EXECUTIVE SUMMARY
Introduction

The Governing Board of the Southwest Florida Water Management District adopted the "New Water
Sources Initiative" as part of its Fiscal Year 1994 Budget. The purpose of this dedicated fund is to
enhance financial assistance opportunities for "alternative" water source projects such as
conservation, reclaimed water and stormwater reuse, surface water, and desalination. The
Governing Board has allocated $10 million per year as a funding source for eligible New Water
Sources Initiative (NWSI) projects. Basin Boards receiving benefits from the projects selected have
matched the $10 million per year beginning in their Fiscal Year 1995 Budget. NWSI projects
generally receive 25 percent of their funding from the Governing Board, 25 percent from the
appropriate Basin Board(s), and the remaining 50 percent from the local cooperator(s).

Project proposals are submitted to the District each year for NWSI funding consideration. To be
eligible for NWSI funding, a project must have regional water resource benefits. In 1994, 46
projects with costs totaling $250 million were submitted. Twelve "cornerstone" projects were
selected based on recommendations by District staff, Advisory Committees (Public Supply,
Industrial, Agricultural, and Green Industry), and geographically-based "action groups" made up
of members from all water use sectors. Four additional projects were selected for NWSI funding
in 1995. When fully implemented, the 16 projects may provide up to 150 million gallons per day
of water to meet current and future water needs. The 16 projects will also reduce ground-water
withdrawals, rehydrate stressed lakes and wetlands, increase ground-water recharge, enhance
wildlife habitat, and improve flood control.

The 1995 New Water Sources Initiative Annual Report was developed to provide a framework for
future NWSI project selection. The report summarizes the availability of alternative water sources,
reviews issues regarding project development, and provides recommendations for future NWSI
projects. The report also summarizes the scope and status of currently funded projects.

Available Alternative Water Sources

Available quantities of alternative water sources have been estimated for conservation, reclaimed
water, surface water, and seawater desalination (Table 1). The potential for brackish-water
desalination and stormwater reuse were not evaluated due to limited data. It is estimated that more
than 200 million gallons per day (mgd) of alternative water sources, conservation not included, are
available District-wide. The majority of the available alternative water sources are located in the
west-central and southern areas of the District.

The alternative source offering the largest potential is seawater desalination. In the west-central
portion of the District, an almost unlimited amount of water could be developed. Two issues
confronting seawater desalination have been the high costs of water production and concerns
regarding disposal of the brine waste product. Research has demonstrated that through dilution, it
is possible to safely return concentrated brine to the Gulf of Mexico. While cost estimates for
seawater desalination are about $4.00 per thousand gallons, costs will be lower for large-scale
facilities or if desalinated seawater is blended with traditional ground and surface water sources.

Conservation projects usually do not meet the NWSI criteria of providing regional water resource
benefits and, instead, are funded at the local level under the Cooperative Funding Program.
However, since conservation is often considered to be an alternative water source, the potential
water savings from conservation programs have been estimated for this report. Conservation offers
the potential to reduce withdrawals by as much as 170 mgd, depending on the types of programs
implemented and the commitment by the local cooperators. In urbanized areas, conservation can
be achieved through programs such as public education, plumbing retrofit, and low volume toilet
rebates. In agricultural areas, up to 31 mgd of water savings can be achieved through programs
designed to improve irrigation efficiency. Although few conservation programs have been proposed
at the regional scale, the potential exists for conservation programs to result in large water savings.

Note: water conservation projects are generally meugible ior IN wI munomg since mese
projects provide local rather than regional water resource benefits.
The northern area includes Citrus, Hernando, Lake, Levy, Marion, and Sumter counties.

3 The east-central area includes Polk, Highlands, and Hardee counties.
4 The southern area includes Manatee, Sarasota, Charlotte, and De Soto counties.
5 The safe yield of the Hillsborough River is under evaluation.


Status of Currently Funded NWSI Projects as of December 1995

Fifteen out of the sixteen NWSI projects are currently being implemented. (The sixteenth project,
the Lake Jackson/Josephine Watershed project, was canceled.) Feasibility studies for several of
these projects will determine the potential for the future development of certain alternative water
sources. For example, the Manatee Reclaimed Aquifer Storage and Recovery Project will evaluate
the use of aquifer storage and recovery for reclaimed water. The Section 21 and Pasco Rainbow

projects will evaluate the potential for using reclaimed water for wetland and wellfield
augmentation/rehydration. The status of currently funded NWSI projects is summarized in Table 2.

Recommendations for Future NWSI Projects

Recommendations regarding future NWSI projects are presented below. Recommendations are
based on the potential availability of alternative water sources, issues regarding project development,
and the status of currently funded projects.

The quantities of water associated with the NWSI projects currently identified for funding by the
District represent a significant percentage of the available alternative sources of reclaimed water and
surface water in the targeted areas of Northern Tampa Bay Water Use Caution Area (NTBWUCA)
and the Southern Water Use Caution Area (SWUCA). These projects, along with previous and
ongoing Cooperative Funding projects, have accounted for the majority of the available reclaimed
and surface water resources in these areas. The following is a brief discussion of potential future
alternative water source projects that can meet the criteria under the NWSI program:

Seawater Desalination
Seawater desalination appears to offer the largest potential as an alternative water source. The
District should continue to promote and support through funding the promotion and ultimate
development of seawater desalination facilities.

Surface Water
Surface water sources, while limited, are still available in the Southern Water Use Caution Area.
Shell Creek and both the Myakka and Alafia Rivers have potential to be developed as alternative
water sources to offset existing ground-water withdrawals. For each of these systems, off-stream
storage options in the form of aquifer storage and recovery (ASR) or mine pits should be evaluated.
These sources may provide a low cost alternative water source for agriculture since they can be
supplied with minimal treatment (removal of solids) or be blended with reclaimed water to extend
the reuse service capacity.

Reclaimed Water
The potential exists to develop additional reclaimed water sources for several large utilities. An
example of one such utility is the City of Clearwater which had approximately 15 mgd of available
reclaimed water in 1994. Additional studies are needed to determine feasible alternatives for storage
or use of reclaimed water under wet weather conditions. Additional wet-weather alternatives would
enable cities such St. Petersburg, which has an aggressive reuse program but large quantities of
available wet-weather flows, to maximize their reuse efficiency.

Stormwater
The feasibility of expanding stormwater reuse should be investigated as an alternative water source.
It may be possible to blend stormwater with reclaimed water at a minimal treatment cost or to
develop large-scale stormwater facilities to provide water for selected uses.
