RESOLUTION NO. 57-21, A RESOLUTION OF THE VILLAGE COUNCIL OF THE VILLAGE OF
TEQUESTA, FLORIDA, RELATING TO THE FLORIDA DEPARTMENT OF ENVIRONMENTAL
PROTECTION (FDEP) STATE REVOLVING FUND (SRF) AND FORMAL ADOPTION OF THE
VILLAGE WATER FACILITY PLAN FOR THE IMPLEMENTATION OF WATER SYSTEM
IMPROVEMENTS; DESIGNATING THE VILLAGE MANAGER AS THE AUTHORIZED
REPRESENTATIVE TO PROVIDE ASSURANCES AND COMMITMENTS AS REQUIRED BY THE
FACILITY PLAN AND AUTHORIZING THE VILLAGE MANAGER TO REPRESENT THE VILLAGE IN
CARRYING OUT THE VILLAGE'S RESPONSIBILITIES UNDER THE FACILITY PLAN AND TO
DELEGATE RESPONSIBILITY TO APPROPRIATE VILLAGE STAFF TO CARRY OUT ACTIVITIES
ASSOCIATED WITH THE FACILITY PLAN; AND AUTHORIZING THE MAYOR TO EXECUTE THE
FACILITY PLAN; PROVIDING LEGAL AUTHORITY TO ADOPT, A CONFLICTS CLAUSE AND
SEVERABILITY CLAUSE; PROVIDING AN EFFECTIVE DATE; AND FOR OTHER PURPOSES.
In April 2021 the Village Council approved Resolution No. 19-21 implementing a 5-year rate schedule
for potable water services. This rate schedule was based on a Revenue Sufficiency &Rate Analysis
Study (Rate Study) performed by Raftelis Financial Consultants. One of the major goals of the study
was to fully fund the large capital needs within the system outlined in the long-term capital
improvements (CIP) program, particularly the water main replacement program. This important goal is
accomplished through a combination of operating revenues (pay -go funding) and State Revolving Fund
(SRF) loans.
Florida's SRF is made up of three programs - Clean Water State Revolving Fund (wastewater &
stormwater projects), Drinking Water State Revolving Fund (DWSRF) and State Revolving Fund
Management. Both the Clean Water and the Drinking Water SRF Programs are funded through money
received from federal grants as well as state contributions. These funds then "revolve" through the
repayment of previous loans and interest earned. The DWSRF Program provides low -interest loans to
local governments and private utilities to plan, design, and build or upgrade drinking water systems.
Interest rates on loans through the DWSRF are below market rates (discounted). The DWSRF financing
rate is determined using the Bond Buyer 20-Bond GO Index average market rate for the full weeks
occurring during the three months in the preceding fiscal quarter and applying that average rate to a
formula from the rule. There are up to 1.3 percent in additional rate reductions that may be assessed
based on Davis Bacon requirements, American Iron and Steel requirements, implement of an asset
management plan, and constructing a water conservation project.
To qualify for the DWSRF Program, entities must submit a Request for Inclusion (RFI) to be considered
at one of the quarterly Priority List Public Meetings. One of requirements to qualify for the discounted
loan program is the preparation and adoption of a Facility Plan (Planning Document). The planning
Page 182 of 222

document for first phase of projects (Water Main Replacement Projects 1 & 4) has been prepared by
Holtz Consulting in accordance with the DWSRF Program planning requirements.
If approved, the Request for Inclusion Form, Planning Document, design plans & specifications and
other documents will be submitted to the Florida Department of Environmental Protection for
consideration at the February 2022 Priority List Public Meeting.
NOTE: Due to document size, the complete Facility Plan and supporting attachments can be
obtained from the Utilities Department upon request.

risk category that applies. Flooded wells and wells under the direct influence of surface water are considered an unregulated
microbiological potential acute public health risk and require substantiated documentation of occurrence in lieu of sampling data.
7. Affordability Score. The extent of affordability existing in a small community to be served by the project shall be reflected in the
priority score. Points shall be awarded based upon two affordability criteria: namely, median household income (MHI) and service
area population (P). These points are to be added to the base priority score. Calculate the affordability score using the following
formula:
Affordability Score = (MHI Score + Population Score)
MHI Score = 100 x (1.00 — MHI/SHHI)
Zero < MHI score < 75, rounded to nearest whole number
Population Score = 50.0 - (P/200)
Population score > zero, rounded to nearest whole number
8. Water Conservation Score. A project sponsor with a qualifying water conservation project is eligible to receive an additional 100
points added to their priority score if the sponsor provides a water conservation plan in accordance with EPA's Water Conservation
Plan Guidelines web site liTtps:: w v�v3.epa.gov/�vaterseiiselpubsr rtilde.htm], document number EPA-832-D-98-001. The sponsor

Chapter 1.0 -Summary of Findings and Recommendations
This Water Facilities Plan was prepared for the Village of Tequesta to meet the requirements of the Florida
Department of Environmental Protection (FDEP) State Revolving Fund (SRF) loan funding of drinking water
systems. The Village of Tequesta (Village) is located in Palm Beach County and provides water service to the
Village's service area. Additionally, the Village has a service agreement with the Town of Jupiter Inlet Colony
as well an agreement for bulk water sale with South Martin Regional Utility via the Town of Jupiter Island.
The Village of Tequesta serves an estimated 13,240 resident population within its service area. Treated
water is distributed to approximately 5,044 accounts through approximately 72 miles of water mains. The
Village of Tequesta's average daily water demand is projected to be 3.47 million gallons per day (MGD) in
the year 2030 which is below the current permitted capacity of 6.3 MGD. The recommendations resulting
from this study are consistent with the Village's Comprehensive Plan.
The Village's water treatment plant generally consists of a 2.7 MGD maximum -day permitted sand filter
treatment process and a 3.6 MGD maximum -day permitted reverse osmosis (RO) treatment process. In
2000, the Village constructed the first phase of the RO treatment system to treat brackish water from the
upper Floridan aquifer (UFA), producing 1.2 MGD of finished water. The RO treatment system was expanded
in 2007 to produce 2.4 MGD and expanded again in 2011 to produce 3.6 MGD of finished water. The various
WTP expansions have resulted in treatment components and communications systems that are currently
not working at their optimum efficiency. The control systems hardware has been modified and compounded
as each upgrade or expansion has occurred and do not necessarily mesh well together. Additionally, there
are process control systems that can be upgraded, providing an increase in automation and allow more
control over the treatment processes. The proposed water treatment plant upgrades include process
efficiency and process automation upgrades in order to provide reliable drinking water to the Village
customers.
The Village's distribution system consists of approximately 380,000 LF of pipe sized from 4 to 16 inches. The
system is comprised of asbestos cement (AC), ductile iron, PVC and HPDE pipe. The oldest sections of the
distribution system are primarily comprised of AC water mains and were installed in the 1950s. Over the
past several years, there have been a number of AC water main breaks within the service area. As the pipe
in this area are between the ages of 40 to 60 years and have exceeded their anticipated service life
expectancy the Village is taking proactive measures and implementing asbestos cement water main
replacement projects to ensure the safe and reliable means of providing potable water to their customers.
The first project they will be seeking for is for the replacement of approximately 11,200 linear feet of 4-inch
through 10-inch water mains.
The project cost for the proposed water treatment plant upgrades is estimated at $2,932,000 and the AC
water main replacement is estimated at $2,320,488 for a total of $5,252,488.
The details of the capital costs are shown in Appendix A.
The pledged revenue for debt payments are the water charges by the Village of Tequesta. The SRF loan
will be repaid in 40 semi-annual installments.

Chapter 2.0 —Introduction
2.1 Background
The Village of Tequesta is located in northern Palm Beach County County, Florida along
Florida's East coast and is 18 miles north of West Palm Beach, Florida and 82 miles north of
Miami, Florida. Tequesta was founded in the 1950s as a planned community centered on
the Tequesta Country Club. The Village was incorporated in 1957. In 1955, author Charles
Martyn asked a local bridge keeper to describe the area that is now the Village of Tequesta.
The keeper described it as "a jungle." This intrigued Martyn who then decided to take the
bridge keeper on his boat and have him show him the interesting area. After traveling along
the Intracoastal, Martyn fell in love with the beauty of the area and its potential. He
purchased 86 acres on Jupiter Island and developed upon it the Jupiter Inlet Colony. While
excavating, Martyn's workers dug up a Native American mound full of artifacts. Martyn had
the contents researched and it was discovered the mound belonged to an encampment of
Tequesta Indians. The Tequesta Tribe lived in present-day Miami -Dade, Broward, and Palm
Beach counties and was second in power among tribes in Southeast Florida. Martyn named
the area he was developing west of the Intracoastal "Tequesta" in honor of the tribe. That
area, now called "The Tequesta Country Club," was later incorporated as part of the Village
of Tequesta. The Village of Tequesta is now miles of waterfront properties with beautiful
homes in quiet neighborhoods. It has a rich culture with many recreational activities like
shopping, dining, snorkeling, paddle boarding, and biking. Although the residential
population fluctuates with an increase in visitors during the winter months, the Village's
service area population was estimated to be approximately 13,240 based on the Village's
comprehensive plan.
The Water Utilities Department is responsible for the overall operation of the Village's
water system including the treatment and distribution of water to its service area
customers. The planning area, Figure 2-1, includes the entire service area.
2.2 Need
The project location map is presented in Figure 2-2. The Village's water treatment plant
generally consists of a 2.7 MGD maximum -day permitted sand filter treatment process and
a 3.6 MGD maximum -day permitted reverse osmosis (RO) treatment process. In 2000, the
Village constructed the first phase of the RO treatment system to treat brackish water from
the upper Floridan aquifer (UFA), producing 1.2 MGD of finished water. The RO treatment
system was expanded in 2007 to produce 2.4 MGD and expanded again in 2011 to produce
3.6 MGD of finished water. The various WTP expansions have resulted in treatment
components and communications systems that are currently not working at their optimum
efficiency. The control systems hardware has been modified and compounded as each
upgrade or expansion has occurred and do not necessarily mesh well together. Additionally,
there are process control systems that can be upgraded, providing an increase in

Chapter 3.0 -Environmental Impacts
3.1 Description of Planning Area
3.1.1 Planning/Water Service Area
The Tequesta water system service area extends beyond the Village corporate boundaries.
The present service area encompasses 14,338 acres. The current Village water system
serves portions of unincorporated Palm Beach County north of the Loxahatchee River and
south of the Martin County line; a portion of Southern Martin County including north to
Jonathan Dickinson Park including Jupiter Hills, Rolling Hills and a part of southern Jupiter
Island; and, the entire Town of Jupiter Inlet Colony, a peninsula lying adjacent to the
Intracoastal Waterway, Jupiter Inlet and Atlantic Ocean. The Village service area is not
expected to expand its physical boundaries through the Year 2030. The Village service area
boundaries are indicated in Figure 2-1.
3.1.2 Climate
Due to its proximity to the Atlantic Ocean in South Florida, the climate in the Village of
Tequesta is humid with warm temperatures characteristic of long tropical summers and
mild winters. According to climate data provided by the National Meteorological and
Hydrological Services ECMWF data, the average annual temperature is 74.9°F. During
extended periods from the month of June through the month of September, daytime
temperatures often exceed 90°F. Winters are generally short and mild with January
generally the coldest month with an average daily temperature of 66.6°F.
The average rainfall in the Village is approximately 44 inches. Approximately 60% of the
total rainfall occurs during the months of June through September.
From June to September, daily thunderstorms with moderately high winds are likely to
occur. The hurricane season begins in June and concludes in November and heavy rainfall
and high winds can be expected during this time period.
3.1.3 Topography and Drainage
The topography in the service area ranges from sea level to 10 feet. Higher elevations can
be found as you move inland from the areas located adjacent to the surrounding waters.
Figure 3-1 depicts the topography data for the Village of Tequesta service area. Surface
water drains to adjacent waterways with the flow generally from the west to the east except
in those areas adjacent to water bodies.

3.1.4 Geology, Soils and Physiography
Most of the planning areas terrain is flat and low lying. According to the USDA Soil
Conservation Service:
"St. Lucie -Urban Land -Paola Association: Nearly level to sloping, excessively drained
soils that are sandy throughout; mostly in urban use. This association is on the mainland
along the coast. It is made up of low ridges and knolls that are part of the coastal ridge.
The natural vegetation is sand pine, scrub oak, and undergrowth of saw -palmetto,
rosemary, cacti, and native grasses. This association makes up about 3 percent of the
survey area. It is about 58 percent St. Lucie soils and Urban land, 7 percent Paola soils,
and 35 percent minor soils. St. Lucie soils are nearly level to sloping and are excessively
drained. Typically, they have a thin surface layer of gray sand. Below that is white sand
that extends to a depth of more than 80 inches. Urban land is made up of areas where
streets, build-ings, parking lots, and other structures cover more than 75 percent of the
land. In residential areas, streets, houses, sidewalks, and other structures cover 25 to 50
percent of the land. Paola soils are nearly level to sloping and are excessively drained.
Typically, they have a thin surface layer of dark gray sand and a subsurface layer of
white sand. The subsoil is strong brown sand in the upper part and light yellowish -
brown sand in the lower part. The minor soils in this association are Pomello,
Im-mokalee, Basinger, and Placid soils. Some of these have been graded or filled in for
urban use. Much of this association is in urban use, but some large areas in the northern
part are in native vegeta-tion. Farming is not important because of the rapid urban
expansion and because the major soils are not suited or poorly suited to most crops.
Limitations are slight for many urban uses. The major soils have severe limitations for
structures designed for holding water, disposing of refuse material, and recreation
development."
The soils characteristics for the planning area, as provided from the USDA Soil
Conservation Service, Soil Survey of Palm Beach County, December 1978, are as
described above and summarized as follows.
Throughout the planning area, nearly level to gently sloping, excessively drained
soils exist. These soils are typically sandy throughout. The majority of the soils are
St. Lucie soils, 58 percent, with 7 percent Paola soils and 35 percent soils of minor
extent. St. Lucie soils are excessively drained. The surface layer is a thin layer of
gray sand, the subsurface layer is mostly white sand to a depth of 80 inches or more.
Paola soils are also excessively drained and consist of a thin surface layer of dark
gray sand followed by a subsurface layer of white sand. The subsoil is strong brown
sand in the upper layers and light yellowish -brown in the lower layers.

3.1.5 Surface and Ground Water Hydrology, Quality and Uses
3.1.5.1. Surface and Ground Water Hydrology
Figure 3-2 illustrates the surface water features located within the
planning area. The Intracoastal waterway is located within the planning
area and serves as the marine highway for boat traffic travelling through
the Village of Tequesta on their way north or south. A portion of the
planning area is also adjacent to the Loxahatchee River — Lake Worth
Creek Aquatic Preserve.
3.1.5.2 Surface and Ground Water Quality and Uses
The Surficial Aquifer and Upper Floridan Aquifer lies beneath the
planning area. The water quality in both aquifers is good and their
primary use in the planning area is potable water supply. The adjacent
surface water is the Intracoastal Waterway (ICW) and the Atlantic
Ocean. Both are saline water bodes, although the ICW is typically a lower
salinity than the ocean due to its interaction with groundwater and
stormwater. Much of the ground water in the planning area is Class G-
11 (potable water use).
A portion of the service area is also within the Loxahatchee River
Pollutant Reduction Plan, which is a voluntary pollutant reduction plan
in which stakeholders in the Loxahatchee River area have provided
nutrient management activities to make progress towards achieving the
area's water quality criteria set for nutrients.
3.1.6 Source Water Protection
The Village's 2018 Comprehensive Plan, Future Land Use Policy 1.1.3 states
"Coordinate and support Palm Beach County and Martin County in the protection
of potable water well fields, and in the implementation of applicable well field
protection programs." and Policy 1.4.7 states "The Village shall protect potable
water wellfields by allowing only the land uses encompassed within the wellfield
drawdown zones of influence shown on the Future Land Use map".
Utilities Policy 1.1.5 states "The Village shall continue to protect existing wellfields,
surface or subsurface storage facilities, control structures, water treatment plants
and transmission infrastructure from increased coastal flooding, considering sea
level rise, saltwater intrusion, and other potential future impacts, and plan for
infrastructure replacement and relocation as needed to maintain the Village's
potable water LOS" and Policy 1.2.2 states "Future wells should be located where

the potential for saltwater intrusion into the surficial aquifer and existing well fields
in periods of drought is minimized."
Additionally, The Village's Code of Ordinances, Chapter SO — Natural Resource
Protection, Article V. Wellfield Protection adopts the Palm Beach County Wellfield
Protection Ordinance.
The proposed projects are not located near the Village's wellfield as identified in
Figure 3-3 and will not interfere with the Village's water supply source water
protection. Appendix B contains a copy of the Palm Beach County Wellfield
Protection Ordinance.
3.1.7 Environmentally Sensitive Areas or Features
3.1.7.1 Wetlands
According to the U.S. Department of the Interior National Wetland
Inventory Map, numerous freshwater wetlands border surface water
bodies that drawing the service area. Figure 3-2 presents wetlands
identified in the National Wetland Inventory. There will be no wetland
impacts associated with the Village of Tequesta water system improvement
project.
3.1.7.2 Environmentally Sensitive Lands
The water system improvements will be constructed either within the
public road Right -of -Way or at the water treatment plant site. There are
no environmentally sensitive lands within the project area.
3.1.7.3 Plant and Animal Communities (Endangered Species)
According to the Palm Beach County Soil Survey, wildlife habitat has already
been impacted with development in the urbanized areas near the coast
such as the Village of Tequesta. The most extensive areas of good habitat
are in the undeveloped rangeland and the ocean beaches which are used
extensively for nesting by endangered and threatened sea turtles and
mangrove areas in the Intracoastal Waterway which are valuable as
rookery and roosting areas for wading birds and pelicans.
The water system improvements project will be within the limits of public
road Right -of -Ways within the Village of Tequesta service area or at the
water treatment plant site and therefore no endangered or threatened
species of animals or vegetation will be impacted with this project.

3.1.7.4 Archaeological and Historical Sites
Figure 3-4 identifies the historical and archaeological sites recorded in the
Florida Master Site File (Florida Division of Historical Resources) within the
Village service area. As noted previously, the water system improvements
will be constructed within the limits of public road Right -of -Way or at the
water treatment plant site. Although there are historical structures located
within the project area, none of these resources will be impacted by the
Village of Tequesta water system improvement project. Construction is
limited to the road right-of-way and water treatment plant site and all of
the listed resources are located across the outside the limits of
construction.
3.1.8 Floodplain
Flood zones for the project areas are presented in Figure 3-5. The areas in which
the proposed infrastructure improvements are to be constructed are located in
Zones X. A, and AE. The Flood Insurance Rate Map (FIRM) defines Zone X as an 0.2%
Annual Chance Flood Hazard area, areas of 1% annual chance flood with average
depth less than one foot or with drainage areas of less than one square mile. Zone
A is an area with a 1% annual chance of flooding and a 26% chance of flooding over
the life of a 30-year mortgage. Because detailed analyses are not performed for
such areas; no depths or base flood elevations are shown within these zones. Zone
AE is designed as the 100-year floodplain where base flood elevations have been
determined. The construction of the Village of Tequesta water system
improvements will occur within the limits of the public road Right -of -Way or at the
water treatment plant site and will not create any impact on the existing floodplain
boundaries as the surface elevation will not be altered with the proposed projects.
3.1.9 Air Quality
According to the Florida Department of Environmental Protection, Florida Air
Quality System (FLAQS) website, the Village of Tequesta's water service area is an
"attainment" area with respect to the National Ambient Air Quality Standards.
The construction of the Village of Tequesta water system improvements will not
create any impact on the existing Village of Tequesta air quality.
3.2 Socio-economic Conditions

3.2.2 Land Use and Development
Future land use is established in the Comprehensive Plans for the Village of
Tequesta, and is depicted in the Future Land Use Maps, Figure 3-6. Areas within
the Village consist of commercial, residential, recreation and open space,
conservation, and limited areas of public buildings and grounds. The central area
of the Village is a mix of commercial and residential. Heading east, the
predominant land use is mixed use and commercial. Along the western city limits,
uses are residential with the golf course in the center of this area.
3.3 Water Supply, Treatment and Transmission/Distribution System
3.3.1 Description of the Existing Water System
The major components of the Village of Tequesta water system are summarized in
this section. These facilities include the potable water treatment plant (WTP),
storage facilities, high service pumping system, and the transmission and
distribution system.
The Village's main raw water supply source is the Surficial and the Upper Floridan
Aquifer. Raw water is sourced from fourteen groundwater wells scattered
throughout the service area. There are ten surficial aquifer wells (seven on the
Eastern Peninsula of the Village and three on the Western Peninsula) and four
Floridan aquifer wells all located on the Eastern Peninsula. The Village's current
Water Use Permit allows for one additional surficial and one additional Floridan
well to be constructed, if required.
3.3.2 Water Treatment Plant
The Water Treatment Plant is comprised of two parallel treatment processes, a 2.7
MGD sand filter process and 3.6 MGD reverse osmosis plant. The sand filter process
is comprised of six carbon steel filter vessels, a surge tank, an air scour system,

ammonia feed facilities, three transfer pumps, and associated piping, valves,
controls, and instrumentation. The reverse osmosis process is comprised of three
cartridge filters, three high-pressure membrane feed pumps, three reverse osmosis
trains, two degasifier and air scrubber systems, a clearwell (where blending of
effluent from the filter process and reverse osmosis process occur), three transfer
pumps, bulk chemical storage and feed facilities, and associated piping, valves,
controls, instrumentation and emergency power equipment. Under normal
conditions, treated water from storage tanks at the water treatment plant is
pumped to the distribution system through the high service pumps.
3.3.3 Water Treatment Plant Storage
Blended finished water is stored in two ground storage tanks located at the WTP
with capacities of 0.75 million gallons (MG) and 2.0 MG. From there, the finished
water is delivered to the distribution system by seven high -service pumps.
3.3.4 Water Treatment Plant High Service Pumps
Finished water is pumped to the distribution system with the high service
pumping system consisting of two high service pump stations for a total of seven
pumps. The four (4) high service pumps (Pumps 1-4) for the filter plant are all
equipped with a 6.99-in diameter impeller and 40 hp motors. The remaining (3)
pumps are located in the reverse osmosis building and are all horizontal split case
pumps. Pumps 5 and 6 are equipped with 13-inch diameter impellers with 125 hp
motors while pump 7 is equipped with a 11.96-inch impeller and 75 hp motor.
Pumps 5 and 7 are variable speed and all pumps utilize a suction and discharge
16-inch isolation butterfly valve and 16-inch silent check valve on discharge.
Under normal operations, both high service pump stations draw from the ground
storage tanks.
3.3.5 Transmission and Distribution Network
The pipe network is comprised of transmission mains larger than 8-inches in
diameter, and smaller diameter distribution mains (2- through 8-inches in
diameter). The oldest portions of the Village's distribution system were installed
in the 1950s and the system has been expanded multiple times to accommodate
growth. The piping network that comprises the distribution system include
asbestos cement (AC), ductile iron (DI), and polyvinyl chloride (PVC).
Approximately 153,000 linear feet of portions of the system (installed between
1950 — 1970) are constructed with AC pipe. The more recent sections of the
system have been constructed with PVC and DI pipe.
The Village has three connections with adjacent Public Water Systems to provide
19

Agenda Item #16.
alternate sources of potable water in emergency situations. Two emergency
interconnects are with the Town of Jupiter and the third is with South Martin
Regional Utility which is owned by the Town of Jupiter Island. All interconnects
remain closed during normal operations and are opened in the event of a loss of
water supply or pressure within any of the water systems.
3.3.6 Present and Historical Water Usage
The future total water demand for the system was developed and documented in
the Village's 2018 Comprehensive Plan. The projected demands from this report
are summarized in Table 3-2. As shown in this table, the average annual daily
(AAD) finished water demand for 2025 is expected to be 3.36 MGD.

The projected daily potable water necessary to serve the Village's future demands ranges
from 3.36 million gallons per day (MGD) to 4.17 MGD. Based on these projections, neither
the average daily demand nor the maximum daily demands are anticipated to exceed the
current permitted combined WTP capacity of 6.3 MGD within the planning period.
3.3.7 Water Conservation
The Village currently has in effect a multi -element water conservation program.
This program has been in place over most of the previous Water Use Permit period
(over 20years). Moreover, the Village of Tequesta instituted a water conservation
rate structuring program that charged incrementally higher rates for higher usage
of the potable water system. The improvement since 2000 has been materially
impacted by the implementation of this water conservation rate structuring. It is
20
Page 215 of 222
Agenda Item #16.
anticipated that the success of the program will continue, and the Village is
committed to the vigorous pursuit of all efforts toward water conservation.
The Village continues to implement a leak detection program. The program is based
on the concept of comparing the volume of water produced for consumption and
the volume billed. This calculation is performed monthly, and the yearly results are
submitted to the SFWMD. Action levels have been established. As part of the
program and to improve the accuracy of the calculations, the Village has adopted a
residential and commercial meter replacement program.
The Village has adopted and continues to implement various regulations that
improve water conservation. The Village has adopted water protection and
conservation measures in Article VI.
Water Protection and Conservation of Chapter 50, Natural Resources Protection in
the Village Code of Ordinances. Specifically, Article VI, Sec. 50-187 requires the use
of low volume plumbing fixtures and Article VI, Sec.50-189 requires rain sensor
overrides for all irrigation systems and recognizes SFWMD criteria related to
limiting irrigation hours for lawns and ornamentals.
The use of reclaimed water for irrigation purposes is an effective water
conservation measure. The Village does not own or operate a wastewater
treatment facility and, as such, does not manufacture reclaimed water. The Village,
however, is located within the LRD service area, and the LRD does produce
reclaimed water. The Village continues to work with the LRD to encourage its use.
There are customers within the Village water service area that currently use
reclaimed water for these purposes.
The Village makes water conservation literature available to all customers. In
addition, the Village improves public awareness of water conservation through
distribution of related information in water bill messages, the Village Newsletter
and other literature displayed in information racks at Village buildings. There are
some water conservation related issues addressed in the Coastal Management
element of the Village's Comprehensive Plan which are addressed in the Coastal
Management.
3.3.8 Performance of Existing Water System
The Village of Tequesta water distribution system, although aging, continues to
function adequately. The large booster pumps at the Village's water treatment
plant perform well and the water treatment plant has undergone significant
renovations over the years and is more than adequate to treat the projected
demand permitted under the water use permit from the South Florida Water
Management District.
21
Page 216 of 222
Agenda Item #16.
3.3.9 Service Population and Water Demand Projection
The water demand for 2025 is developed based upon the population projection and
per capita demand of 247 gallons per capita. Table 3-2 listed above, presents the
projected water demands from 2010 to 2030.
3.4 Managerial capacity
The Village of Tequesta Utilities Department has the responsibility and authority to operate
and maintain the water system. Department staff has the capability and capacity to
maintain and operate the Village's water system. The Village's water system is continuously
operated in shifts and repairs and rehabilitation of the water mains due to broken pipes and
joints are periodically conducted by Department staff. After hours repairs and maintenance
are conducted with night and weekend utility crews.
Routine water analyses are performed by Utilities Department staff in the Village's
laboratory. Monitoring of the water system is accomplished with SCADA.

Agenda Item #16.
Chapter 4.0 -Alternatives Analysis
4.1 General
The Village of Tequesta Water System Improvements — Phase I project has three primary
alternatives for both the water treatment plant upgrades and the water distribution system
improvements:
Water Treatment Plant Upgrades:
1. No Action.
2. Construct new water treatment facility.
3. Provide various process efficiency and automation upgrades throughout the
facility.
Water Distribution System Upgrades:
1. No Action.
2. Replace in -kind with same material
3. Replace with PVC, HDPE, or Ductile Iron Pipe
4.2 Cost-effectiveness
The cost effectiveness of the project was evaluated based on capital investment, and
operation and maintenance costs. However, the benefit of these projects outweighs the
capital costs as they provide safe and reliable means of drinking water to the Village
customers. Appendix A contains a detailed cost calculation of the selected alternative.
4.3 Water Treatment Plant Upgrades
4.3.1 Alternative #1: No Action
Under this alternative, the Village of Tequesta would not perform any of the
recommended process efficiency and process automation upgrades to the water
treatment facility. As this does not address the issues of the treatment components
and communications systems not working at their optimum efficiency, different
control systems hardware, and need for automation and control over the treatment
system, this alternative is not deemed not viable and hence was rejected.
4.3.2 Alternative #2: Construct New Water Treatment Facility
The capital costs to construct a new 6.3 million gallon per day water treatment
facility would be upwards of $50 million. Due to the excessive capital cost this
option was rejected.
23
Page 218 of 222
Agenda Item #16.
4.3.3 Provide various process efficiency and automation upgrades throughout the
facility.
This alternative involves various proposed water treatment plant upgrades
including process efficiency and process automation upgrades in order to provide
reliable drinking water to the Village customers. The proposed improvements are
detailed in the Process Efficiency and Automation Technical Memorandum
provided under Appendix C. As this alternative addresses the issues of the
treatment components and communications systems not working at their optimum
efficiency, different control systems hardware, and need for automation and
control over the treatment system with cost-effective solutions, this alternative
was selected.
4.4 Water Distribution System Upgrades
4.3.1 No Action
Under this alternative, the existing mains will continue to serve the distribution
network in the Village of Tequesta. The age and condition of the existing AC
pipelines will continue to have various water main breaks throughout the pipe
network. The system will not be a reliable source of potable drinking water. This
alternative is not viable and hence was rejected.
4.3.2 Replace in -kind with same material
This alternative involves replacing the identified water mains with the same pipe
size and materials of the existing system. The existing mains are primarily asbestos
cement and are susceptible to main breaks, and frequent failures and furthermore,
the material is no longer produced. Therefore, this alternative is not viable and
hence was rejected.
4.3.3 Replace with PVC, HDPE, or Ductile Iron Pipe
This alternative involves replacing the identified water mains with 4-inch or larger
polyvinyl chloride (PVC), high density polyethylene (HDPE), or ductile iron mains.
This alternative will improve the capacity of the existing distribution network that
feeds the Village of Tequesta and will provide necessary fire flow needed for the
community. The route of this alternative will be in the same right-of-way as the
existing mains and will not involve any land acquisition or easements. There are no
adverse environmental impacts expected as a result of the implementation of this
alternative. This alternative was selected.
