WASTEWATER MASTER PLAN UPDATE (TA No. 23-165)
The City of Tamarac (City) completed their Wastewater Master Plan in 2013. The City has requested
that Tetra Tech provide this proposal to update the Wastewater Master Plan. The City's
wastewater infrastructure consists of gravity sewers, lift stations, and force mains. Wastewater is
transmitted through force mains to Broward County and the City of Fort Lauderdale for treatment and
disposal. The City does not receive nor utilize reclaimed water.
The existing wastewater infrastructure consists of the following:
• 160 miles of gravity sewers ranging in diameter between 8-inches and 12-inches,
• 96 lift stations (18 top well mounts, 70 submersibles, 8 private systems), and
• 33 miles of force mains ranging in diameter between 1-1/4 to 30 inches.
This master plan will address the rehabilitation and capacity improvements for the gravity sewers, lift
stations, and force mains. The Tasks within the proposal are arranged to correspond with the sections to
be updated (i.e. Task 1 Section 1 Update), followed by other tasks which do not correspond to specific
sections in the Wastewater Master Plan Update (WWMPU).
TASK 1— SECTION 1 UPDATES
Tetra Tech will utilize pdf files from the previous WWMP to create Section 1 Introduction of the WWMPU.
Data will be collected related to the:
• purpose,
• background,
• service area and customer base, and
• overview of existing wastewater system.
Supporting tables and figures will be developed for Section 1, along with updating of the section.
TASK 2 — SECTION 2 WASTEWATER GOALS, STRATEGIES, AND LEVEL OF SERVICE
Tetra Tech will utilize pdf files from the previous WWMP to create and update Section 2 Wastewater
Goals, Strategies, and Level of Service of the WWMPU. Data will be collected related to the:
• historical and future population projections
• historical wastewater flows
• planned redevelopment projects
• traffic analysis zones with the City,
• lift station basins
• projected flows by lift station service area
• wastewater system goals and level of service

Tt #BP Gen Tamarac -1- 04/22/23
• regulatory requirements
• large user wastewater agreements,
Supporting tables and figures will be developed for Section 2, along with updating of the section.
Regulatory Review
Tetra Tech will perform a review of regulations pertinent to the City's collection system. This includes
Florida Department of Environmental Protection (FDEP) wastewater rules such as the 62-600 series of
Florida Administrative Code (F.A.C.). This review will also include a review of sanitary sewer overflows
and onsite sewage treatment and disposal systems (OSTDS) related rules or rule sections that could affect
the City's wastewater facilities.
Numerous wastewater rules have been in the rule development process since 2020 as a result of the 2020
Florida Legislative Session. Tetra Tech will also review any draft changes to wastewater related rules that
are in the rule development process. Finally, Tetra Tech will also track and review any legislation related
to wastewater collection system rules proposed as part of the 2021 Legislative Session. The regulatory
review will be summarized in a Technical Memorandum and incorporated into the Master Plan.
TASK 3 — SECTION 3 INVENTORY AND ASSESSMENT OF EXISITNG WASTEWATER SYSTEM
Tetra Tech will utilize pdf files from the previous WWMP to create and update Section 3 Inventory and
Assessment of Existing Wastewater System of the WWMPU. Data collection listed in Task 2 will aide in
the updates needed for Section 3. Other information to update the inventory and assessment will include:
• new lift stations added to the City's system,
• rehabilitated lifts stations,
• new force mains added to the City's system,
• other pertinent information.
Supporting tables and figures will be developed for Section 3, along with updating of the section. An
updated inventory of the City's gravity sewers, lift stations, and force mains will be developed. A desktop
condition assessment program of the City's force mains will be developed, as outlined in the subsequent
paragraphs, utilizing processes developed by the EPA or other sources. The City has implemented an
Inflow and Infiltration Abatement Program. The results of this program will be summarized in this Section.
A lift station assessment and rehabilitation program will also be developed and will include the following
items:
Lift Station Drawdown Testing
Tetra Tech will perform drawdown testing at critical lift stations with the City's assistance to verify that
the pump is operating near its pump curve if the flow and discharge pressure are not otherwise recorded.
With drawdown testing on manifolded lift stations, Tetra Tech will need input from the City confirming
stations are operating at the same time. Up to 12 lift stations within the City's collection system will be
tested. Tetra Tech will coordinate with the City to develop a testing plan and select stations most
beneficial for the hydraulic modelling effort. Drawdown testing will include measurements of the wet
well diameter, depth, and operating levels. Drawdown tests will be performed on each pump at the
station. Preliminary results will be calculated in the field and compared against pump curves to confirm
acceptable test results.

Linear Assets — Risk Assessment
Rating and Prioritization Criteria:
Tetra Tech will develop a proposed likelihood and consequence of failure rating criteria for use in the
master plan. The proposed criteria will be submitted for City review and approval prior to the risk
assessment analysis. The rating criteria will be used to define corrective actions and prioritize
rehabilitation or replacement of the force mains. Condition or likelihood of failure criteria will be
developed to leverage the available data through GIS and other sources such as pipe age, materials,
maintenance records and interviews with operations and maintenance staff. Consequence of failure
criteria will be based on asset and geospatial characteristics such as pipe size, number of upstream lift
station, proximity to major roads, water bodies and environmentally sensitive areas.
Tetra Tech will utilize the criteria to characterize the risk of the force main system elements and define
the necessary actions to be taken to reduce the overall risk.
Workshop:
Tetra Tech will conduct a workshop detailing the results and outcomes of the force main risk analysis.
Tetra Tech will prepare the agenda and presentation materials ahead of the workshop and provide
minutes summarizing the workshop discussion.
Draft Risk Analysis Technical Memorandum Submittal and Review:
Tetra Tech will prepare a Draft Technical Memorandum that presents the data analysis, maps, and
projections described under the force main risk analysis above. Tetra Tech will submit an electronic copy
of the documents to the City for review and comment. The memorandum will take the form of sections
that will ultimately be included in the Master Plan.
Tetra Tech will receive Draft comments from the City and enter them into a revisions log for purposes of
tracking comments and their resolution. Tetra Tech will conduct a meeting to review and discuss City
comments. Tetra Tech will record and distribute meeting minutes of the meeting.
Tetra Tech will incorporate the City's review comments into the Technical Memorandum and submit one
electronic copy of the final Technical Memorandum.
Lift Station Assessment and Rehabilitation Program
The City is currently implementing a lift station assessment and rehabilitation program, where it is
converting lift stations with above ground pumps to submersible lift stations and rehabilitating
submersible lift stations. The City desires that the wastewater master plan contain a summary of this
program. The information from this program will be provided to Tetra Tech for summary in the master
plan. The information to be provided by the City includes rehabilitation components and budgeted costs.
The program received will be summarized in Section 3 and included into the master plan's Capital
ImprovementProgram.
TASK 4 — SECTION 4 EVALUATION OF FUTURE WASTEWATER SYSTEM REQUIREMENTS
Tetra Tech will update Section 4 Evaluation of Future Wastewater System Requirements of the WWMPU.
Data will be collected from the City related to the:
• planned redevelopment projects,
• lift station basins,
• lift station run times,
Wastewater Master Plan Update 042223.docx TETRATECH
Tt #BP Gen Tamarac -3- 04/22/23
• Existing GIS shape files and data base of the systems,
• lift station pump curves,
• Selected SCADA data as available,
• Record drawings for recent projects not covered in the GIS information,
• Parcel boundaries,
• Potential changes in FEMA Flood Maps,
• Existing hydraulic models and master plans,
• Comprehensive plans for City of Tamarac,
• Existing and future land use maps for City of Tamarac,
• Current permits associated with the systems,
• Potable water and wastewater customer data,
• recent and anticipated changes in Broward County codes, and
• other information.
Tetra Tech will analyze existing (2022) population data and wastewater flows for the purpose of
developing both existing system hydraulic models to simulate the wastewater lift stations and force main
systems operation for 2022 and future planning horizons. An existing system hydraulic model will be
developed for the lift station and force main network, utilizing the GIS data after being updated with
recent projects not in the GIS. The GIS data will be processed for model import. The model will include
the force mains and not the gravity system or lift stations and force mains discharging to gravity sewers.
Wastewater flows from 2022 will be disaggregated to the existing lift stations. The existing model will be
calibrated utilizing the collected pressure data. Hydraulic modeling can be done using InfoWater or
WaterGEMS modeling software, whichever is preferred.
The existing and future system model scenarios will be run after calibration to identify any pumping,
pressure, or velocity deficiencies. The model scenarios will simulate steady-state, peak -flow conditions.
Capital improvement Projects to remedy existing deficiencies will be identified, through hydraulic
modeling or other methods. In addition, pump run times will be evaluated for the City's lift stations to
identify any pumps exceeding run time standards. Lift stations exceeding the run time standards will be
considered for capacity upgrades.
Future population projections will be utilized to project wastewater flows through 2045. Wastewater
flows will be disaggregated to existing and future lift stations. Future planned redevelopment projects
will also be included in the wastewater projections. Capital improvement projects to meet future
capacities will be identified for the following planning horizons:
• 2030 (existing plus known changes)
• 2040
• 2050
Tetra Tech will summarize existing and proposed regulatory requirements that will affect the wastewater
collection and transmission systems. Regulatory impacts affecting the capital improvement projects will
be highlighted and their implementations considered in the planning process.
Tetra Tech will perform two (2) force main redundancy evaluations, one for each system discharging to
Broward County and City of Fort Lauderdale wastewater systems. The purpose of these evaluations will
be to identify routing, size, and costs for redundant force mains. The City will use this information to
determine and plan redundant force mains, if desired.

Tt #BP Gen Tamarac -4- 04/22/23
Lift Station and Transmission Asset Improvements
Tetra Tech will define projects for upgrades and improvements to the transmission systems to meet future
growth needs as determined in the modeling scenarios above. Recommendations will include capital and
operational modifications to meet demands, improve hydraulic efficiency, and system reliability within
the transmission systems. The linear assets will cover:
• Capacity limitations identified in the hydraulic modeling results.
• Capacity increases due to growth and increases in wastewater flow.
• Condition assessment and consequence analysis of the system linear assets.
• Consideration of planned roadway improvements and their potential effect on pipeline assets.
• Interconnection between WRF basins for improved reliability and resiliency.
• Other goals and strategic opportunities identified through the master planning process.
TASK 5 — SECTION 5 REPORT SUMMARY AND CAPITAL IMPROVEMENT PROGRAM
Tetra Tech will update Section 5 Report Summary and Capital Improvement Program of the WWMPU.
The Capital Improvement Program will be developed, in line with the evaluated planning horizon and
timeframes. Each project will be identified with a title, description, purpose, implementation year, and
cost. The Capital Plan will include costs and implementation schedules. Costs will be developed to AACE
Class V standards, for each project.
A Draft Wastewater Master Plan Update will be developed and submitted to the City for review and
comments. The appendices supporting the WWMPU will also be assembled with the draft submittal.
Comments will be combined by the City's project manager and submitted to Tetra Tech. Tetra Tech will
address each comment, develop a comment and response log, and submit a final WWMPU to the City.
TASK 6 — PROJECT MANAGEMENT, SITE VISITS, AND MEETINGS
Tetra Tech will provide monthly project status reports and conduct monthly progress meetings. An
agenda and minutes will be prepared for each meeting. Tetra Tech will also visit various wastewater
infrastructure sites, including lift stations and connection points, over the course of two days to gather
site specific information and familiarity.
