I. Introduction:

The purpose of the City of Tampa 10-Year Water Supply Facilities Work Plan (Work Plan) is to

comply with the statutory requirements for water supply planning, specifically Section 163.3177,

Florida Statutes, which requires that comprehensive plans are to be updated within 18 months of

when a Water Management District’s Governing Board approves a Regional Water Supply Plan.

The Southwest Florida Water Management District (SWFWMD) approved an updated Regional

Water Supply Plan (RWSP) on November 17, 2015.

Listed below is a summary of statutory requirements, according to the Department of Economic

Opportunity (DEO) publication A Guide to the Preparation of the Water Supply Facilities Work Plan:

1. Coordinate appropriate aspects of the comprehensive plan with the appropriate Water

Management District’s RWSP (s.163.3177(4)(a), Florida Statutes).

2. Revise the Potable Water Element considering the RWSP of the appropriate water

management district (s. 163.3177(6)(c), Florida Statutes).

3. Revise the Potable Water Element to include a Water Supply Facilities Work Plan for at

least a 10-year planning period, addressing the water supply facilities necessary to serve existing

and new development and for which the local government is responsible (s. 163.3177(6)(c),

Florida Statutes).

4. 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 or, in the

absence of an approved RWSP, the district water management plan (s. 163.3177(6)(d), Florida

Statutes).

5. Revise the Intergovernmental Coordination Element to ensure coordination of the

comprehensive plan with the applicable RWSP (s. 163.3177(6)(h)1, Florida Statutes).

6. During adoption of Evaluation and Appraisal Report based amendments, revise the

Potable Water Element to include the Work Plan (s.163.3191(2), Florida Statues.

In summary, the Work Plan and related goals, objectives and policies must address the

development of traditional and alternative water supplies, as well as conservation and reuse

programs to serve existing and potential increased demand for at least a 10-year planning period.

The Work Plan must also be coordinated with SWFWMD’s 2015 RWSP. This Work Plan has been

developed in accordance with these requirements and serves as data and analysis for the Water

Supply Facilities Work Plan Table, which will be included in the Imagine 2040 City of Tampa Comprehensive Plan.

II. Coordination Effort

Planning Commission staff worked with the City of Tampa Water Department staff, Tampa Bay

Water staff and SWFWMD staff to gather and analyze the appropriate data for preparation of this

Work Plan. Information in this Work Plan was provided by all three groups, and significant

coordination occurred throughout the planning process.

2

III. Existing Conditions

A. Service Areas

The City of Tampa owns, operates and maintains a central potable treatment and distribution

system within its corporate limits, as well as beyond its jurisdictional boundaries in unincorporated

Hillsborough County and a very small portion of Temple Terrace. The city also owns, operates

and maintains a reclaimed water system primarily in South Tampa, with extensions to the

Westshore/Tampa International Airport area and to the McKay Bay Waste to Energy Facility. A

map of the City’s potable and reclaimed service area is included as Exhibit A.

B. Water Use Permit and Tampa Bay Water Information The City has a Water Use Permit (WUP) (#2062.006) from SWFWMD for withdrawal of 82 mgd (annual average) from the Hillsborough River Reservoir. The City’s permit expires in 2024, within the planning horizon of this Work Plan. Per the SWFWMD Water Use Permit Evaluation Manager, public supply permit renewals are typically not received until the year prior to permit expiration. The City is a member of Tampa Bay Water, which is a regional water supply authority with an unequivocal obligation to provide potable drinking water to its six member governments. The relationship between the City and Tampa Bay Water is governed by the Amended and Restated Interlocal Agreement (1998) and Master Water Supply Contract. The Interlocal Agreement states that Tampa Bay Water is obligated to meet the demand that the City cannot meet through its surface water sources. This obligation is accomplished by providing the City water at two points of connections, Harney Augmentation pump station and Morris Bridge pump station. There is also an emergency interconnection located at Tampa Bay Water’s regional facility site in which Tampa Bay Water can provide potable drinking water to the City under certain emergency conditions. Tampa Bay Water is required to update its Long-term Master Water Plan every five years. The current plan was approved in 2013 and provided water demand projections out to the year 2035 (Exhibit B). Tampa Bay Water is currently updating its existing plan which extends the planning horizon to 2040. The updated plan will include long-term demand projections to the year 2040 and potential new water supply projects, and will be presented to Tampa Bay Water’s Board in December 2018. Additional details on the active project concepts and updated status of projects can be found in Exhibit C, the letter from Tampa Bay Water. This letter also confirms sufficient supplies to meet the City’s future water needs, above its permitted quantities of 82 mgd.

C. City Potable Water Facilities The City maintains potable water treatment, pumping and storage infrastructure. A map of major facilities is included with this report as Exhibit A. The following information is an excerpt from the City Water Department’s 2016 Annual Report: Treatment Facilities The David L. Tippin Water Treatment Facility (DLTWTF) utilizes a process of coagulation, flocculation, sedimentation, ozonation, filtration and chloramination to convert raw water into drinking water. Pre-disinfection is achieved through the use of ozone. Chlorine and ammonia are added later in the process to provide post-disinfection with chloramines. The City of Tampa Water Department supplements water from DLTWTF with wholesale water as needed. This water is delivered to the City at the Morris Bridge Repump Station from the Tampa Bay Water system.

3

Pumping Facilities A total of 24 pumps are available to pump treated water through the transmission/distribution system. The DLTWTF has eight (8) electrically driven high service pumps, three (3) equipped with variable speed drives, with a total rated capacity of 158 MGD. The Morris Bridge Repump Station has six (6) electrically driven high service pumps, all equipped with variable speed drives, with a total rated capacity of 91 MGD. Emergency generator power is available to operate all of the above pumps. The Northwest Repump Station has three (3) electrically driven pumps with a total rated capacity of 12 MGD. The Interbay Repump Station contains six (6) electrically driven pumps with a total rated capacity of 14 MGD. The West Tampa and Palma Ceia elevated tanks each have one (1) electrically driven pump rated at 7.2 MGD. This provides the City with a pumping capacity of 289.4 MGD. Backup power is provided at the Northwest and Interbay Repump stations sufficient to operate all the pumps. Storage Facilities Storage capacity at the DLTWTF is provided by four underground clearwells with a combined capacity of 20 million gallons. The Morris Bridge Repump Station has two (2) ground storage tanks with a capacity of 5 million gallons each. Two (2) elevated storage tanks provide 3 million gallons (1.5 MG each) and ground storage tanks at the Northwest Repump Station (3 MG) and Interbay Repump Station (5 MG) provide 8 million gallons of storage. This is a total storage capacity of 41 MG. Additionally, the City projects the following information for the future capacity (mgd):

amount plus 40 mgd capacity at the Tampa Bay Water

Morris Bridge interconnect. Tampa Bay Water has an

unequivocal obligation to meet Tampa’s water demands.

D. Alternative Water Supply Facilities – Reclaimed and Aquifer Storage and Recovery

Reclaimed

The City’s Howard F. Curren Advanced Wastewater Treatment Plant treats more than 60 mgd

per day of wastewater. The City’s reclaimed water system delivers highly treated wastewater to

residents and businesses in South Tampa and the Westshore area, as well as Tampa

International Airport and business locations along Boy Scout Blvd. Reclaimed water is also used

by the City to operate Tampa’s McKay Bay Waste to Energy Facility, where 0.6 mgd of reclaimed

water is used for evaporative cooling. This effort provides a 1:1 potable water offset. The CF

Industries’ Tampa Ammonia Terminal also uses warm effluent from Howard F. Curren in a heat

exchange loop.

In 2015, the wastewater treatment plant (WWTP) flow was 64.24 mgd, the reuse flow was 5.26

mgd and the reuse benefit was 4.35 mgd. The five-year average is 59.87 mgd (WWTP flow), 6.31

4

mgd (reuse flow) and 5.10 mgd (reuse benefit). Beneficial reuse does not include most internal

use at treatment plants, sprayfields or RIBs disposal.

Aquifer Storage and Recovery

Due to the City’s flat topography, seasonal rainfall fluctuation and shallow reservoir depth, the

City has difficulty sustaining a water supply storage volume that can meet year-round demand.

ASR is one alternative that is used to minimize the extent that the City relies on regional drinking

water from Tampa Bay Water during peak demand times. The Tampa ASR system stores up to

1 billion gallons of treated water underground and recovers the water during the annual dry

season at a 10 mgd peak rate.

E. Conservation Initiatives

The City has a very strong, multifaceted water conservation program that employs numerous

operational, educational and policy measures. A full description of the City’s conservation

initiatives is listed in Exhibit D (Tampa Water Department 2015-2019 Water Conservation

Program), which is incorporated by reference into this report. These measures include the

following:

1. Operational Measures

Source and finished water, and service connection metering

Fixed interval meter reading

Meter testing, calibration, repairing and replacing

System audit

Distribution system pressure control

Recycled water for filter backwashing at treatment plants

Customer leak notification

Water conservation coordinator – full time staff member

2. Educational and Program Measures

Informative billing and water bill inserts

Plumbing retrofit giveaways to thousands of residential and business customers

Rain sensor distribution program

Commercial pre-rinse spray-valve retrofit program

Industrial, commercial and institutional water-use efficiency evaluation program

Water use surveys

Public information/education program

Plumbing workshops

Customer surveys

3. Policy Measures

Conservation rate structure

Landscape/irrigation ordinance

Stringent restriction enforcement and reduced irrigation hours

Low-volume fixture ordinance

Rain sensor ordinance

Reclaimed water mandatory hookup for irrigation

5

In 2015, the sum of these projects had a cumulative annual savings of .06 mgd and a cumulative

total savings of 2.02 mgd. For additional details, including a breakdown of conservation, please

see Exhibit D.

F. Ongoing Cooperative Funding Initiative Projects

The City has two ongoing Cooperative Funding Initiative (CFI) water supply projects with

SWFWMD, N601 (Hillsborough County/Tampa/Plant City/Temple Terrace Reclaimed Water

Recharge Feasibility Study) and N751 (Tampa Augmentation Project). Details of these projects

are included in Section V and VI.

IV. Future Population and Demand Projections

The City recently analyzed population and demand projections as part of its Potable Water Master

Plan (Master Plan) update. Please see Exhibit E, incorporated by reference into this document,

for a full discussion and comparison of the various population and demand projections

considered.

Ultimately, the demand projection used for the Master Plan was an average of the four sources

available: SWFWMD 2015 projections, Tampa Bay Water 2015 projections, and high and low

projections prepared by the City for Tampa Bay Water. Please see Exhibit E for a comparative

analysis.

For consistency, the City Water Department requested that the same average demand projections

used in the Potable Water Master Plan serve as the demand projections for this Water Supply

Work Plan. These projections have also been included in the City’s Environmental Element.

Table 1: Average Demand Projections

Year Projected Demand (Average)

2015 72.3

2020 77.3

2025 81.0

2030 84.5

Notes and Caveats for Demand Projections

Planning Commission staff is aware of the population and demand projections prepared by

SWFWMD Water Supply Staff as part of the Community Planning Pages, and the ultimate

demand figures in the City’s Work Plan are slightly higher than SWFWMD’s numbers. However,

as the City figure represents an average of the four sources available, it was considered by the

City to be the best available data and requested that it be used in the Work Plan update.

Population and demand projections will have to be provided at the time of WUP renewal and

further discussions between the City and SWFWMD may be necessary at that time. Please note

that the SWFWMD calculations included in Exhibit E utilize the same five-year per capita average

as noted in the Community Planning sheets (113 gpcd).

6

The population projections contained in Exhibit E differ from population projections elsewhere in

the Comprehensive Plan. This is due to the fact that functional population and service area

population (different than municipal population) are used to calculate the future projections.

Comparison of Future Demand and Supply

Interpolating the projections above, at the end of the 10-year planning horizon, the City of Tampa

will have a potable water demand of approximately 83 mgd. This is slightly higher than the

currently permitted quantities of 82 mgd (expiring in 2024) from the Hillsborough River, however,

Tampa Bay Water has the unequivocal obligation to meet the City’s future needs over its current

permitted quantity of 82 mgd. Tampa Bay Water has sufficient supplies existing or planned to

meet the City’s future needs above its current permitted quantity of 82 mgd see (Exhibit C). The

interconnect at Morris Bridge has approximately 40 mgd of capacity in the pipe system. Tampa

Bay Water is obligated to meet the demand that the City cannot meet through its surface water

sources. A letter is included in Exhibit C of this report confirming adequate future water supply.

While future demand can be met by permitted quantities and Tampa Bay Water, the City will

continue to employ multiple reclaimed, conservation and alternative water supply projects and

consider potential options to help reduce/offset future potable demand.

V. Future Project Options - RWSP

As part of the RWSP process, SWFWMD is required to identify water supply options from which

water users in the planning region can choose to meet their individual needs. SWFWMD’s 2015

RWSP identifies several potential future project options for the City of Tampa. Per conversations

with SWFWMD Water Supply Staff, there is no obligation for local governments to implement

these projects, and the costs/benefits are estimates from SWFWMD staff.

The HC/COT Interconnect listed in the RWSP options table is being considered as part of a three-

phase project jointly funded with the Hillsborough County, Plant City and Temple Terrace. The

City of Tampa is only contributing funding for Phases 1 and 2.

7

The phases are:

N471: Phase 1 - A “big picture” modeling study examining the quantities and rough costs

for developing a regional reuse system in Eastern Hillsborough (Completed)

N601: Phase 2 - A more refined study of recharge options to site recharge of 25 mgd of

reclaimed water and examine areas, options, benefits and more refined costs (Ongoing)

N755: Phase 3 - A specific modeling study examining specific options, likely benefits and

preliminary costs for developing recharge options (Proposed – FY 2017 Funding

(Hillsborough County only))

Additionally, a multi-year reclaimed expansion project is funded in the City’s current CIP. This is

limited to expansion of reclaimed water services within the current service area.

VI. Future Cooperative Funding Initiative (CFI) Project

In addition to the N601 project listed in the previous section, the City’s Tampa Augmentation

Project (TAP) (N751) is slated to begin shortly. This project proposes to use highly treated

reclaimed water to recharge the aquifer adjacent to the Tampa Bypass Canal, as well as evaluate

recharging the Avon Park formation with reclaimed water for subsequent recovery from the

Suwannee formation and delivery to the Hillsborough River Reservoir. The feasibility study is

expected to be completed in December 2017.

VII. Future Capital Projects – 10 Year Water Supply Facilities Work Plan

Please see Exhibit F for the 10 Year Water Supply Facilities Work Plan table. This table will also

be adopted in the Potable Water Section.

VIII. Future Quantifiable Savings from Reclaimed and Conservation Projects

Conservation and reclaimed projects will continue to be City strategies to offset future potable use

and reduce future potable demand. Although quantifiable estimates are not available for all future

projects/components of projects, Table 3 lists out the estimated quantifiable future savings.

Additionally, the RWSP project options listed in Section V identify potential future offsets should

the City choose to pursue those options.

Long-Term Master Water Plan 2013 Executive Summary

Tampa Bay Water Page ES-1

Executive Summary

Tampa Bay Water is a regional water supply authority that provides wholesale water for its six Member

governments: Hillsborough, Pasco and Pinellas counties, and the cities of New Port Richey, St.

Petersburg and Tampa.

The Amended and Restated Interlocal Agreement (referred to as the Interlocal Agreement) requires that

the Master Water Plan be updated every five years. Tampa Bay Water was formed in 1998, the first

revision to the Master Water Plan was approved by the board of directors in 2003, the second was

approved by the Board in 2008, and the third revision is required to be completed by the end of 2013.

This document, entitled Long-Term Master Water Plan 2013, has been developed to meet this

requirement and to ensure that Tampa Bay Water meets the unequivocal obligation to provide quality

water to the member governments now and in the future.

A. Section 1 – Introduction and Overview

Tampa Bay Water owns and operates a diversified water supply system. The Agency’s Long-Term

Master Water Plan documents how Tampa Bay Water meets its unequivocal obligation to provide

quality water to the member governments now and in the future. The Amended and Restated Interlocal

Agreement requires that the Long-Term Master Water Plan be updated every five years. Since its

creation in 1998, the Agency has completed three revisions of the Plan. This document, entitled Long-

Term Master Water Plan 2013, is the latest revision.

The objectives of this update are to meet the requirements set forth in the Interlocal Agreement.

According to the Agreement, the five-year update shall, to the extent deemed necessary or advisable by

the board:

Identify current customers, projects and future customers

Review and generally inventory existing Tampa Bay Water facilities

Identify a Capital Improvement Program

Review current Tampa Bay Water permits along with existing and projected regulations

Identify proposed new water supply facilities

Evaluate staffing

Provide hydraulic analysis of both existing and proposed systems

Evaluate present and future sources and treatment requirements in terms of capacity, reliability and economy

Update the list of water supply facilities required to meet the anticipated water quality needs of the member governments for the next twenty years

Long-Term Master Water Plan 2013 Executive Summary

Tampa Bay Water Page ES-2

During the 2008 update, the comprehensive project list was updated and approximately 300 potential

water supply projects were evaluated based on public input and with the advice of the Planning

Advisory Committee. The Tampa Bay Water board approved the update to the Plan in December 2008.

As the result of the update, the Board directed that seven project concepts and three policy planning

areas be further studied. The seven project concepts are: Small Footprint Reverse Osmosis-Pinellas

County; Gulf Coast Seawater Desalination Plant; Tampa Bay Seawater Desalination Plant Expansion;

Thonotosassa Wells; Additional Potable Groundwater from Existing Northern Wells; Surface Water

Expansion Project; and Aquifer Recharge Project. The three policy planning areas were: Source Water

Protection Program; Regional Reclaimed Water Planning Assistance; Demand Management and Water

Use Efficiency. The studies for all three of the policy planning areas have been completed.

Tampa Bay Water’s existing supply should meet the region’s demands for the next decade and the Long-

Term Master Water Plan includes projects to meet the agency’s 20-year planning horizon needs. For the

2013 update, no new water supply facilities are recommended for selection and implementation in the

next five years due to lower regional demand projections. For planning purposes, future project(s)

selection and preparation of water use permits should be based on the supply capacity under average

hydrologic conditions since these projects are in development to meet long-term water supply needs.

The project concepts approved by the board in the 2008 plan update should be studied further over the

next few years to provide information for the board to select the next water supply project(s) for

construction when needed. Tampa Bay Water will continue to implement and enhance its planning and

management activities to address seasonal and severe drought events and long-term future supply needs.

These activities will be conducted along with study of the project concepts in the Long-Term Master

Water Plan to ensure that Tampa Bay Water continues to meet its unequivocal obligation to provide

quality water to the member governments.

B. Section 2 - Existing Facilities Inventory

Tampa Bay Water constructed a regional water delivery system that is comprised of groundwater and

surface water sources, an off-stream storage reservoir, a seawater desalination plant and a collection of

Figure ES-1 Tampa Bay Water Regional Water Supply and Delivery System

Long-Term Master Water Plan 2013 Executive Summary

Tampa Bay Water Page ES-4

Tampa Bay Water has completed adding additional water treatment facilities, an expanded surface water

system, piping and pumping to form a flexible and adaptable water supply system. These sources are

sufficient to meet the region’s drinking water demands over the next decade. Due to slowed regional

demands for drinking water, Tampa Bay Water does not need to select new supply projects during this

update cycle. All potential new water supply projects will be carried into the Master Water Plan

feasibility program and will be evaluated over the next 3-4 years.

C. Section 3 – Capital and Systems Programs

Tampa Bay Water’s Capital and System Programs includes the Capital Improvement Program, Renewal

and Replacement Program, and Energy Management Program.

A. Capital Improvement Program

Tampa Bay Water’s Capital Improvement Program (CIP) is a comprehensive five-year plan of approved

and proposed capital projects. The CIP is updated annually, as the need and timing for specific projects

change. Figure ES-2 shows the process followed for developing the annual update to the Capital

Improvement Program Plan:

Figure ES-2 Capital Improvement Program Annual Update Process

Long-Term Master Water Plan 2013 Executive Summary

C. Energy Management Program

Tampa Bay Water’s Energy Management

Program includes energy efficiency,

conservation and alternative/renewable

energy capital project ideas for our water

supply system. This program follows an

Energy Roadmap, which was developed

to provide a 10-year look at the issues

related to energy consumption at our

facilities. The Energy Roadmap provides

an action plan that sets expectations and

principles along with measurable targets;

it identifies the elements of technology

and energy infrastructure to enhance

financial stability and sustainability; and

it provides a basis to analyze the

relationship between decisions that

affect annual operations and

maintenance capital budgeting. Figure

ES-4 shows the Energy Roadmap.

Tampa Bay Water Page ES-7

Figure ES-4 Energy Program Roadmap

D. Section 4 – Staffing

Tampa Bay Water reviews staffing periodically through formal audits and pay plan and benefit package

reviews. The board approved the latest pay and classification plan for the Agency in April 2013. The

Agency maintains a lean staff of 132 full-time equivalent positions to fulfill the Agency’s mission while

maintaining a fiscally responsible program to serve its member governments.

In April 2011, the board approved an Agency Strategic Plan, which consists of four main goals intended

to guide the Agency in fulfilling the mission of providing clean, safe and reliable water. During 2012, the

Long-Term Master Water Plan 2013 Executive Summary

Tampa Bay Water Page ES-8

Agency underwent a reorganization process in order to meet the goals of the Strategic Plan. Tampa Bay

Water is shifting its focus from building new supplies to maintaining its existing supplies and facilities.

As such, the Agency has reorganized to better reflect the new focus and be more efficient in its

organizational structure. Figure ES-5 shows current organizational structure.

Long-Term Master Water Plan 2013 Executive Summary

Tampa Bay Water Page ES-9

E. Section 5 - Customers and Water Demands

Tampa Bay Water has the unequivocal obligation to meet the water demands of its six member

governments. A major component in developing new potable water supplies is the ability to accurately

determine future demands so that new projects can be implemented when needed, avoiding the risk of

under-or over-estimating when supply is needed. As stated by the American Water Works Association’s

Manual of Water Supply Practices M 50 (2007), a sound water demand forecast allows utilities and regional

suppliers to provide the following:

Adequacy of supply

Optimum facility location and size

Sound transmission and distribution design

Tampa Bay Water provides regional water demand forecasts for its member governments specifically to

project the amount of water supply needed within Tampa Bay Water’s service area. The regional

demand forecasts include the total water demand for the City of Tampa. The Agency’s Long-term

Demand Forecasting models are designed primarily for the purpose of longer-term planning and

forecasting over 20-30 year time horizons. The models provide monthly and annual water demand

forecasts for the seven water demand planning areas (WDPAs) of the six member governments through

the 2035 planning horizon. This demand planning ensures that adequate supply will be made available to

member governments in the future and that supplies are added in such a way as to minimize member

government wholesale water rate impacts.

Seven water demand planning areas are established which reflect the current service area boundaries for

the six member governments. These areas are illustrated in figure ES-6.

Long-Term Master Water Plan 2013 Executive Summary

Tampa Bay Water Page ES-10

Figure ES-6- Tampa Bay Water Member Government Water Demand Planning Areas

Tampa Bay Water updated its Long-Term Demand Forecasting models and developed two long-term

water demand forecasts through 2035. Each model generates demand forecasts based on water demand

planning area specific weather and socioeconomic projections. Annual water demands within Tampa

Bay Water’s service area have been impacted by the economic recession since 2008. Figure ES-7 shows

Tampa Bay Water demand projections by water demand planning area through 2035.

Long-Term Master Water Plan 2013 Executive Summary

Tampa Bay Water Page ES-11

Figure ES-7- Tampa Bay Water Demand Projections by Water Demand Planning Area

Tampa Bay Water will continue to update its demand projections annually to ensure that our

commitment to provide clean, safe and reliable supply to our member governments is met.

F. Section 6 - System Analysis

Tampa Bay Water regularly performs hydraulic analyses for its regional supply and transmission system

to study current system operating conditions and to evaluate plans for projected future operating

conditions. Tampa Bay Water uses a number of tools to perform modeling and analysis. A detailed

description of these models can be found in Section 6 of the Long-Term Master Water Plan.

In 2006, Tampa Bay Water’s system engineer completed the System Analysis Update document, which was

performed to determine regional transmission system improvements. As a result of this analysis, 25

recommendations were made to Tampa Bay Water on overall system improvement. Most of the 25

recommendations have been completed.

The future water supply options identified in the 2008 Long-Term Water Supply Plan were evaluated in

a hydraulic model for the demands projected for the year 2035. The results showed certain hydraulic

Long-Term Master Water Plan 2013 Executive Summary

Tampa Bay Water Page ES-12

limitations in the Morris Bridge Transmission Main, Cypress Bridge Transmission Main, Brandon

Transmission Main and Brandon South Central Connection. The analysis also determined that the

hydraulic limitations would be improved by the addition of new supply capacities downstream of the

Cypress Creek Pump Station at the Lithia Water Treatment Facility. The addition of new supply could

require parallel or increased diameter piping to be installed. As the decision regarding which long-term

water supply projects will be considered for further evaluation and eventual implementation, additional

analyses should be completed to evaluate the need for additional operational flexibility and potential

system operating restrictions.

Tampa Bay Water will update the Tampa Bay Water 2025 System Analysis document completed by Black &

Veatch in 2006, based on the expanded surface water system infrastructure and projected future

demands. The improvements that were recommended from the last analysis that have not been

completed will also be re-evaluated to determine if they are still necessary. The summary of current

System Analysis Recommendations is:

Regional System and Enhanced Surface Water System Surge Models

o Complete the database of system surge features.

o Field verify the equipment and settings.

o Update and run the system surge models to verify that the system has adequate surge

protection.

o Update the surge analysis for any major changes to the system.

Regional Supply and Transmission System and Enhanced Surface Water System Hydraulic

Models

o Evaluate system improvements at the Odessa and US 41 Pump Stations resulting from

an increase in system pressure from Cypress Creek.

o Evaluate options for lowering system pressures in the transmission main between the

High Service pump Station and the Cypress Creek Pump Station.

o Evaluate the benefits of adding finished water storage.

o Update the 2025 Analysis and determine if the previously recommended projects are still

necessary.

o Evaluate long-term water supply options.

Hydraulic Grade Tools (with chemical and electrical cost estimates)

Long-Term Master Water Plan 2013 Executive Summary

Tampa Bay Water Page ES-13

o Project monthly chemical and electrical costs for annual budgeting.

Enhanced Surface Water System Operational Model

o Project supply availability based on projected regional rainfall forecasts.

o Evaluate future surface water system expansion options.

Regional System Performance Model

o Update the analysis of system reliability in the Regional System Performance Model whenever any changes to supply sources and/or changes demand projections.

o Evaluate the improved system reliability with each of the long-term water supply options.

G. Section 7 - Regulatory Review

As a part of planning to meet the water needs of the member governments, it is important for Tampa

Bay Water to consider existing and proposed regulations at the State and Federal levels. Drinking water

standards are established at the Federal and State levels to protect human health. The Florida

Department of Environmental Protection typically adopts drinking water standards as mandated at the

federal level; however, State standards may be more stringent than the Federal standards. The Florida

Department of Environmental Protection is also responsible for permitting water treatment facilities

and distribution systems.

Tampa Bay Water is required to provide water that meets all State and Federal drinking water standards

as well as Exhibit D Standards, which are established in the Master Water Supply Contract to further

refine the definition of a “Quality Water” to be provided to the member governments. Table ES-2

summarizes major water-related regulations under development at the Environmental Protection

Agency.

Long-Term Master Water Plan 2013 Executive Summary

Tampa Bay Water Page ES-15

In operating its facilities and planning for future supply sources, Tampa Bay Water should continue to

participate in Federal and State regulatory policy initiatives in order to understand their effect on

operations and future water supply development options. At the State level, Tampa Bay Water can

provide constructive input on initiatives such as the Florida Department of Environmental Protection’s

Consumptive Use Permitting Consistency effort to help improve the permitting process. At the Federal

level, things such as source water quality based upon established Maximum Contaminant Levels and

Maximum Contaminant Guidance Levels, as well as potential emerging contaminants and Contaminant

Candidate List constituents that might become regulated in the future will need to be followed. The

research being performed on such constituents, their potential effects on public health, the

environment, and related treatment aspects will continue to provide new information and a better

understanding on how they might affect water supply. The research process is expected to occur over a

long time span and thus will allow Tampa Bay Water time to adapt should any new regulatory limits be

set. In the meantime, Tampa Bay Water can continue to participate in the regulatory development

process to ensure that any proposed legislation is supportive of Tampa Bay Water’s goal to provide safe

clean drinking water.

H. Section 8 - Source Water Protection

Protecting the sources of drinking water supply in our region is essential to protecting the public health

and maintaining a sustainable water supply in the future. Protecting the sources of the region’s drinking

water supplies also protects the water supply investment made by the board.

Source water protection is the first step in a multi-barrier approach to drinking water protection. Tampa

Bay Water has a diversified water supply portfolio, consisting of groundwater, surface water and

desalinated water. The Agency relies on 13 consolidated wellfields, 2 isolated wells, the Hillsborough

River, Alafia River, Tampa Bypass Canal, Regional Reservoir and the Seawater Desalination Plant to

meet the daily demand for quality drinking water.

During the 2008 Long-Term Master Water Plan update, the board approved the creation of a source

water protection program. In 2009-2010, the agency undertook this effort and developed an Integrated

Source Water Protection Program which was approved by the board in 2011. This Program contains

several source water protection options. Detailed information regarding each of those options can be

found in Appendix B.

Tampa Bay Water’s Integrated Source Water Protection Program employs a range of initiatives to

prevent and reduce source water pollution, such as education and outreach programs, participation in

regulatory initiatives as well as partnerships and monitoring programs. As a wholesale water provider,

Tampa Bay Water does not have regulatory purview over the land areas that influence the sources of

Long-Term Master Water Plan 2013 Executive Summary

Tampa Bay Water Page ES-16

supply. Collaboration with member governments, regulatory agencies and stakeholders are important

components of a successful source water protection program for Tampa Bay Water.

Tampa Bay Water staff will continue to examine the Agency’s source water protection needs and

recommend to the board an annual budget for source water protection activities. This will help ensure

that the efforts most beneficial to the Agency’s program are funded and implemented each year.

I. Section 9 - Climate Variability and Long-Term Climate Change

Use of surface water supplies imposes a new level of uncertainty in our water supply system and makes

the region more susceptible to extremes of weather and climate. Because Tampa Bay Water has become

more reliant on surface water sources, it is important to examine the relationship between climate

change and water quality and quantity issues.

Important effects of climate change that will potentially affect Tampa Bay Water include:

Impacts of increasing temperature on evapotranspiration and seasonal rainfall patterns;

Increasing rainfall variability and frequency of extreme events (e.g. more hurricanes, more

droughts);

Source water quality changes due to temperature changes or increased runoff; and

Changes in rainfall patterns and temperatures affecting water use patterns and future water needs.

Risk-based decision making is one approach that can be used to balance risks and costs and incorporate

the uncertainties associated with climate change. Risk assessment includes evaluating the likelihood of a

climate change impact occurring. Adaptive management supports action in the face of uncertainty and

limited scientific knowledge. Tampa Bay Water’s current mix of supplies is diverse. This diversity offers

opportunities for adaptive planning and adaptive management which can offset some of the effects

associated with climate uncertainties. Tampa Bay Water’s board has approved the incorporation of

adaptive management into long-range planning activities. The key components of adaptive management

are defined as follows:

Implementation- water supply planning, construction programs and operations feedback

Feedback- monitoring and review of economic and environmental outcomes of management

actions

Re-evaluation- conceive new strategies (planning and operational) as information accumulates and

understanding improves

Long-Term Master Water Plan 2013 Executive Summary

Tampa Bay Water Page ES-17

Repeat Loop- continuous improvement process

Tampa Bay Water is moving forward with its risk assessments to understand the uncertainties associated

with climate change and variability and how this may affect long-term water supply planning activities

and implementation of adaptive management strategies.

J. Section 10 - Demand Management

Through the six member governments, Tampa Bay Water meets the drinking water demands of more

than 2.3 million people. According to member governments’ actual and projected 5-year water

conservation plans, it is estimated that the member governments collectively saved approximately 26

million gallons per day (mgd) of potable water by the end of the water year 2011, and will save up to

approximately 30 million gallons per day (mgd) by the end of water year 2016.

The Demand Management Plan investigates the benefits and costs of water demand management as a

quantifiable, alternative water supply source. The Demand Management Plan is one way to further the

Agency’s strategic goals to achieve reliability of its water supply and delivery system to its member

governments.

Demand Management Plan efforts are intended to serve as a complement to the traditional water supply

planning process in meeting current and future water demands. Demand management encompasses a

set of activities designed to:

Provide a better understanding of how and why water is used

Forecast human demands for water supplies

Develop prospective water-using efficiency (demand reduction) measures

Identify programmatic and project goals, evaluation criteria, performance measures and

monitoring mechanisms

Define and evaluate program effectiveness and goal achievement

Evaluate the benefits and costs of efficiency measures as an alternative or a complement to supply

development

The demand management effort includes an analysis of past and present water savings, as well as an

analysis of avoided supply costs related to improved water use efficiency. The Demand Management

Plan examines things such as distribution of water use, an evaluation of achieved water savings from

existing member governments’ programs, and the analysis of new and upcoming water technologies

designated to lower water use.

Long-Term Master Water Plan 2013 Executive Summary

Tampa Bay Water Page ES-18

In February 2013, the Board adopted a Water Efficiency resolution, which gives Tampa Bay Water a

direction on activities that need to be included in the Demand Management planning efforts. The Water

Use Efficiency resolution incorporates water use efficiency evaluation efforts into the Agency long-term

planning process. The resolution is based on the following findings:

Develop and implement data collection, management and analysis protocols and procedures for

the continued assessment of passive water use efficiency within Tampa Bay Water service area

Integrate passive water-use efficiency into the Agency’s Long-Term Demand Forecast and

Future Needs Analysis

Include the Water Use Efficiency Evaluation as an element of the Long-Term Master Water

Plan

Include an updated evaluation of potential active measures for implementing efficient water-use

products as part of future options for the next Long-Term Master Water Plan update

Incorporation of the effects of increased water-use efficiency into the Agency’s long-term planning

process provides the board with more supply policy options, affords Tampa Bay Water and its member

governments a supply buffer, and allows Tampa Bay Water to prepare and plan for the effects due to

changes in water use efficiency.

K. Section 11 - Potential Future Water Supply Sources

As required by the Interlocal Agreement, Tampa Bay Water must update its Long-Term Master Water

Plan every five years to ensure that the Agency has adequate supply to meet the region’s demand for

quality drinking water. During the 2008 Long-Term Master Water Plan, Tampa Bay Water looked at

approximately 300 potential water supply projects. The board approved seven project concepts for the

Master Water Plan. Current demand projections show that the existing water supply facilities are

sufficient to meet the demand for quality drinking water over the next decade. Due to the slow regional

demand growth, no project has to be chosen from the Master Water Plan list for implementation during

this plan update. The seven project concepts can be carried into the 2013 Long-Term Master Water Plan

and included in a planning-feasibility program over the next five years. The seven project concepts

approved by the board are:

The board’s goals for Master Water Plan projects include: environmental stewardship, cost and

reliability. These are described as follows:

Environmental Stewardship: Tampa Bay Water delivers high quality drinking water in an

environmentally responsible manner. The Partnership Plan and the Interlocal Agreement that drove the

creation of Tampa Bay Water had environmental stewardship as one core motivation. Tampa Bay Water

continues to monitor and optimize its operations to ensure that its water production operations

incorporates the responsibility to develop and implement future sustainable water supplies, minimizing

electrical power consumption, greenhouse gas production, chemical usage, and other factors involving

environmental consequences.

Cost: Balancing fiscal responsibility with reliability and environmental stewardship is also important in

Tampa Bay Water’s water supply approach. Minimizing the cost of all operations, from source to tap,

helps minimize rate impacts, consistent with meeting reliability and environmental stewardship goals.

This focus on efficiency helps fulfill Tampa Bay Water’s mission of public service, ensuring the region’s

water needs are met in the most economical manner.

Reliability: Because Tampa Bay Water is unequivocally committed to meeting the needs of its member

governments continuously, reliability of its supply sources is of primary importance. Water supply

source reliability addresses the challenges Tampa Bay Water faces in accomplishing its mission, including

source water protection, drought resistance, diversification, adequate supply, source optimization,

storage, and transmission flexibility. Furthermore, the potential impacts of future climate effects,

particularly increased climatic variability, can affect source water quantity and quality. System reliability is

also critical to ensure that the public health responsibility of water supply is continuously maintained, as

well as providing the flexibility to maintain environmental stewardship.

Tampa Water Department2015 – 2019 Water Conservation Program

Background and Introduction

To provide a dependable alternative to a scattered system of poor quality wells, the City of Tampa constructed a dedicated water treatment facility adjacent to the Hillsborough River in 1924. The facility, which is a designated American Water Landmark, is currently known as the David L. Tippin Water Treatment Facility. The Water Treatment Facility produces around 90 percent of the 80 million gallons of water per day that is consumed by Tampa Water Department customers.

In 2000, the plant was restored to its original Moorish-Spanish decor, and, while the architecture of Tampa's original water treatment plant has been preserved, the treatment process continues to change and improve as technology advances. The plant houses Florida's only municipally-owned, state-certified, complete drinking water laboratory. Throughout the treatment process, continuous and complete water analyses ensure that Tampa's water quality exceeds all State and Federal standards. The Tampa Water Department is the only Florida-located water utility and one of 13 water providers in the United States that was recognized in 2013 with a 15 Year Directors Award for delivering superior quality drinking water to customers.

In 1989, in response to rapid population growth, record drought conditions and projected future water supply deficits, the Tampa Water Department (TWD) implemented a formal Water Conservation Program that has been consistently recognized around the nation for its leadership, innovation and achieved demand reductions. Since its inception, the program has grown to a multi-faceted effort that includes operational, programmatic and policy measures.

Tampa’s Water Conservation activities are part of a long-range water conservation planning process that incorporates the goals of responsible stewardship of Tampa’s water supply, limited reliance on the regional water resources to augment Tampa’s water needs during dry periods, and the use of appropriate business practices to safeguard the fiscal well-being of the Tampa Water Department while retaining already achieved water use efficiencies and contributing to:

Future economic development and growth while protecting local and regional water resources,

Reduction or deferral of costs associated with of maintaining and expanding water delivery, treatment, and disposal systems, and

Reduction of energy and maintenance costs of TWD facilities.

Potable Water Use

The TWD water supply system provides water to industry, wholesale accounts and residential customers within Tampa’s water service area. Tampa records and analyzes consumption data and reports the data to Tampa Bay Water and to the Southwest Florida Water Management District.

Retail Customer Classifications

Customer classifications differ in their characteristics relevant to water use. Single family (SF) and multi-family (MF) accounts reflect strictly residential water use. Single family homes typically have irrigated, individually landscaped yards, and those in deed-restricted or similar planned communities may also have any of a variety of observed irrigation configurations ranging from individually-metered, self-controlled to individually-metered, association-controlled to association-metered and association-controlled. Deed restricted and similar planned communities within the Tampa service area also include irrigated landscape common areas similar to the common-area landscape found at multiple-family residential units and many business settings in our community, with water sourcing ranging from metered potable to pond and lake water to District permitted wells. Non-residential accounts include government/public water use in parks, prisons, government buildings, and medians; offices, businesses, shops, restaurants and hotels, and industrial use in production and manufacturing processes.

System-Wide Historical Use

Since 1989, when Tampa launched its formal water conservation program, the total population served by the TWD increased virtually every year until 2010, when the number declined. This drop in “functional population served” is believed to be due to economic pressures and revisions in methods of calculation. Revisions to methods of calculation, as required by our permitting agency, the Southwest Florida Water Management District, also resulted in a change in the per capita values. For the reporting year 2013, the TWD reported a compliance per capita of 106 gpcd. A history of average pumpage per capita and adjusted use per capita is shown in Table 1.

Consumptive water use frequently is expressed in gallons per capita per day (GPCD) or the average gallons used per person per day. Per capita values shown in Table 1 are calculated for Tampa’s functional population, which includes not only residential and business customers but commuters, tourists, and other non-residents who use water in Tampa while here temporarily for business or pleasure.

City of Tampa Monthly Demand – Five-Year Perspective

Within the past seven years, as reflected in the Figure 1 below, Tampa’s month-by-month water demand and its cumulative annual water demand continues seasonal fluctuations but remains below 2007 levels. The reduced demands are attributed, in part, to athe City’s active, comprehensive approach to water conservation and efficiency.

City of Tampa Monthly DemandFigure 1. FY 2007 – FY 2014

Note: WY 2007 – WY 2014 designation in legend is the equivalent of FY 2007 – FY 2014. Values for April and May 2009 reflect demand during period when hand-watering only imposed to protect Tampa’s primary source.

Water Conservation Goals and Objectives

The overall goal of Tampa’s water conservation efforts is to ensure a sustainable water supply to meet community demands during normal and emergency conditions. This section provides a brief description of water conservation activities and measures employed by the Tampa Water Department.

Operational Measures

Source and Finished Water, and Service Connection Metering

All raw water flows and finished water flows are metered. All existing service connections are metered and the City requires meters for all new connections. TWD meters all treated water delivered to its wholesale customers. These meters are calibrated annually. The TWD monitors meter activity through its Supervisory Control and Data Acquisition (SCADA) system.

Fixed-Interval Meter Reading

Meters for all Tampa water customers are read monthly. Locations where the recorded meter reading is outside a “normal” range is scheduled for a re-read to verify or correct the read, as is appropriate. A self-help kit is available to locations with verified high reads to assist them in determining and addressing the possible causes of the high usage.

Meter Testing, Calibrating, Repairing and Replacing

The TWD Preventative Maintenance (PM) Team is responsible for performing all functions in respect to the operation and maintenance of Tampa’s water meters. Tampa’s policy is to replace residential meters after they have been in service for 10 years to ensure metering accuracy. To comply with that policy, approximately one-tenth of the residential meters in our system are replaced on an annual basis.

All 2-inch and larger meters in the system are field tested annually, and those that are not metering to within a range of 98 percent to 101 percent accuracy are recalibrated or, if necessary, replaced. The TWD also reviews existing meters at commercial locations as part of a “right-sizing” initiative to ensure that the meters installed at those locations are capable of recording demand at those locations with the highest degree of accuracy possible.

System Audit

To ensure minimal real and apparent system loss, the TWD monthly compiles and reviews data related to water production and metered sales to identify and respond to factors contributing to water loss.

Distribution System Pressure Control

Tampa maintains 35 continuously-monitored pressure stations around the system, connected to SCADA, to maintain the distribution system. There also are several pump stations and elevated tanks in place to assist in meeting peak demands. Each monitored station is equipped with minimum- and maximum-alarmed limits for pressure to ensure that the system is maintained within the parameters established by the Health Department.

Recycled Water for Filter Backwashing at Treatment Plants

The TWD uses dual media filers at its water treatment plant that require routine backwashing. Air scouring is used to help dislodge material collected in the filter media, and backwash is then used to remove dislodged material to a thickener tank for reclamation. After settling in the thickener, the backwash water is recycled to the beginning of the treatment stream for reprocessing. Solids collected in the thickener are removed for dewatering and disposal, and water captured during the dewatering process also returns to the beginning of the treatment train for reuse.

Customer Leak Notification

The TWD completes re-reads for locations where usage exceeded prior history normal ranges for a location and leaves door tags at locations where re-reads confirmed high usage to alert customers of a possible leak on the customer side of the meter. Additionally, the TWD continues to explore the use of automated meter reading technology. It is anticipated that such a conversion would include the ability to establish earlier customer leak notification and high-use notification programs.

Water Conservation Coordinator

TWD maintains a staff of three full-time water conservation coordinator positions to plan, implement and evaluate its water conservation activities. The water conservation team is a part of the department’s Distribution and Consumer Services Division, which includes customer service and billing functions. The Conservation Section's close alignment with the Department's distribution division activities ensure the conservation team’s involvement in customer-focused and internal water demand reduction and loss control programs.

Reuse Expansion

The Tampa Water Department continues to explore opportunities to increase the availability of reclaimed water for irrigation and commercial application and indirect potable use.

Aquifer Storage and Recovery

With ever-increasing water demands and seasonal variations in surface supply, it is challenging at times to provide solely from the river source for Tampa’s water demands. Tampa currently has eight Aquifer Storage and Recovery wells that store up to 1 billion gallons of water when excess surface water supply is available. The Tampa ASR system

is operated seasonally, storing water during rainy periods and recovering when supplies are short.

Educational and Program Measures

Informative Billing and Water Bill Inserts

Each utility bill issued by the City of Tampa provide the customer with usage for the billing period. The usage is expressed in units and in gallons, rounded and expressed in 1,000 gallon increments, to assist the customer in comparing their most recent consumption with the information provided in the 13-month usage history included on the face of the bill. City of Tampa utility bills are mailed monthly to each customer to a mailing address designated by the customer. Additionally, customers may view and download current and past bills online for the 12 months prior to the current billing.

In addition to the information routinely printed on Tampa’s utility bills and the online bill view, the following information is featured on the water department’s Web site:

1. Rate structures for each billing class, 2. An explanation of any water-related surcharges, including information about how

the application of such surcharges is triggered, 3. Conversion information to assist customers in doing their own calculations to

convert metered units to gallons, and 4. Three years of average use for all user classes to assist customers in comparing

their water usage to other similar users in Tampa.

Tampa’s billing process accommodates billing inserts, which are used to advise customers of available water conservation programs and water use restrictions. The TWD also offers customers the opportunity to subscribe to an electronic newsletter that delivers direct-to-their-email water conservation tips and information about available water conservation programs and water use restrictions.

Retrofit Kit Give-Away

Tampa water customers may request free Plumbing Retrofit Kits and Save Water Kits from the TWD. The Plumbing Retrofit Kit contains the following items: low flow showerhead, bathroom aerators, kitchen aerator, teflon tape, toilet leak detection dye tablets, installation instructions, the most recent Water Quality Report, and informational brochures. The Save Water Kits include toilet leak detection dye tablets, the most recent Water Quality Report, and informational materials on checking for leaks and conserving water. An average of 350 – 400 kits are distributed annually to residential customers with an estimated 2,000 – 2,500 kit content items being distributed in bulk to multi-family and business locations.

Rain Sensor Distribution Program

The TWD provides rain sensors to customers on request at no charge to replace a non-working sensor or to complete an initial installation.

Commercial Pre-Rinse Spray-Value Retrofit Program

The TWD offers free low-volume (1.28 gpm) pre-rinse spray valves to Tampa-located restaurans and locations with on-site commercial kitchens.

Industrial, Commercial and Institutional Water-Use Efficiency Evaluation Program

Since approximately 40 percent of Tampa’s account base is non-residential, the TWD annually maintains an Industrial, Commercial, and Institutional Water-Use Efficiency Evaluation Program that offers both on-site assistance and a comprehensive self-guided evaluation template to help non-residential locations identify water efficiency measures and to incorporate them into a site-specific water conservation plan. The on-site portion of this program is structured in such a way that the customer is an active participant throughout the entire process to ensure that the customer gains not only the evaluation and an efficiency plan but also gains the ability to self-conduct on-going evaluations to ensure that gained efficiencies are maintained. This program also includes a series of industry-specific template documents to help industrial, commercial and institutional customers identify industry specific efficiency measures and options.

As a part of its focus on these customer categories, the TWD supports the Southwest Florida Water Management District’s Water C.H.A.M.P. and Water PRO programs.

Water Use Surveys

To assist its customer base, the TWD offers a “customer care” program that provides referred customers with an on-site water use survey to assist with identification of leaks and/or other conditions that may contribute to increased water use and increased water and wastewater utility costs.

Public Information/Education

The TWD purchases and publishes a variety of brochures and other literature promoting water conservation and water use efficiency. Brochures provide information on water conservation issues, such as efficient irrigation, irrigation with reclaimed water, leak detection and repair, and indoor water conservation. The TWD also maintains a 24-hour, 7-day-a-week water conservation hotline that provides customers with current information regarding water use restrictions. In addition to the available brochures, the TWD maintains a Web site presence that features more than 100 pages of water conservation and water efficiency information and access to partner-sponsored water conservation programs and materials and uses social marketing tools, such as Facebook and Twitter to reach the widest possible audience within its service area. The Web-located information is designed to provide customers with on-demand access to every brochure published by the Department in addition to water-conservation programs and tips.

Plumbing Workshops

To assist in addressing concerns associated with residential account customer-side leaks, the TWD is partnering with Erwin Technical Education Center in Tampa to provide tuition-subsidized plumbing and general home maintenance workshops for residential and commercial account holders. This program launched immediately at the start of FY2014.

Customer Surveys

Tampa periodically talks with or contacts prior conservation program participants by mail to collect information that will assist in evaluating programs and activities.

Workshops

The TWD cooperates with a variety of partners to sponsor rain barrel, Florida-Friendly landscaping and other water-conservation workshops around the community.

Wholesale Water Supplier Assistance Program

Tampa cooperates and coordinates with its wholesale customers in developing their Water Use Efficiency Plans and will continue to participate in and support those efforts.

Policy Measures

Conservation Rate Structure

The City of Tampa continues the use of an inclining tier rate structure, which is in place for all customer categories. In 2007, Tampa’s City Council approved a five-year plan for annual rate increases, and, in accordance with that plan implemented increases for all customer classes in 2008, 2009 and 2010. Additionally, in FY 2010, the TWD expanded the tier structure for single-family residential customers from 5 to 7 usage ranges and adopted a sharply increasing rate structure for single family residential customers using the highest volumes of water. Tampa’s FY2011 single family residential rate structure, with the additional of Tiers 5 - 7 was:

Inside City of Tampa Outside City of Tampa

Tier 0 0 – 5 ccf $2.09 $2.61 Tier 1 6 – 13 ccf 2.43 3.03 Tier 2 14 – 26 ccf 4.07 5.08 Tier 3 27 – 46 ccf 5.44 6.80 Tier 4 47 + ccf 6.28 7.85

First tier rates for non-residential customers are equivalent to the Tiers 1 – 4 and the usage in each tier is customer-class specific and based on threshold amounts established for specific types of use. For instance, the threshold rate for a hotel/motel customer is established based on the number of rental rooms the facility has. For a non-residential customer whose usage does not exceed the assigned threshold for that location, each unit of water metered is billed at Tier 1 rates; consumption the exceeds the threshold but does not exceed twice the threshold level is billed at Tier 2 rates; consumption that exceeds twice the threshold but does not exceed 3.5 times the threshold level is billed at Tier 3 rates; and consumption that exceeds 3.5 times the threshold level is billed at Tier 4 rates.

Landscape/Irrigation Ordinance

Chapter 27 of the City of Tampa’s Code of Ordinances requires the use of Florida-Friendly landscape principles for the design of new landscape and includes these measures:

1. An incrementally reduction to the amount of irrigable turf allowed that caps that landscape component at no more than 25 percent of the total irrigated area after 2011 for new landscape installation.

2. Landscaped areas shall consist of at least sixty (60) percent native plant material and/or plant material adapted to local climatic and edaphic conditions.

3. A layer of mulch to a minimum depth of three (3) inches shall be specified on the site plan in plant beds and around individual trees in turf areas.

4. Sprays and rotors are required to have matching application rates within each irrigation zone, and mixed zones are not permitted.

5. All irrigation systems are required to be designed to avoid over spray, runoff, low head drainage, or other similar conditions where water flows onto or over adjacent property, non-irrigated areas, walkways, roadways, structures, or water features. And, emitters and sprinkler heads are encouraged to be located at least two (2) feet from buildings and water should not hit the building while operating. Narrow areas (four (4) feet wide or less) are not to be irrigated unless low-volume irrigation is utilized.

6. Newly installed irrigation control equipment is required to include an automatic irrigation controller having program flexibility, such as repeat cycles and multiple program capabilities, a battery back-up or nonvolatile memory to retain the irrigation program(s), and an operable rain sensor or other device, such as soil moisture sensor, to prevent unnecessary irrigation.

Stringent Restriction Enforcement and Reduced Irrigation Hours

The City of Tampa stringently enforces all local and regional water use restrictions. In May 2006, the TWD moved to a citation on first observance of a violation policy in lieu of the issuance of warnings in an effort to increase restriction compliance and reinforce the message to Tampa water users that conservation is a year-round activity. Additionally,

within its local water use restriction ordinance, Tampa reduces the permitted hours allowed by the Southwest Florida Water Management District (before 10 a.m. and after 4 p.m.) by two hours per day on scheduled irrigation days. Tampa does not permit irrigation between 8 a.m. and 6 p.m.

Low-Volume Fixture Ordinance

In concert with the effective date of the U.S. Energy Policy Act of 1994 (EPACT), the City of Tampa established water conservation standards for plumbing fixtures installed in new construction, and initiated a first-of-its-kind toilet rebate program that has served as a model for subsequent programs for utilities, water authorities and water management agencies across the nation. The TWD routinely distributes replacement showerheads and faucet aerators with water use efficiencies exceeding the requirements of EPACT. The TWD also is enrolled as a WaterSense partner, promoting the installation and use of efficiency-tested and rated water appliances and fixtures.

Rain Sensor Ordinance

The City of Tampa’s water use restriction ordinance includes language that requires the use of an automatic rain sensor or other rain sensing technology for all automatic irrigation system.

Reclaimed Water Mandatory Hook-Up for Irrigation

All newly installed irrigation systems in Tampa must connect to reclaimed water when they are in a location where reclaimed service is available.

Conclusion Tampa is fully committed to maintaining a comprehensive water conservation program that addresses our community’s on-going need to ensure a safe, reliable water supply that meets demands during normal and emergency conditions. This commitment is realized through operational, programmatic and policy-related activities, and is fully integrated throughout the Water Department’s business activities.

As a result of Tampa’s long-term approach to water conservation and through engagement of Tampa’s water users, since the inception of the program in 1989 total system demand and gpcd has declined significantly. The City remains committed to water conservation and the Tampa Water Department will build on its past conservation successes and continue to update and revise its programs in order to remain at the forefront in the implementation of water conservation programs.

Demand Projection Formulas The following is a summary of the data collected and formulas used to calculate the various demand

projections considered for the Tampa Potable Water Master Plan. Ultimately the demand projection

used for the system analysis was an average of the four sources available; Southwest Florida Water

Management District (SWFWMD) 2015 projections, Tampa Bay Water (TBW) 2015 projections,

Exhibit K low and high projections prepared for TBW.

Existing water consumption and unmetered water losses will be allocated to the hydraulic model

based on customer billing data, GIS, and pipe break data. For each customer account the average

annual consumption was allocated to model junction nodes based on billing data for 1-year of

record. Each customer meter is geospatially located and linked to the specific account demand via

the account number. The geospatially accurate consumption information will then be loaded to the

model by assigning the consumption to the closest model pipe and weighted by distance to the

closest junction. The unmetered demand portion will be calculated based on the comparison

between the WTP and imported water records and the customer billing consumption, and then

allocated based on pipe break data.

Projected future demands will be adjusted to match the total system demand discussed above and

will be based on the property parcel shapefile as prepared by the SWFWMD.

SOUTHWEST FLORIDA WATER MANAGEMENT DISTRICT PROJECTIONS

Population Estimates/Projections

Population projections are based on the University Of Florida Bureau Of Economic and Business

Research (BEBR) provided projections from 2014. The populations are distributed spatially based

on property parcels and summarized in a shapefile. Since there are so many commuters and tourist

related demands in the State, SWFWMD uses a functional population to estimate the needs for

future infrastructure growth and is defined per the formula below.

Functional Population = Permanent/Seasonal + Tourist + Net Commuter

Demand Projections

SWFWMD tracks per capita demand yearly based on the Water Use Permit reports. The following

formulas define the water use for utilities.

Withdrawals (WD) + Imported Water (IM) = Gross Water Use + Exported Water (EX) + Treatment Losses (TL)

Where, Treatment Losses (TL) = Losses at WTP, ASR Discharges and WQ Flushing Losses

For the purposes of this comparison,

Distribution System Requirements (Total Water Use) = Gross Water Use + Exported Water (EX) + WQ Flushing

Where,

Gross Water Use = Functional Population x Per Capita Demand OR

Gross Water Use = Withdrawals (WD) + Imported Water (IM) - Exported Water (EX) - Treatment Losses (TL)

Per Capita Demand (actual yearly) = Function Population Estimate / Gross Water Use

Future projections are calculated using an average per capita demand and the projected functional

population projections.

Per Capita Demand (future) = 5 year average (2008 – 2012) = 113 gpcd

Exported Water (future) = 7 year maximum (2008 – 2014) = 3.4 MGD

WQ Flushing (future) = 5 year average (2010 – 2014) = 0.7 MGD

Total Water Use Projected = (Functional Population Projection x Ave. Per Capita Demand) + Exported Demand + Ave.

EXHIBIT K - PREPARED FOR TAMPA BAY WATER The Exhibit K document prepared by the Tampa Water Department (TWD) provides a range of

potential future supply needed by the City from TBW. The TWD calculates the future high and low

system demand based on a number of factors and then subtracts the supply provided directly by

the City through the D.L. Tippin WTP to calculate the supply needed from TBW. The information

below documents the process to calculate the total system demand.

Population Estimates/Projections

Two population projections are calculated for Exhibit K; the low is based on the growth rates

provided by SWFWMD from the 2013 projections and the high is based on the growth rates

provided by the Florida Demographic Estimations. Table 2 below summarizes the population

projections used for the low demand projections. The growth rates were calculated from the data

provided by SWFWMD and applied to the real population estimate of 2012 to recalculate the

population projections. The 2030 growth rate was applied to the 2035 projection since that data

was not available.

Demand Projections

Exhibit K uses the following formula to calculate the projected total system demands.

Total Water Use Projected = Residential (R+A) + Commercial/Industrial (C+I) + Distribution Water Loss – Reuse

Offset

Where,

Residential (R+A) = Service Area Population x Per Capita Demand; Per Capita Demand = 25 yr. average (76.7 gpcd)

Commercial/Industrial (C+I) = 5 yr. average 2009-2013 (22.5 MGD in 2013)

Water Loss = 5 yr. average 2009-2013 (7.5 % in 2013)

Reuse Offset = 3 yr. average 2011-2013 (2.7 MGD in 2013)

For the Low Demand projections the following were assumed increases in demand:

Residential (R+A) = Constant @ 76.7 gpcd

Commercial/Industrial (C+I) = 0.5% increase per year starting at 22.5 MGD in 2013

Population & Demand Projections | City of Tampa

8 APRIL 2016

Water Loss = Constant @ 7.5 %

Reuse Offset = 1.0% increase per year starting at 2.7 MGD in 2013

For the High Demand projections the following were assumed increases in demand:

Residential (R+A) = Constant @ 76.7 gpcd

Commercial/Industrial (C+I) = 1.0% increase per year starting at 22.5 MGD in 2013

Water Loss = Constant @ 7.5 %

Reuse Offset = No Reuse Offset was accounted for

TAMPA BAY WATER 2014 DEMANDS TBW prepares an annual Demand Forecast Evaluation and Update to project the amount of water

supply needed within their service area. The annual updates are based on the long-term demand

forecasting models using three sector-specific econometric models. Each model generates demand

forecasts based on weather and socioeconomic projections. The demand forecast for the City of

Tampa with a 2014 base year is summarized the Table 5 below.
