Gap Analysis Including North Fort Myers and Lehigh Acres area

Source Water and Water Treatment Plants

North Service Area

Expand North Lee WTP to 15 MGD

Increase brackish groundwater supply

Decommission Waterway Estates WTP

Increase connectivity amongst service areas

Olga Service Area

Expand Olga WTP capacity to 10 mgd

Improve river supply with ASR (limitations w/2 ASRs)

Introduce brackish groundwater supply

Increase connectivity amongst service areas

Source Water and Water Treatment Plants (Cont)

South Service Area

Replace Green Meadow 9 mgd with new 14 mgd WTP

Maintain capacity at Corkscrew and Pinewoods WTPs

Increase treated water ASRs (success at Corkscrew w/5 ASRs)

Investigate groundwater to groundwater ASR

Investigate connectivity with other raw water supplies

Increase connectivity amongst service areas

Distribution Connectivity – 29 identified major pipeline projects

Wastewater Service Improvements

Three Oaks Service AreaDecommission San Carlos WWTP and convey flow to Three

Oaks WWTP

Expand Three Oaks WWTP or consider a new regional WWTP

Waterway Estates Service Area and High Point Service Area

Decommission both WWTP’sConvey wastewater flow to North Fort Myers FGUA service area

North Fort Myers FGUA Service AreaPurchase North Fort Myers FGUAExpand WWTP capacity

Reclaimed Water

West (Fort Myers Beach/Fiesta Village) Service AreaDeep Injection Well to eliminate river discharge from Fiesta

Village WWTPReclaimed Water ASR/DIW for seasonal water managementInterconnecting pipeline between facilities to optimize reclaim

utilization

Three Oaks Service AreaDevelop supplemental supply for reclaimed water system to

better meet demand during dry season(under design)

System-wide82% reclaimed utilization of WWTP effluent Continue to seek strategic opportunities to offset potable water

demand

Next Steps

Further study storage options to maximize offset of potable water through reliable reclaim water system to further reduce disposal of this commodity.

Maximize benefit of alternative water sources and reclaimed water for overall water management

Beyond disposal of reclaimed waterFind the best “value” residential, industrial,

recreational direct offset of potable water Land use and construction regulations in new

development to enhance stormwater retention and Florida-friendly landscape
