  1. RECLAIMED WATER IN SOUTHWEST FLORIDA; THE BALANCING ACT AWRA 19th SWFWR Conference Howard S. Wegis, Staff Engineer, Lee County Utilities November 20, 2009

  2. LCU HISTORY OF DEMANDS AND PRICING; FROM LIABILITY TO COMMODITY • LCU and Most Other Utilities Developed the System Following a Bulk Use Model, Cape Coral Follows Residential Reuse Model • 1980’s-Early1990’s Focus on Disposal, Reclaimed Water Viewed as a Liability, Provided Free of Charge or Nominal Rate • Mid-1990’s Reclaimed Water Becomes Accepted, Demand Increases Charge Nominal Fee for Delivery • Mid to Late 1990’s Wet Weather Disposal Becomes an Issue, Reduce Rate to Promote Use • Late 1990’s Continued Growth and Demand, Return to Standard Rate • Early 2000’s Explosive Growth, Extended Drought, Reclaimed Water Becomes a Commodity. • Mid-2000’s Regulators Begin to Discuss Conservation Rate Structures For Reclaimed Water • Late 2000’s Downturn in Economy Does Not Effect the Demand for Reclaimed Water, Even With a Rate Increase in 2007, Or Was it Due to a Lack of Rain

  3. DEMAND AND PRICING VS RAINFALL Return to Standard Rate Demand Increases in Downturn Disposal Issues Reduce Rate Explosive Growth and Demand

  4. DEMAND FOR RECLAIMED WATER • Apparent Inelastic Demand • Use Continues to Rise Through Rate Hike • Demand is Rainfall Driven

  5. AVAILABLE RECLAIMED WATER VS IRRIGATION DEMAND

  6. LEE COUNTY FUTURE IRRIGATION DEMANDS

  7. THE NEED FOR MANAGEMENT OF THE RESOURCE

  8. MANAGING THE RESOURCE TO ACHIEVE SUSTAINABILE UTILIZATION • Develop Seasonal Storage • Reservoir • ASR • Supplement the Supply • Utility Provided • Customer Provided • Wet Weather Disposal • Deep Injection Wells • Surface Water Discharge • Have a Contingency Plan • Diversify Customer Base • Indirect Potable Reuse • Interconnects

  9. DIVERSIFY END USE TYPE • Large Percentage of Use on Golf Courses • Reduce Disposal

  10. DISTRIBUTION OF LCU RECLAIMED WATER SITES

  11. Waterway Estates / City of Cape Coral Interconnect

  12. FORT MYERS BEACH / FIESTA VILLAGE INTERCONNECT

  13. THE REGULATORY MINEFIELD • Protection of Human Health • Crypto and Giardia • Coli form for Supplemental Wells • Protection of the Environment • TMDL’s • Numeric Nutrient Criteria • Micro-Constituents • Constituents of Emerging Concern • Water Resource Management • Potable Water Offsets

  14. THE FUTURE OF RECLAIMED WATER FOR LCU • Increased Regulation, Increased Treatment, Increased Cost • Regional Supplemental Supply • Increased Storage Capacities / ASR • Continued Bulk Customer Base or Phase in Residential Reuse • Consider Indirect Potable Reuse

  15. THANK YOU Howard Wegis, Lee County Utilities, wegishs@leegov.com
