4.0 RECOMMENDATIONS


Recognizing the need to support the development of alternative water sources, the District
established the New Water Sources Initiative in 1993. In 1994, the District selected 12 cornerstone
projects for NWSI funding. The cornerstone projects include aquifer storage and recovery,
reclaimed water and stormwater reuse, water resources enhancement projects, and surface water
development. Four additional projects were awarded NWSI funding in 1995, bringing the total
number of NWSI projects to sixteen. Fifteen out of the sixteen NWSI projects are currently being
implemented. (The sixteenth project, the Lake Jackson/Josephine Watershed project, has been
canceled.)

Feasibility studies for several ongoing projects will help determine the potential for the
development of certain alternative water sources. The feasibility of indirect potable reuse will be
evaluated as part of the Tampa Water Resource Recovery Project. 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 and/or stormwater for wetland and wellfield rehydration.

This New Water Sources Initiative Annual Report was developed to summarize existing projects,
evaluate the availability of alternative water sources, and provide a framework for future project
selection. It is estimated that more than 200 mgd of alternative water sources, conservation not
included, are available District-wide (Table 2-16). Because conservation projects do not usually
meet the NWSI criteria of providing regional water resource benefits, it is recommended that
conservation projects funded at the local level under the Cooperative Funding Program. The
majority of the alternative water sources eligible for NWSI funding are located in the west-central
(Hillsborough, Pasco, and Pinellas counties) and southern (Charlotte, De Soto, Manatee, and
Sarasota counties) portion of the District.

Based on information presented in this report, the following recommendations are made regarding
future alternative water source development:

Seawater Desalination

The alternative water 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-water and surface-water
sources. Accordingly, 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 1995. 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.
