  1. City of San Diego

    San Diego Water Innovation Opportunities 

    February 2014 – a look ahead Halla Razak, P.E.
  2. San Diego Public Utilities Department… Delivers high quality drinking water, collects and treats wastewater, produces delivers recycled water, and generates green energy– everyday Maintains and operates extensive infrastructure Keep rate-payer affordability top of mind
  3. San Diego Water/Wastewater Facts
  4. California Water System Highlights 77% of the City of San Diego’s water is imported 26% Bay Delta 51% Colorado River 23%Local Supplies and Conservation
  5. City of San DiegoWater System Overview Water System Three major treatment plants over three service areas Strategically located reservoirs to capture/store local water supply Complex system with more than 3,300 miles of pipelines Miramar Water Treatment Plant Alvarado Water Treatment Plant Otay Water Treatment Plant
  6. Water Supply Availability Limited local supplies Imported water at risk as competition for the resource rises Recurring drought Population growth Regulatory constraints Natural disasters/climate change
  7. Imported Water Costs Imported water costs have doubled since 2008
  8. What Options Does San Diego Have? Regional: Importing from State Water Project and Colorado River Desalination (SDCWA) City of San Diego: Water Conservation Groundwater Development Recycled Water Indirect Potable Reuse (Pure Water) 8
  9. 83-mgd of Pure Water: Our Opportunity Initial phase: 15 mgd of purified water to San Vicente Reservoir (7 - 8% of local supply) Our purest source of raw water Reliable and locally controlled Drought proof, climate independent More control over local investments Add economic benefit to local industry membrane companies, construction jobs Decreases reliance on imported water Reduces ocean discharge
  10. Wastewater System Overview Wastewater System Geographically distributed Pt. Loma is the hub Collect, treat & dispose wastewater from San Diego & 12 other agencies Pt. Loma operates with a 5-year modified permit Recycled Water System 3 Pump Stations/80 Miles of Purple Pipes North City Water Reclamation Plant MetroBiosolids Center (MBC) Point Loma WWTP South Bay Water Reclamation Plant
  11. Pure Water Supports Permit Renewal Long-term program specifics Permit renewal application due January 2015 Committing to investment in Pure Water could result in substantial savings at Pt. Loma Reduces treated water discharge volume into ocean
  12. San Diego Water at a Fork in the Road Pure Water Secondary Treatment San Diegans will save over $2.5 billion dollars over the life of the Pure Water solution
  13. San Diego Water
  14. Pure Water Program Elements Pure Water demonstration program Permit package development Regulatory and legislative initiative Outreach program expansion to include enhanced public engagement and education Financial plan Capital program implementation
  15. Next Steps Request Council Resolution for Pure Water:  Spring 2014 Invest in outreach education: Spring 2014 Roll out aggressive conservation program: Spring 2014 Solicit services for program manager: Summer 2014 Prepare waiver application: Fall 2014 Optimize scenarios & costs: 2014/15 Work with elected officials, regulators, and stakeholders to develop consensus and secure approvals: 2014/15
  16. Back-up Slide
  17. Investing in our Water Future We know that: Imported water rates rising Need to maintain/operate existing systems Ongoing water & wastewater capital improvements 2015 Pt. Loma permit renewal Pure Water implementation at 15 mgd 46 mgd Point Loma offload
  18. Pure Water Process
