west by S.W. 194th Path. This distribution system consists of one 12 -inch -
diameter loop around the service area interconnected with several 8 -inch diameter
distribution mains. The Everglades Labor Camp and the Newton WTP distribution
system are interconnected via an 8 -inch diameter main that runs east along S.W. 376th
Street then heads north on S.W. 187th Avenue, where it connects with a 12 -inch
diameter main at S.W. 360th Street. The 8 -inch diameter main continues north on S.W.
187th Avenue until S.W. 352nd Street, where it connects into a small distribution loop
that terminates with a 16 -inch diameter stub -out.
3-12

Existing Water Supply Facilities
The Newton WTP distribution system consists of a single 12 -inch diameter water
main that runs east and west on S.W. 3361h Street. The eastbound main then branches
north and south along S.W. 152nd Avenue. The southbound branch then turns east on
S.W. 344th Street and ultimately connects to the FP&L Turkey Point generating plant.
The northbound branch continues along S.W. 152nd Avenue, where it connects to the
Leisure City WTP distribution system at S.W. 304th Street. A 6 -inch diameter main
running south from SW 288th Street on S.W. 137th Avenue then east on S.W. 328th
Street connects to an 8 -inch diameter main that runs south on 117th Street. This 8 -inch
diameter main connects to the 12 -inch diameter main to FP&L Turkey Point
generating plant. This main ultimately completes the interconnection of the Newton
WTP with the Leisure City, Elevated Tank, and Naranja WTPs' distribution areas.
The westbound branch of the 12 -inch diameter main turns south on S.W. 162nd
Avenue then heads south and west on Palm Drive. The main then continues south on
S.W. 167th Avenue then west on S.W. 36011, Street until it connects to the Everglades
Labor Camp WTP 8 -inch diameter main that runs north on SW 187th Avenue.
The South Dade distribution system is interconnected with the Alexander Orr
distribution system in the vicinity of SW 127th Avenue. MDWASD has plans for the
construction and operation of the South Miami Heights WTP and associated
wellfields in the South Dade Subarea. Of the five exsisting WTPs and wellfields in the
South Dade area, only Everglades and Newton WTPs and wellfields will remain in
service when the SMHWTP comes on line in 2012. MDWASD will be constructing a
water main to interconnect with the Everglades and Newton Systems to provide
water and meet additional future demands. The SMHWTP will connect to the existing
distribution systems of the South Dade Plants to be taken out of service in 2012, when
SMHWTP is online.
3.4 Summary
As shown within this section, the MDWASD water supply and treatment systems
have sufficient installed capacity to produce more potable water than is currently
required. Table 3-3 summarizes this information.

Section 4
Population and Water Demand Projections
This section presents historical and projected population projections from Year 2001
through Year 2030 for MDWASD's service area. Population data were obtained from
the Miami -Dade County Planning and Zoning (P&Z) Department and were derived
from Transportation Analysis Zone (TAZ). Further, the Consolidated Water Use
Permit Application (No. 040511-5) submitted to South Florida Water Management
District (SFWMD) in July 2005 indicates that the population data presented in this
section was accepted by SFWMD for its use in the Lower East Coast (LEC) Plan 2005-
2006 update. The Lower East Coast (LEC) Plan 2005-2006 update was approved on
February 15, 2007.
4.1 Historical Population
Historical populations served by the MDWASD system are shown in Table 4-1 in one
year increments from Year 2001 to Year 2006. The population in MDWASD's service
area grew approximately 7.3 % between Year 2001 and year 2006. Table 4-1 also
provides a summary of historical population within Miami -Dade County. The
MDWASD system served approximately 90% of the County total population in 2006.

4.2 Population Projections
Population projections for MDWASD's service area in five year increments from Year
2007 to 2027 and Year 2030 are shown in Table 4-2. Overall, the population served by
MDWASD is expected in increase approximately 26.2% from Year 2006 to Year 2030.
There are two important developments for the projected population distributions that
should be noted. The first development concerns the population of the City of North
Miami Beach currently served by MDWASD's water distribution system. The City of
North Miami Beach has filed for a water use permit and will be implementing an
alternative water use program that will allow the City to serve its entire population.
As a result, the City of North Miami Beach's population currently served by
MDWASD is expected to drop out by the end of 2007, resulting in a net negative
growth rate (-0.89%) in the population served by MDWASD between 2007 and 2008.
4-1
KM2740.Sec4.doc
11/26/2007
Water Facilities Master Plan
Population and Water Demand Projections
The second development (mentioned earlier) concerns a general shift in the northern
boundary of the South Dade area once the proposed South Miami Heights Water
Treatment Plant comes into service in 2012. The northern boundary will be shifted
northward such that portions of the population currently within the Alexander -Orr
subarea will be within the South Dade subarea. Figure 4-1 illustrates the boundary
shift. The boundary shift will cause a general redistribution of service between the
Alexander -Orr and South Dade areas, but will not have other effects on the
population expected to be served by MDWASD. In 2030, MDWASD will serve
potable water to approximately 87% of the total County population.

4.3 Historical Water Use
Historic water use figures were obtained from MDWASD and reflect water provided
by the Hialeah -Preston, Alexander -Orr, Everglades, Leisure City, Newton, Elevated
Tank, and Naranja WTPs and associated wellfields. These water use figures provide
the basis for forecasting future water demands for MDWASD's service area. Table 4-
3, referred to as Table F in previous submittals to MDWASD and the SFWMD,
provides the historical raw and finished water use by subarea for Year 2001 through
Year 2006. Information shown in Table 4-3 includes per capital annual average and
maximum month water use.
4.4 Water Demand Projections
The water demand projections presented herein are based on initial system -wide
finished water daily per capita use rate of 155 gallons per capita per day (gpcd). The
per capita use was determined by taking a 5 -year average from 2002 to 2006. The
initial per capita rate was adjusted to reflect reductions resulting from water
conservation and reuse irrigation water projects.
Table 4-4, referred to as Table G in previous submittals to the SFWMD, provides the
projected raw and finished water use for Year 2007 through Year 2030. Table 4-4 also
provides projected raw water pumpage from the Biscayne and Floridan Aquifers in

five-year increments to indicate how the sources of water will be used to meet future
demands.
4.5 Water Conservation and Reuse
The per capita usages contained in Table 44 are adjusted taking into consideration
MDWASD water conservation and reuse programs. WASD will be undertaking a 20 -
year water conservation plan and will evaluate ways for reducing non -revenue water.
Water Conservation projections were taken from the MDWASD 20 -year Water Use
Efficiency Goal Based Plan (Plan) approved by the SFWMD. Included in the Plan is
the Water Conservation Best Management Practices (BMP) Planning Spreadsheet
prepared by Malcolm Pirnie, Inc. in 2007. Values contained within Table 4-4 reflect
projections as of May 31, 2007. Water conservation projections do not reflect water
demand reductions presented by the "Unaccounted Water Loss Reduction Plan
(February 2007)" prepared by Malcolm Pirnie, Inc. and currently under review by
MDWASD. The potential additional reduction in water demands as a result of real
non -revenue water loss is estimated at 14.25 mgd over the next ten years.
Currently, MDWASD implements all BMPs included in the 20 -year plan in addition
to various irrigation, xeriscape and plumbing fixture efficiency ordinances and some
reuse within the three wastewater treatment plant sites or in their vicinities. A 7.0
mgd reuse irrigation project is anticipated at the North District Wastewater Treatment
Plant in 2012. A 1.0 mgd reuse irrigation project is anticipated at the Central District
Wastewater Treatment Plant in 2011. A portion of these projects will result in credits
against current or projected finished water demands as shown in Table 4-4.
4.6 Summary
In summary, the historically based projected water demands as adjusted for water
conservation and reuse are presented in Table 4-5 as "adjusted" finished water
demand and per capita water use. The resulting anticipated finished water demands
to 2030 in increments is as follows:

5.1 South Miami Heights Water Treatment Plant and
Wellfield
Start 2007
Finish 2012
Construction on the South Miami Heights Water Treatment Plant and Wellfield will
begin in 2007. This facility will use a parallel treatment train of ultra-low
pressure/ nanofiltration reverse osmosis and ultrafiltration membranes for treatment
of 20 mgd of Biscayne aquifer water from ten wells.
5.2 Alternative Water Supply Projects
The following proposed alternative water supply (AWS) projects are to meet
MDWASD's increased water demands through 2030, which encompasses the
proposed 20 -year Consumptive Use Permit period. AWS projects have been
identified to meet water demands in the MDWASD service area and are presented in
Table 5-1, Table 5-2 and Figure 5-1. These projects are to be completed in increments
commensurate with the projected growth, as presented in Figure 5-2 and Figure 5-3.
All costs are in terms of December, 2006 (ENR CCI=7888) dollars.
The plan described herein demonstrates that the proposed projects, by their location,
volume of water produced, and timing of implementation, will be sufficient to offset
the corresponding raw water demand increases. These projects will undergo further
refinement and development over the next few months. The flow (Q MGD) shown in
parentheses below represents the corresponding amount of finished water annual
average daily demand (AADD) provided by the projects in terms of million gallons
per day (MGD). These AWS projects and AADD assume that all current wholesalers
will remain on the MDWASD system through 2030, except the City of North Miami
Beach which drops out after 2007.

5.2.1 New Upper Floridan Aquifer Reverse Osmosis (RO) WTP
Start 2007
Finish 2028
A new upper Floridan aquifer reverse osmosis water treatment plant is to be
constructed. The exact location of this plant has not yet been determined, but is
expected to be in the northern part of the County (i.e., Hialeah). Ownership,
financing, and operational issues associated with the RO WTP is the subject of a Joint
Participation Agreement (JPA) between the County and the City of Hialeah, which
was approved by the Miami -Dade County Board of County Commissioners on July
26, 2007. Regardless of the outcome, the WTP will directly utilize the Floridan
Aquifer as the alternative water supply using the RO treatment to remove salt. The
County is currently preparing a Notice to Professional Consultants (NTPC) to select
the design professional for the project. It is anticipated that this plant will be
constructed to an initial capacity and its capacity expanded, as required, in three
phases, as described below.
5.2.1.1 Phase 1 (10 MGD)
Start 2007
Finish 2012
Phase 1 planning and design of this WTP will begin in the middle of 2007, with
construction and start-up extending to 2012. The Phase 1 production for this plant
will be 10 mgd. The Phase 1 cost is estimated at $93 million.
5.2.1.2 Phase 2 (5 MGD)
Start 2015
Finish 2018
Phase 2 planning and design of this WTP will begin in the middle of 2015, with
construction and start-up extending to 2018. The Phase 2 production for this plant
will be 5 mgd. The Phase 2 cost is estimated at $25 million.
5.2.1.3 Phase 3 (2.5 MGD)
Start 2025
Finish 2028
Phase 3 planning and design of this WTP will begin in the middle of 2025, with
construction and start-up extending to 2028. The Phase 3 production for this plant

blending AADD capacity to the County's water supply. This project uses the brackish
Floridan Aquifer water to blend with the fresh Biscayne Aquifer raw water.
MDWASD also anticipates using these wells for occasional storage of fresh Biscayne
Aquifer water in the Floridan Aquifer during the wet season for extraction and use in
the dry season. To do so, MDWASD designed a ultra -violet (UV) light disinfection
system for each ASR site. Project construction costs totaled $6.4 million (for the UV
system).
5.2.3 Floridan Aquifer Blending Wellfield at Hialeah -Preston
Water Treatment Plants (4.7 MGD)
Start 2006
Finish 2010
MDWASD is planning on constructing two Floridan Aquifer blending wells to supply
raw water to the Hialeah -Preston WTP complex. This project will further increase
AADD capacity by 4.7 MGD by blending the Floridan Aquifer water with the raw
water supply at an estimated cost of $10.3 million by 2010. This project is currently
under design by MDWASD.
5.2.4 North District Wastewater Treatment Plant (NDWWTP)
(7.0 MGD)
Start 2007
Finish 2011
This project is a 7 MGD reclaimed water (e.g. purple pipe) irrigation project at the
NDWWTP with an estimated cost of $26.8 million and its completion is scheduled for
2011. Part of the reclaimed water will be pumped to the City of North Miami Beach.
Approximately 2 MGD will be used to replace a current potable water irrigation in the
MDWASD service area as a potable water credit. MDWASD has prepared a NTPC
for selecting a Consultant to design the project, and will take the requests to advertise
to the December 2007 Board of County Commissioners.
5.2.5 Central District Wastewater Treatment Plant (CDWWTP)
(1.0 MGD)
Start 2007
Finish 2011
This project is a 1 MGD reclaimed water (e.g. purple pipe) irrigation project at the
CDWWTP with an estimated cost of $15.3 million and its completion is scheduled for
2011. The project will replace potable water irrigation at Crandon Park and certain
areas of Key Biscayne as a potable water credit. MDWASD has prepared a NTPC for
selecting a Consultant to design the project, and will take the requests to advertise to
the December 2007 Board of County Commissioners.

5.2.6 South District Wastewater Treatment Plant (SDWWTP)
5.2.6.1 Phase 1 (18 MGD)
Start 2007
Finish 2014
Phase 1 of the Groundwater Replenishment (GWR) project at the South Miami
Heights WTP is scheduled to be ready for implementation by 2014 expanding the
finished water AADD by 18 MGD at a cost of $357.5 million. MDWASD has prepared
a NTPC for selecting a Consultant to design the project, and will take the requests to
advertise to the December 2007 Government Operations and Environment Committee
Meeting. Design could be completed by mid -2009. This potential certified project
will provide advanced treatment of 30 MGD of secondary effluent to produce
approximately 23 MGD of highly treated reclaimed water that will be piped to
replenish ground water for water supply purposes. The technologies to be used
include micro -filtration and reverse osmosis which filters out small particles and uses
ultraviolet light for disinfection. High quality water would be piped to areas
upgradient of the proposed South Miami Heights wellfield and discharged into the
groundwater through underground trenches. Based upon this replenishment of
water, more water can be withdrawn and treated for drinking water purposes at this
treatment plant. This approach will enable the continuous use of the South Miami
Heights WTP, which will be constructed over the next four to five years.
5.2.6.2 Phase 2 (20 MGD)
Start 2015
Finish 2021
Phase 2 of the GWR for the Alexander -Orr WTP will add 20 MGD to the water supply
with total costs estimated at $482 million. The methodology used at the South Miami
Heights WTP will also be used for the Alexander -Orr WTP to replenish groundwater.
The GWR at Alexander -Orr, potential certified projects, will be available to initialize
operations in 2021. Alternately, MDWASD is looking at the option of constructing a
new West District Water Reclamation Plant (WDWRP) to produce high quality
recharge water to offset groundwater withdrawals in the Alexander Orr subarea
wellfields namely, increased withdrawal at the Southwest Wellfield. This plant is
scheduled to come on line in 2020.
Alternatively, MDWASD recently completed the Interim Wastewater Facilities Master
Plan, which recommends the establishment of the West District Water Reclamation
Plant (WDWRP), combined with wastewater storage facilities for peak wet weather
conditions in the Central West area of the County.

Phase 3 of the GWR at Alexander -Orr will add 15 MGD to the water supply and is
scheduled to be in operation in 2026 at a cost of $317 million. Originally, the Phase 3
GWR would be supplied by the SDWWTP. This plan was modified by the recently
completed MDWASD Interim Wastewater Facilities Master Plan, which recommends
the establishment of the West District Water Reclamation Plant (WDWRP), combined
with wastewater storage facilities for peak wet weather conditions in the Central West
area of the County. The WDWRP will produce high quality recharge water to offset
groundwater withdrawals in the Alexander Orr subarea wellfields namely, increased
withdrawal at the Southwest Wellfield. This plant is scheduled to come on line in
2020.
5.2.7 Miscellaneous Projects (19.62 MGD)
5.2.7.1 Water Conservation/Non-Revenue Potential Water Loss Reduction
Program
Start 2006
Finish 2026
These projects serve to reduce the demand for water through demand management.
They include, but are not limited to, various water conservation projects currently
being implemented by MDWASD. The County's Water Use Efficiency Five -Year Plan
was approved by the Board for the next five years and has been expanded to cover
the next 20 years with a projected reduction in demand of 19.62 MGD over that time
period. That represents more than 10% of the additional supply required to meet
future demands. Examples of ongoing conservation projects include the bathroom
and kitchen retrofits program, Miami -Dade green lodging and restaurant program,
low income seniors full retrofit program, rebates for high efficiency toilets and
washers, and landscaping irrigation evaluations. Similarly, the Non -Revenue Real
Water Loss Program identified potential reductions in water demand of as much as
14.25 MGD by 2030 through demand management activities.
5.2.7.2 Coastal Wetlands Rehydration Demonstration Project (0.25 mgd)
Start 2006
Finish 2014
The Coastal Wetland Rehydration (CWR) program is an example of a project that will
serve to reach effluent reuse goals of Miami -Dade County. The 0.25 MGD CWR
demonstration project is estimated to cost $19.2 million with a project end date in
2009, whereas costs for the full scale 78 MGD plant are estimated at $621 million with
a project completion date in 2014. The wetland rehydration process requires
thorough removal of nutrients from the reuse water and is consistent with the
Comprehensive Everglades Restoration Program (CERP), which envisions reused
wastewater as a practical water supply source for this purpose. A pilot project to test

Water Facilities Master Plan
Water Supply Facilities Work Plan
different treatment technologies and to gain insights into the biological and ecological
response of typical wetlands to highly treated effluent has been contemplated in the
CERP and is a current requirement in the Agreement with the SFWMD. The results of
the demonstration project will help to optimize the treatment system and the
preferred areas for rehydration to maximize the benefits to the wetlands and to the
Bay. The demonstration project advances the current CERP schedule by several years
and provides a unique opportunity to accelerate this aspect of the Everglades'
restoration. Currently, the Department and the SFWMD are reevaluating this
project's scope and size. The Agreement with the SFWMD will be modified when the
project's scope is agreed upon.
5.2.7.3 Aquifer Recharge Pilot Study (20,000 gpd)
Start 2006
Finish 2009
The aquifer recharge pilot study is an example of a project that will serve to reach
effluent reuse goals of Miami -Dade County. Costs for the aquifer recharge pilot study
are estimated at $1.5 Million with a completion date of 2009. The purpose of this
project is to demonstrate the ability of the reuse treatment pilot plant, and the
treatment processes, to produce a high quality reclaimed water for recharging the
Biscayne aquifer.
5.3 20 -Year Work Plan and Capital Improvement Plan
As demonstrated in the previous sections, the Alternative Water Supply Plan being
proposed by the County should meet the increased water demands through 2030. As
a confirmation that the County is committed to fund these projects, the projects for the
20 -Year Work Plan have been included in the County's Capital Improvement
Element. A copy of Tables 8 and 12 from the County's Capital Improvement Element
is contained within Appendix D and summarized in Table 5-3 for the next 5 years
(2008 - 2012).
5.4 Conclusion
In conclusion, and as Table 54 shows, MDWASD has prepared a work plan which
demonstrates that Department (e.g. public) facilities are available to meet the
projected growth demands (which reflect credits for conservation and for
reuse/reclaimed water). As noted on the table, regarding Permitted Amounts, these
amounts are pending the issuance of the 20 -year Consumptive Use Permit (CUP) by
SFWMD, and in turn the CUP is pending MDWASD's completion of the analyses
required under the SFWMD/Miami-Dade County Interim Agreement, which expires
in November 2007. So far, MDWASD has met all the deadlines for deliverables under
the Interim Agreement. The amounts raw water allocation in the anticipated in the
CUP will equal the projected demands.

Notes:
1. gpm = gallons per minute; MGD = million gallons per day; C = Centrifugal; T = Turbine; N/A = Not Available
2. Initial source for capacity information was extracted from the 2002 Water Facilities Master Plan. After site visits from MSA and documents provided by
MDWASD well operator, conflicting information was provided to senior MDWASD staff for verification. When required, changes were made accordingly.
3. Information other than capacity information is based on data included in the South Dade Water Use Permit provided by MDWASD staff.
4. Well number in parenthesis represent the number of the wells as previously provided to the SFWMD in Item II -2A, Table A - Well Description Tables.
5. Capacity of Northwest Wellfield assumes that only the low speed flow rate of 10 MGD can be achieved from each well with all wells pumping (except for 9.35 for
well #10.) If all pumps were to be run at high speed, the capacity of the wellfield would increase by an additional 71.59 MGD for a total of 220.94 MGD.
6. Wells in this wellfield had been abandoned. They were recently restored with the purpose of using them only for emergency purposes.

APPENDIX C
Water Supply for Municipalities
Appendix C
Water Supply for Municipalities
Miami -Dade Water and Sewer Department's (MDWASD) 20 -year Water Supply Facilities
Work Plan (WSFWP) identifies alternative water supply projects, conservation and reuse
programs, and capital improvement projects necessary to meet the projected water demands
within the Department's service area. The MDWASD's service area covers the entire
Miami -Dade County within the Urban Development Boundary (UDB), excluding portions of
North Miami and North Miami Beach, Homestead and Florida City. In 2008, North Miami
Beach will no longer be supplied by MDWASD. The areas within the Urban Expansion are
included in the planning horizon after 2015. Future water supplies for municipalities within
the MDWASD's service area are included in the 20 -year WSFWP. A list of all
municipalities including municipal and service area population, and water demands as
incorporated in MDWASD's projections is shown in Exhibits 3-1 through 3-3.
Currently, MDWASD is implementing all Best Management Practices (BMPs) included in
the 20 -year Water Use Efficiency Plan, which was approved by the South Florida Water
Management District in May 2007. The Plan identifies a total of approximately 20 mgd of
water saved through the year 2030. In addition, all of MDWASD's wholesale customers are
required to submit a Water Conservation Plan to the Department's Water Use Efficiency
Section as mandated by County Ordinance 06-177, Section 32-83.1 of the Miami -Dade
County Code. The Plan will identify BMPs based on population characteristics and type of
service for each municipal service area. The implementation of all BMPs in MDWASD's
service area will result in a reduction in per capita usage as identified in Section 4, Table 4-4
of the WSFWP. In addition, Miami -Dade County has developed recommendations for new
development that would achieve higher water use savings than currently required by code.
The recommendations were developed by an Advisory Committee and were presented to the
Board of County Commissioners (BCC) on June 5, 2007. These Water efficiency
recommendations are anticipated to be adopted by Ordinance by the end of 2007, and
represent an additional 30% to the water savings identified in the 20 -year Water Use
Efficiency Plan. All applicants will be required to comply with these future code
requirements. The list of recommendations submitted to the BCC is presented in Appendix
D and is also posted in the Miami -Dade Water Conservation Portal.
Exhibits 3-1 through 3-3 present all the municipalities within Miami -Dade County, as well as
their municipal population and service area population. Also included are the water demand
projections using a system wide per capita of 155 as included in the Department's Alternative
Water Supply Plan. Population data was obtained from the Miami -Dade County Department
of Planning and Zoning (P&Z) and was derived from Transportation Analysis Zone (TAZ).
The implementation of all BMPs identified in the 20 -year Water Use Efficiency Plan and in
the reuse programs included in the MDWASD's Alternative Water Supply Plan will result in
an adjusted system wide per capita by year 2027 of 146.72.

Water Use Efficiency
Recommendation
MIAM
,.,
Memo rant-hun COUNTY
Date: June 5, 2007
To: Honorable Chairman Bruno A. Barreiro and Agenda Item No. 12 (B) 3
Members,Bo rd of County Commissioners
From: George M.
County
Subject: Set of standards and directions for the development community that addresses
water conservation issues and alternative water supplies
At the request of the Government Operations and Environment Committee Chair, an Advisory
Committee was established with the goal of developing countywide guidelines that address
water conservation issues and alternative water supplies for the development community,
specifically, for new development. The Advisory Committee is comprised of several
departments including the Department of Environmental Resources Management, the General
Services Administration, the Building Department, Park and Recreation, Planning and Zoning,
the Building Code Compliance Office, the Fire Department, the Public Works Department and
the Water and Sewer Department. In addition to County staff, the Advisory Committee
includes representation from stakeholder groups such as the American Society of Landscape
Architects, the South Florida Builders Association, the Sierra Club, the Latin Builders
Association, the Tropical Audubon, the Association of Cuban American Engineers, the Florida
Regional Planning Council, the Farm Bureau, the South Florida Water Management District,
the Audubon Society and the Greater Miami Chamber of Commerce.
The Advisory Committee held five meetings between January 26, 2007 and April 20, 2007.
These meetings were advertised in the County's meeting calendar and were open to public
comment. The Advisory Committee, as part of its review process, evaluated the documents
including "Green Building" practices, the Florida Friendly Landscape Guidelines and the
Florida Yards and Neighborhoods criteria.
The Advisory Committee has summarized its findings as shown on Attachment A which
consists of recommendations for 1) Residential New Construction, 2) Commercial
Development, 3) Alternative Water Supplies, and 4) Public Information/Education/Legislation
recommendations. In the first category, Residential New Construction, the recommendations
are divided into two parts, indoor water use specifications such as high efficiency toilets,
faucets, clothes washers, and outdoor water use specifications which include the
implementation of the Florida Friendly Landscape Guidelines, gutter downspouts, roof runoffs
and rain harvesting for recharge purposes as well as drip irrigation or micro -sprinklers.
Examples of recommendations made in the second category, Commercial Development, take
into account the use of automatic shut -offs, solenoids, controllers, flow restrictors, plumbing
fixtures for toilets and faucets, designs for toilet and fixtures that reduce the volume of water
wasted and the installation of overflow sensors on equipment cooling towers. The third
category, Alternative Water Supplies, bases its recommendations on the eventuality that water
service is not available in a particular area, as such the construction of a 1 million gallons per
Honorable Chairman Bruno A. Barreiro and Members,
Board of County Commissioners
Page 2
day reverse osmosis plant is proposed as an option or the construction of an alternative water
supply water treatment plant and distribution system. If water service is available and the area
is considered to be within a reuse zone, developers should consider installing "purple pipes".
The fourth category, Public Information/Education/Legislation provides recommendations on
the dissemination of public information and education and legislation regarding water
conservation.

b. Pre -rinse spray valves that use 1.6 gallons per minute and have a shot off valve.
Food Preparation
a. Use connectionless steamers. They do not need either a water supply or a wastewater drain.
b. Select ice machines that use no more than 20 gallons per hundred pounds of ice made.
Irrigation controllers
a. Soil moisture sensors or other water saving technologies shall be installed. Devices shall be installed and
function according to manufacturers' recommendations.
Irrigation equipment and design
a. Use drip irrigation or microsprinklers for planning beds (once plants are established, irrigation is not usually
needed).
b. Create hydrozoned areas, with beds and turf watered separately.
c. Design systems to maintain manufacturer -recommended pressure to prevent misting and unnecessary pipe
wear.
Soil
a. Do not add soil on top of tree roots.
Mulch
a. Use organic, preferably locally derived mulch, such as pine bark, dyed landscape mulch, or enviromulch.
Avoid cypress mulch which encourages deforestation of natural areas.
b. Limit use of rock mulch due to increased heat and reflection.
c. Mulch should be 3-4 inches deep over the root zone and several inches away from the base of plants.
Plant Selection
a. Use low -maintenance (drought tolerant) species. The Florida Extension Service's Florida Yards and
Neighborhoods Program list these species in a publication for South Florida. http://miami-
dade.ifas.ufl.edu/programs/fyn/publications/dtpl.htm.
b. Plant selection should be based on the plant's adaptability to the existing conditions present at the
landscaped area and native plant communities. Select plants that are drought and freeze tolerant.
c. For areas with limited soil space such as parking lots, use naturally small stature trees or use palms.
Information for small stature trees for restricted spaces, such as narrow swales and limited space residential
lots where canopy and roots can become problem can be found at http://miami-
dade.ufledu/programs/urbanhort/publications/PDF/Samll%20Trees%20for%20Miam i -Dade. pdf.
d. Florida -friendly landscape principles should be applied. These principles conserve water and protect the
environment and include efficient irrigation, practical use of turf, appropriate use of mulches, and proper
maintenance. (Ref. 373.185 F.S.).
Infrastructure Requirements
1. In the event that the MDWASD cannot provide services, the construction of Reverse Osmosis (RO) plants for
�» 3
S
developments equal or larger than 1 MGD water allocation.
a. Requirement of installation of a potable water treatment plant and distribution system. This requirement
should exempt the developer from water connection charges.
b. RO plants should be owned and operated by MDWASD — Chapter 24 language needs to be amended.
2. In the event that the MDWASD cannot provide services, the construction of satellite wastewater reclamation
facilities producing irrigation quality reclaimed water (62-610, Part III), larger than 100,000 gallons per day.
a. Modify language in Chapter 24 to allow for the construction of wastewater reclamation facilities plants
even if the project is within feasible distance of, or actually connected to sanitary sewers. The quality of
the treated effluent should be reviewed to possibly allow for a lower level of treatment for irrigation and
other uses.
b. Wastewater reclamation facilities should be owned and operated by MDWASD — Chapter 24 language
needs to be amended.
3. For developments where water supply is available, all developers should consider the installation of "purple
pipes" if the development is within a reuse zone and feasible distance from the "Mandatory Reuse Area" (MRA).
1. Expand "Factual Data" concept to encourage water conservation.
Revise Section 24-43.1(5) includes provisions for use of factual data in lieu of tabulated rates. Section can be
expanded to provide credits for the use of water saving strategies (e.g., reuse of gray water for toilet flushing, dual -
flush toilets, etc.).
NOTE: This will require similar adoption in MDWASD rules.
2. Add "Non -Revenue Water" ordinance to Chapter 24, Miami -Dade County Environmental Protection Ordinance.
Implement an Ordinance for "unaccounted-for" water (a.k.a. "non -revenue" water) that requires compliance with an
established standard. The ordinance shall be structured to address "real" and "apparent" water losses in accordance
with the principles established by the International Water Association (IWA) and IWA book 'Losses in Water
Distribution Networks - A Practitioner's Guide to Assessment, Monitoring and Control.' The ordinance can be
incorporated into Chapter 24, Miami -Dade County Environmental Protection Code and managed by the Department
of Environmental Resources Management (DERM) similar to the Volume Sewer Customer Ordinance.
3. Encourage the review and adoption of County ordinances for both:
• landscape protection, preservation and management, and for
• water conservation by the County and its municipalities
4. A Hot Water Recirculation System or Point -of -Use Hot Water heater shall supply water to hot water fixtures
further than ten linear feet of pipe away from the hot water heater. All hot water pipes shall be insulated.
5. Promote use of grey water for toilets and other uses discharging to public sanitary sewers.
6. All withdrawal from the aquifer should be metered including residential irrigation wells.
7. Landscape irrigation controller, soil moisture sensor, and irrigation system run time information. This sleeve
shall be connected to the irrigation controller for use by the homeowner.
