3. SMWD Recycled Water Important part of the Water Reliability Planning Currently meeting 17% of demand Increase to 33%, utilize 100% of the wastewater at build out of the District Seasonal storage is required to meet the goals
4. Uses Current and Future recycled demands by agency Types Purple pipe use predominates today Future use includes indirect/direct reuse Additional supply available
5. Regulations Indirect/Direct Reuse OCWD Groundwater Replenishment is an indirect reuse project WateReuse Initiative under way to fund studies Regional Board State Water Resources Board Public Drinking Water
6. Current Supplies 11 treatment plants Current 43 MGD 17,700 AF recycled 30,800 AF ocean disposal San Juan Watershed 18,900 AF Outfall Aliso Creek 11,900 AF Outfall
7. Future Supplies 11 treatment plants Planned 48 MGD 44,100 AF recycled 10,100 AF ocean disposal SJBA San Juan Watershed 3,400 AF Outfall Aliso Creek 6,700 AF Outfall
8. Future Supply Projects Expansion of SMWD Chiquita WRP Expansion of El Toro WRP Expansion of MNWD/SMWD 3A Plant Coordination of flows between plants to optimize production SMWD Ortega Area seasonal storage reservoir IRWD Syphon Reservoir expansion
9. SMWD Ortega Area Seasonal Storage Provide seasonal storage to meet seasonal irrigation demands Allows for capture of flows currently being lost to the ocean Potential Regional Resource City of San Clemente City of San Juan Capistrano SMWD Indirectly Moulton Niguel Water District South Coast Water District Two Potential Sites Ortega Site – Previously Studied Trampas
10. Trampas Lake Reservoir and Dam
11. Site Location Ortega Study Site Chiquita WRP Trampas Canyon Dam Site
12. IRWD Syphon Reservoir IRWD Facilities Syphon Reservoir Existing 500 AF Proposed Expansion 5,000 AF Regional benefits
13. Proposed 5,000 AF reservoir
14. Financing State Water Resources Control Board 1% low interest loans for recycling projects just announced MWDOC/MWD Local Resources Program Proposed Bond Drought funding Local Capital Financing
15. Next Steps Confirm collective interest in maximizing recycled water use South Orange County Integrated Regional Water Management Plan Collective effort to ensure projects are listed and effectively ranked Initiate project partnership and participation discussions
