Status Proposed
Description
This project is a Reverse Osmosis (RO) facility to be co-located with the City of Punta Gorda's existing 10 mgd water
treatment facility. The RO facility would provide 2 mgd of treated brackish groundwater for blending with treated
surface water to reduce levels of Total Dissolved Solids (TDS). This project would also provide water to the four county
region (Charlotte, Sarasota, Desoto, and Manatee) through the Peace River Manasota Regional Water Supply
Authority's Phase 1A Interconnect (H069). Project components would include final design\permitting and construction.
Benefits
Construction of the RO facility for brackish groundwater treatment will provide a blending source to reduce levels of
TDS, which would improve the quality and seasonal reliability of the surface water treatment facility. The brackish
water could be used as an alternative source and could potentially serve as a future recovery strategy for proposed
MFLs on Shell Creek. The City has indicated in their application this water would be available to the Peace River
Manasota Regional Water Supply Authority.
Costs
The City estimated the total project cost at $36,700,000. The City budgeted $1,000,000 in FY2009 for the project, prior
to submitting a District funding request. The total District eligible cost through construction is estimated at
$35,700,000, with $17,850,000 in funding requested. The anticipated District FY2010 funding is scheduled as:
Governing Board $1,000,000, Manasota Basin Board $500,000, and the Peace River Basin Board $270,000.
Additional Information
The City currently has an interlocal agreement to transfer 1 mgd under the Authority's GAP permit. The GAP permit
expires on January 30, 2013. This project, along with the development of an off-line reservoir, are under examination
as part of an MFL recovery strategy for Shell Creek. The 2 mgd RO facility may employ some of the City's existing
ASR wells transitioned into brackish water supply wells. A deep injection well will be required to dispose of RO
concentrate. The treated groundwater will be used conjunctively with surface water when TDS levels are high during
periods of drought. The RO facility may be incrementally expanded to 8 mgd in future phases, based on the
permittability of brackish groundwater sources. Additional aquifer performance data will be required to determine total
groundwater availability in the area. Future phases of the RO facility may also be designed for the treatment of surface
water with high TDS levels.
