THE RESOURCE DEVELOPMENT PLAN:
REGIONAL WATER SUPPLY
SUMMARY REPORT


INTRODUCTION AND OVERVIEW


The West Coast Regional Water Supply Authority
(Authority) was established by the cities of
Tampa and St. Petersburg and the counties of
Hillsborough, Pasco, and Pinellas in 1974 as a
result of state enabling legislation. The city of
New Port Richey was added in 1982 as a non-
voting member. The Authority was created to
develop, store and supply water for county or
municipal purposes, as outlined in its mission
statement:

To provide its members with adequate and
reliable supplies of high quality water to
meet present and future needs in an
environmentally and economically sound
manner.

Balancing the need for water and its availability is
a challenge for growing communities. The
Hillsborough-Pinellas-Pasco (Tri-County) area
has experienced rapid growth and economic
development during the past three decades that
have resulted in an increasing need for water
supplies. Comparisons of supply and demand
show that although the regional water supply
system presently operates with sufficient capacity
to meet customer demand, reserve margins are
already inadequate and likely to become more so
without the development of new water sources.

Over the past 20 years the Authority and its
member governments have worked in a
cooperative alliance to meet the on-going needs
of the Tri-County area and its current service
population of approximately 1.8 million. In 1978,
the Authority published the first comprehensive
regional water supply plan (Regional Water
Supply Needs and Sources). The plan was
updated in 1982 and again in 1986. Due to
continued growth, and increased community
interest, a new approach to planning for water


AN INTEGRATED
PLAN


supply in the Tri-County area was needed.
Accordingly, the Resource Development Plan
(RDP) was begun in 1993.

The RDP was based on a comprehensive analysis
of current and future demand, supply sources and
facility capacities, and provided specific
recommendations for developing new water
supplies as an integrated water resource plan.
Implementation of the plan will enable the
Authority to continue to meet its obligations to
develop, operate, and maintain the regional
public water supply system while minimizing
adverse impacts.

Planning Process

The RDP was an integrated resource planning
process (depicted in Figure 1), managed by
Authority staff and consultants. The planning
team relied heavily on input and advice from the
following:

* A Resource Advisory Committee (RAC)
specially formed to assist with the RDP,
consisting of representatives of the
Authority's member governments,
Southwest Florida Water Management
District (SWFWMD), U.S. Geological
Survey, Florida Department of
Environmental Protection, University of
South Florida, Saint Leo College,
Hillsborough County Environmental
Protection Commission, and Hillsborough
County City-County Planning Commission;


* The Authority's
Committee (TAC),
directors from the
governments.


Technical Advisory

Indirect guidance was also provided by the

Resource Development Plan November 26. 1996


(TBWCC), which held a series of meetings at
about the same time the Resource Development
Plan was being finalized. An ad-hoc body co-
chaired by Board members from the Authority
and the Southwest Florida Water Management
District, the TBWCC was created to help build a
consensus on the state of Tampa Bay's water
resources and the best means of meeting future
needs while protecting the area's natural
resources.


Adopting a Recommended Plan


The final step of the planning process was the
drafting and adoption of a recommended plan.
The Authority Board of Directors conducted
public workshops to discuss the future supply
needs and the range of alternatives that could be
considered. In these sessions the Board
established five objectives for the recommended
plan:


Determining Water Supply Needs


To begin the planning process, the Authority and
its consultants held a series of work sessions with
member utilities to establish population and water
demands of the Tri-County area and make
projections for the future. An inventory of the
existing facilities was then conducted to determine
the available capacity. In addition, resource
management measures, means of optimizing
existing facilities, and ways to reduce current and
future demands were researched.

Determining Potential New Sources of Supply

After projected demands and facility capacities
were compared, the need for new sources was
assessed. The RAC held a series of work
sessions to determine potential future sources of
supply. From these sources, an initial series of
alternative supply plans was developed.

Building Alternative Supply Plans

The RAC and TAC then established 10 criteria to
evaluate and rank each potential source of supply.
The supply elements were combined to create
alternative plans to meet the identified facilities
need. Four alternative plans were formed. Each
of the alternatives included three phases of
development:

* Phase 1: 1995-2000 Capital Improvements Plan
* Phase 2: 2000-2015 Master Plan
* Phase 3: 2015-2030 Long Range Plan


* Aggressive conservation
rotational capacity


and reserve/


* Diversified supply sources
* Limited additional groundwater beyond built
and exchanged capacity
Increased drought-proof and drought-resistant
components
Least cost consistent with previous objectives

Based on the five objectives, the Board selected
one of the four alternative plans. The selected
plan was subsequently modified based on
comments received from TAC and SWFWMD.
The recommended plan was presented to each
member government during public workshops to
obtain input from the community. The Authority
also held a public meeting for the Tri-County
area at Gaither High School to provide another
opportunity for the public to comment on the
recommended plan. Following this series of
meetings and workshops, the Master Water Plan
was approved in December 1995, incorporating
the mid-range elements of the recommended plan
plus pipeline interconnections to improve water
transfer capabilities within the system. In
response to input from SWFWMD and the
public, the Authority's Board accelerated the
Master Water Plan, so facilities to meet the area's
water needs for the next 20 years will be
implemented in 10 years, and seawater
desalination will be immediately investigated.

THE RDP: AN INTEGRATED AND


THE RDP: AN INTEGRATED AND
INCLUSIVE PLANNING PROCESS

Population Projections

The Resource Development Plan was based on
water demand projections formulated from
population projections. Population projections
from the present through the year 2030 for each of
eight Water Demand Planning Areas were
developed. These planning areas included:
* Northwest Hillsborough
* South-Central Hillsborough
* Tampa
* West Pasco
* East-Central Pasco
* New Port Richey
* Pinellas
* St. Petersburg

Population projections for water supply planning
(functional service population) take into account
seasonal population and other factors in addition to
permanent residents. Figure 2 presents the
functional service population for the region, as
outlined in the RDP, which projected an increase
of about 800,000 between 1995 and 2030, or
approximately 20,000 people per year.


Water Demand Projections
To determine future water needs, the Authority
analyzed regional water use from 1980 to 1994.
As Figure 3 shows, water use declined after 1989
due to water conservation in the region. Future
use, based on the 1989 per capital rate, was
projected to show what water use might be without
continued conservation. The next demand
projection was based on the 1994 per capital use
(the most current full year of data at that time). In
addition, a demand projection was made
considering further reductions that would result
from the implementation of additional conservation
measures. (Ref. 11)

Reserve Requirements
To meet capacity needs, sufficient water supply
sources must be in place not only to provide for
projected demand but reserve requirements as
well. Reserve requirements, sometimes referred to
as "rotational capacity," include flexibility to
respond to climate conditions, system failures or
limitations, regulatory constraints, or
environmental conditions. This reserve is
essentially water for the environment because it
allows production to be shifted among different
sources in response to environmental stress.
Interconnectivity of the region's facilities is the
foundation upon which rotational capacity is built,

and its implementation reduces the amount of
reserve required as well as improving the overall
efficiency of the system. To ensure adequate
reserves, extra capacity beyond customer demand
must be permitted for the water supply system.

Managing Demand
As the overall understanding and importance of
water resources of the area increases, there is a
corresponding increased need for optimal and
efficient use of the resources. To use water once
and discard it becomes increasingly inefficient.
Thus, the RDP addressed not only development
of new sources, but also efficient use and reuse of
water.

Over the past several years, the Authority and its
members have embarked on major water
conservation programs such as reclaimed water
systems for irrigation, water rate structures that
encourage conservation, and restrictions on
outdoor water use. These and other efforts to
manage demand generated a 14 percent reduction
in per capital use between 1989 and 1994. This
represents a 45 million gallon per day (mgd)
reduction in total 1994 use over what would have
occurred without conservation.


The trend of declining water demands continued in
1995. The 1995 demand was about 219 mgd,
approximately 1.5 percent less than 1994.

As a part of the RDP, additional conservation
measures that appeared to be viable were
identified. The measures are:
* Requiring plumbing fixtures to meet U.S.
Energy Policy Act efficiency standards
* Toilet rebate/replacement
* Plumbing fixture retrofit
* Clotheswasher rebate/replacement
* Dishwasher rebate/replacement
* Irrigation and landscape evaluation
* Irrigation/landscape rebate
* Cisterns/rain water harvesting rebate
* Industrial/commercial/institutional audits
* Reuse of reclaimed water for irrigation and
industrial purposes
* Educational programs

If the Tri-County area continues its low water use
and is aggressive in implementing new or
expanded conservation programs, it is estimated
that an additional 11 percent reduction in demand
could be realized.

Need For New Sources

The total water needs for a fully interconnected
system, based on projected demand including
conservation and rotational capacity, are presented
in Figure 4. Existing supplies are not adequate for
three reasons:

* The graph shows average use, but the system
must accommodate normal variations above
the long-term average that occur from year to
year. This variation above the average is about
5 percent.
* The system is not fully interconnected.
Available water supplies in certain areas
cannot be accessed to meet the needs of other
areas.
There is not sufficient reserve capacity to
rotate production among various facilities in
response to supply system needs, such as
maintenance or failure, or in response to
environmental needs, such as lack of rainfall
in a particular area or observed environmental
stress.


Historically, the Authority's interconnected
regional system and member facilities have
operated below their permitted capacity. For
example, average day actual usage in 1992 was
229.7 mgd, which was more than 20 percent below
the average day permitted capacity of 289 mgd.
At any given time, operational limitations may
prevent existing facilities from being utilized at
full permitted capacity. These limitations may
include: 1) physical limitations such as inadequate
pump or pipeline capacity; 2) equipment downtime
for repair or maintenance; 3) reduced production
for environmental reasons, such as observed
wetland or lake impacts, rainfall, water levels or
trends, and water quality considerations; and 4)
reduced production imposed by regulations.

Rotational capacity is designed to provide
adequate reserves in the system to accommodate
operational limitations and ensure the natural
capacity of a supply source by enabling facilities
to be rested. Reserve needs under current
circumstances have been estimated to be about 25
percent of total customer demand.

Based on the member governments' best estimates
of future demands, including reserves for the
environment, future water needs were estimated by
planning period:


Phase 1: 1995-2000
Phase 2: 2000-2015
Phase 3: 2015-2030


33 mgd
46 mgd
43 mgd


With an aggressive, coordinated conservation
program, it was estimated these needs could be
reduced to the following:


Phase 1: 1995-2000
Phase 2: 2000-2015
Phase 3: 2015-2030


27 mgd
37 mgd
33 mgd


Potential Future Sources Of Water

Following the determination of future water needs,
the Authority conducted a brainstorm session with
the RAC to consider future sources of supply for
the region. These potential sources, many of
which had been proposed in the past in SWFWMD
and Authority documents, ranged from traditional
water sources to technically and politically more
challenging alternatives and resulted in a listing of
83 different sources. The project team then met to
review the brainstorm suggestions and to organize
them into the following categories:

* Optimization of Existing Facilities
* Groundwater
* Surface Water
* Springs
* Reuse
* Desalination
* Inter-Regional Supply

Each different source was reviewed for its
significance as a regional water supply. Also, the
current level of technology was reviewed to
determine if the source could be reliably and
economically developed.


Development And Evaluation Of
Alternatives

The next step in the planning process was the
analysis of supply sources (or plan elements) and
their potential yield and cost. The project team
including the TAC then developed a series of
alternative plans based on combinations of supply
elements.

Element capital costs included preliminary
estimates of construction, engineering,
administration, and contingencies. The estimated
operation and maintenance costs for the elements
covered normal operation of the facilities and
included labor, supplies, energy, maintenance and
parts replacement. In addition, operating costs for
specialized items such as private well replacement,
environmental mitigation, and monitoring and
evaluation were also estimated. Table 1 presents
the water quantity associated with each element
along with a range of total unit costs (capital and
operating and maintenance) per 1,000 gallons.

An evaluation matrix was developed to rate each
supply element on 10 qualitative criteria to create a
ranking. The qualitative criteria used to evaluate
the elements included:

Source of Supply considered the location and
condition of each element, including its long term
viability and whether its quantity is sufficient to
warrant consideration.

Permitability considered the likelihood of
obtaining a permit to use the element.

Health and Safety determined whether there are
any potential public health and safety hazards
associated with utilization of the source.

Economics considered the impact of the water
production from a supply element on the budgets
and water rates of the Authority and its member
governments.

Environmental considered potential
environmental impacts of each element's potable
water production, operation and maintenance
practices and, in the case of desalination,
concentrate disposal.

Energy addressed the energy requirements of
particular water supply elements.

Water Quality considered the quality of the
potential water supply.

Reliability addressed the reliability of the supply
both in terms of quality and quantity.

Location considered the proximity of the element
to the Authority's service area.

Compatibility considered the compatibility of
different supply sources and treatments from a
water quality perspective.

A final ranking of supply elements was developed
which incorporated both cost and qualitative
evaluation factors. Absent any other policy
direction, these factors tended to favor
groundwater elements as cost effective with
acceptable and manageable non-cost impacts.
However, with guidance from the Authority and
its members, a series of alternative plans was
formulated which took into account the evaluation
factors as well as other policy objectives. Each
alternative represented a different approach to
meeting the facilities need of the Tri-County area.
The four alternatives ranged in capacity from 98 to
124 mgd for a fully interconnected system.

Two alternative plans (1 and 2) were based on the
supply element cost ranking and qualitative matrix
evaluations. Alternative 1 followed the cost and
non-cost rankings without consideration of any
other policy objectives. Alternative 2 relied on the
cost and qualitative rankings but incorporated a
preference for new supply sources outside Pasco
County.

Alternative 3 assumed an aggressive conservation
program to reduce the overall facilities need.
Element selection was then based on maximizing
non-groundwater elements while. trying to use
elements ranked in the upper half of the
cumulative (cost and qualitative) ranking matrix.

The selection of elements making up Alternative 4
was based on the following five objectives
established by the Authority Board of Directors:

S Aggressive conservation and reserve/
rotational capacity


* Diversified supply sources
* Limited additional groundwater beyond built
and exchanged capacity
* Increased drought-proof and drought resistant
components
* Least cost consistent with previous objectives

After a series of work sessions and public
meetings on the alternative plans, the Board
accepted Alternative 4 as a preliminary plan for
public review, discussion and possible revision.
The final recommended plan, Alternative Plan 4A,
was developed in response to comments from the
public, TAC, SWFWMD, and the Authority's
member governments.


Alternative 4A

After public meetings before the elected officials
of the member governments and receipt of written
comments from SWFWMD, Alternative 4A
became the recommended plan. It includes
aggressive demand management and a diverse mix
of sources including reuse, surface water, aquifer
storage & recovery, brackish water and seawater.
It also limits new groundwater to a modest
expansion of an existing wellfield permit in Pasco
County and the development/redevelopment of
groundwater resources in eastern Hillsborough
County. The inclusion of more drought-proof and
drought-resistant components was effectively
accomplished with aquifer storage & recovery,
reuse, and a commitment to a developmental
phase which focuses on desalination. Phases 1
through 3 were reconfigured to make more water
available earlier. Specific supply elements were
selected based on least cost consistent with the
other objectives.

The combination of supply elements making up
Alternative 4A is presented in Table 2.

THE ADOPTED PLAN


The Master Water Plan

Although Recommended Plan 4A met the Board's
five objectives, the Board requested the following
modifications based on additional community
input:

* accelerate implementation
* increase emphasis of developmental
alternatives

Accelerated implementation was emphasized
because the existing system lacks sufficient reserve
capacity to meet regional public supply and
environmental needs. The consensus of the
comments during the later public meetings and
workshops was that the adopted plan should
represent a shortening or compression of the
schedule of Recommended Plan 4A.


These refinements to Recommended Plan 4A
resulted in the Master Water Plan. The Master
Water Plan is comprised of the first two phases of
Alternative Plan 4A compressed to a 10-year
implementation schedule instead of the original 20
years. With new sources of supply and an
expanded interconnected system, the ability to
rotate production among a variety of facilities will
enable the Authority to provide improved
environmental stewardship while meeting the
needs of its members.

The Authority Board adopted the Master Water
Plan, as indicated in Figure 5 and Table 3, in
December 1995. The six supply elements of the
Master Water Plan are outlined below:

Cypress Bridge Permit Increase
This element optimizes the use of existing
constructed capacity by increasing production
approximately 4 mgd. (Ref. 1, 3, 5, 9, and 12)

Tampa Bypass Canal Linear Wellfield
Studies conducted on behalf of WCRWSA
and the City of Tampa indicate that additional
supply is available under most circumstances
from the Tampa Bypass Canal. This element
consists of the development of a linear
wellfield along the Tampa Bypass Canal with
a capacity of 10 MGD. (Ref. 4, 8, 9, and 12)

Industrial/Agricultural Exchange
One part of this element will provide
reclaimed water from Hillsborough County to
industrial users in exchange for a portion of
their permitted use of springs in South-Central
Hillsborough County. The other part provides
surface water to agricultural users in exchange


for a portion of their permitted groundwater
use. As a result, total groundwater
withdrawals will be reduced. Excess surface
water from the Alafia River will be captured
and stored in a reservoir in mined phosphate
areas. As the reservoir lake is constructed, the
surrounding environment will be restored and
enhanced for wildlife. Aquifer storage and
recovery (ASR) is also under consideration for
seasonal storage of excess surface water. (Ref.

Resource Development l'lun November 26. 1996


Brandon Urban Wellfield
This project includes the redevelopment of
previously used urban withdrawals through
dispersed wells in Brandon. Existng wells and
sites will be utilized where feasible and the
specific location of new wells and the
wellfield pipeline will be negotiated with
interested parties. (Ref. 3, 9, and 12)

Cone Ranch and Dispersed Wells
This element consists of the development and
management of water resources in Northeast
Hillsborough County. The project includes
supply from Cone Ranch, purchased by the
Authority and Hillsborough County for water
supply, and selected dispersed wells along a
pipeline connecting Cone Ranch and the
Brandon Urban Wellfield. The specific
location of the wells and the wellfield pipeline
will be negotiated with interested parties. The
element includes implementation of a
dechannelization/rehydration project at Cone
Ranch. (Ref. 1, 3, 5, 9, and 12)

Hillsborough Bay Resource Exchange
This element consists of the reuse of water
from the City of Tampa's Howard F. Curren
Advanced Wastewater Treatment Facility. A
portion of water presently discharged to
Hillsborough Bay would be diverted into a
supplemental treatment facility. The "super
treated" repurified water would then be
pumped to the Tampa Bypass Canal.
Concurrently, groundwater will be withdrawn
through a linear wellfield located along the
Bypass Canal and treated at a new or existing
membrane/filter plant. This project includes
the Tampa Water Resource Recovery Project,
cofunded by City of Tampa, the Authority,
SWFWMD, and USEPA. (Ref. 3, 4, 5, 8, 9,
and 12)

These new supplies will be developed in Phases 1
and 2 of the Master Water Plan. Phase 0 includes
three pipeline projects that are underway to
connect existing facilities. Phase 0 will add 20
mgd to the available capacity of the regional
system.

The Master Water Plan also includes
developmental alternatives dedicated to exploring
promising water supply options that may require


sophisticated technologies or unconventional
approaches to regional supply. As technology
advances and understanding increases, the cost of
an alternative may come down. Reductions in cost
will allow earlier implementation of a
developmental alternative. The developmental
alternatives included for evaluation are:

* Brackish Water Desalination
* Hillsborough River High Water
* Seawater Desalination

A Solutionfor Tampa Bay's Future

The Master Water Plan, as adopted by the
Authority's Board, is a solution to the area's water
supply needs. It is responsive to the concerns of
citizens and SWFWMD, and it meets the Board's
five objectives. Aggressive conservation and
reserve/rotational capacity is accomplished
through the goal of further reductions in per capital
demand. A comprehensive demand management
plan is currently being developed with the
Authority's members. The plan will identify the
most cost-effective water saving measures and
quantify the water savings potential in the region.
Initial data collection and analysis and the
generation of demand management options with
member governments is under way. The first of its
kind in Florida, this plan will provide the
foundation for future demand management
programs.

With the accelerated implementation of supply and
transmission elements in the Master Water Plan,
the second part of the first objective is met. The
reserve/rotational goal of 25 percent will be
enhanced over the next 10 years by the early
implementation of projects as specified in the
Master Water Plan.

The second objective of the Board is diversified
supply sources. The supply elements of the
Master Water Plan represent a balance of
traditional and alternative sources. The traditional
sources in the Plan are primarily projects which
have been planned with commitments made for a
number of years, such as Cone Ranch and
redevelopment of the Brandon Urban Wellfield.
The Master Water Plan also represents a broad
blend of alternative sources including surface

water, reclaimed water, repurified water,
desalination and ASR.

The objective of limited additional groundwater
beyond built and exchanged capacity is
accomplished in great part through diversification.
The groundwater supplies outlined in the Master
Water Plan are either limited expansions of
existing facilities, redevelopment of existing or
prior uses, or the exchange of surface and
reclaimed water for existing groundwater use.

Increased drought-proof and drought resistant
components, another Board objective, are
provided in the Master Water Plan first through the
integration of existing sources of supply via new
pipeline projects. The Industrial/Agricultural
Exchange and the Hillsborough Bay Resource
Exchange, which total almost 50 percent of the
new capacity in the Master Water Plan, use the
exchange of reclaimed water as a drought-proof
source. And ASR provides great promise as a way
to efficiently convert seasonally high surface water
flows to sustainable long-term public supply.

As with any plan, the Master Water Plan must
meet our needs at the least cost consistent with
previous objectives. Meeting the current and
future water needs of the region will not be
inexpensive. However, within the bounds of the
Board's first four objectives, the sources of supply
comprising the Master Water Plan were selected
based on least cost as compared to other potential
sources.

In conclusion, the Master Water Plan provides a
balanced, sustainable, long-term approach to the
region's water supply through optimizing existing
facilities, expanding and integrating the regional
system, and adding alternative water supplies to
ensure the best and most efficient use of Tampa
Bay's resources. The Master Water Plan meets the
present and future water needs of Tampa Bay's
residents and provides environmental reserves
dedicated to effective resource management.
