  17. 17. Key Delta Risks Fishery Declines Delta smelt Seismic Risk Flooding Risk Bay Area Faults Jones Tract (2004) 17
  18. 18. We face significant losses of spring snowpack • Less snow, more rain • Particularly at lower elevations • Earlier run-off • More floods • Less stored water By the end of the century California could lose half of its late spring snow pack due to climate warming. This simulation by Noah Knowles is guided by temperature changes from PCM’s Business-as-usual climate simulation. (a middle of the road emissions scenario) Knowles and Cayan 2001 18
  19. 19. Water Resource Impacts Decreasing snowpack, earlier snowmelt More rain - increased runoff – altered water quality Increased demand & evaporation– due to higher temperatures Increased saltwater intrusion – due to sea level rise Increased salinity in Delta 19
  20. 20. Current Drought Condition in San Diego County Metropolitan Water District (MWD) will allocate supplies 13% cut from MWD starting July 1 Water Authority allocating supplies to its 24 member retail agencies Regional shortage: 8% Cutbacks to agriculture: 13% to 30% Financial penalties in place “Drought Alert” condition Mandatory water use restrictions 20
  21. 21. Mandatory Water Use Restrictions Irrigation restrictions Limits on number of days/duration/prohibited hours Stop runoff/time limits to repair leaks Ornamental water fountain/feature use prohibited Unless using recycled water Washing paved surfaces prohibited Car washing: positive shut-off nozzle or commercial site that re-circulates/re-uses water Restaurants: water served only upon request Lodging: must offer guests option of not laundering towels and linens daily Construction purposes: use recycled or non-potable For specifics on local regulations: www.sdcwa.org 21
  22. 22. CY 2010 Recommended Rates and Charges— Summary Overall increase is 18.1% starting September 1, 2009 Impact on a typical household is $5.80/month Increase is below MWD’s treated water increase of 21.1% Wholesale full-service, treated water rate is $905/acre-foot Average single-family household of four with an irrigated landscape uses ½-acre-foot per year 22
  23. 23. Diversifying San Diego County’s Water Supply Portfolio 1991 2010 2020 Local Supplies Dry-Year 40% QSA Transfers 95% Supplies 2% Local Supplies 20% 16% MWD Supplies QSA 29% Supplies 31% MWD Supplies 62% Metropolitan Water District Seawater Desalination Imperial Irrigation District Transfer Local Surface Water All American & Coachella Canal Lining Recycled Water Conservation Groundwater Dry-Year Water Transfers 23
  24. 24. Diversification Strategy is Working Colorado River Quantification Settlement Agreement (QSA) 155,000 AF in FY 2010 Ramping up to 280,000 AF/YR by 2021 Expanding development of local supplies Recycled water Groundwater Seawater desalination Conservation $3.7 billion Capital Improvement Program Historic regional infrastructure investments 24
  25. 25. Enhancing Colorado River Supplies to San Diego QSA Supplies (Colorado River) Imperial Irrigation District transfer (45 to 75 years) Canal-lining projects (110 years) All-American Canal Lining Canal-lining project Coachella Canal Lining Provide 129,000 acre-feet combined in 2009 280,000 acre-feet annually by 2021 25
  26. 26. All American Canal Lining 26
  27. 27. Desalination Benefits: Challenges: New locally-controlled Higher capital and potable water supply operating cost (similar to the cost of recycled Drought-proof supply water) Improved water quality Availability of coastal Reliable supply (proven sites for desalination technology) Intake and Discharge Economies of Scale Permitting (impacts to marine life) Higher energy use relative to other water resources 27
  28. 28. Carlsbad Desalination Project Private 50 mgd local desalination project being developed by Poseidon Resources Located at the Encina Power Station in Carlsbad Water purchase agreements with nine SDCWA member agencies Major permitting hurdles: Coastal development permit (cleared) Lease amendment from SLC (cleared) Discharge permit with RWQCB (now cleared) Work continues on finalizing the configuration of distribution system Projected on-line date: 2012 28 28
  29. 29. Camp Pendleton Seawater Desalination Project Proposed capacity between 50 and 150 mgd Feasibility Study nearing completion Subsurface and open ocean intake options Potential integration with existing Camp Pendleton systems Next Steps Planning Agreement with MCBCP Complete Environmental Review Complete Preliminary Design Earliest On-line Date - 2018 29 29
  30. 30. Seawater Desalination: Mexico and South County Joint study with Mexico and U.S. Colorado River water agencies Rosarito Beach site 25 to 50 mgd South San Diego County Follow-up to 2005 Water Authority study Site north of border, near International Outfall Up to 25 mgd 30
  31. 31. What about Water Recycling? Non-potable Recycled Water: is a high-quality, drought-proof water supply is an environmentally sensible use of a limited resource replaces potable water use for the irrigation of landscapes, crops, golf courses, freeways, etc. is not impacted by potable water restrictions/ aqueduct shutdowns Will represent 6% of the supply portfolio in 2020 31
  32. 32. Indirect Potable Reuse Need creative solutions for San Diego - Accommodate small groundwater basins - Reservoir Augmentation Coordination with Regional Board & California Department of Public Health Protect public health and water quality Public acceptance 32
  33. 33. City of San Diego Indirect Potable Reuse (IPR)/Demonstration Project Advanced Water Treatment process Tertiary Detention Reverse Pipeline Treatment Treatment Ultra- filtration + Osmosis + UV + Peroxide + Chlori- nation + Time in Reservoir + at Drinking Water Plant 33
  34. 34. Capital Improvement Projects Emergency Storage Program Major Projects Completed or under construction Asset Management 34
  35. 35. $3.8 Billion Capital Improvement Program (1989-2030) System of facilities to: $3.8 Billion CIP Meet regional demands Meet emergency demands Support Emergency Common to both: Demands 34% Dams and reservoirs Support Regional Pipelines Demands Pump stations and 66% flow control facilities Treatment Plant & Hydroelectric regional assets 35
  36. 36. Water Storage – Olivenhain Reservoir Completed in 2003 at a cost of $198 million, the Olivenhain Reservoir stores 24,000 AF of water, enough water for 50,000 families a year 36
  37. 37. Water Storage – Lake Hodges Projects Will provide 20,000 AF of water storage for emergency use, enough for up to 40,000 homes, and annually generate enough electricity for 26,000 homes 37
  38. 38. Lake Hodges Projects Construction of the Lake Hodges Projects began in 2005 and is anticipated to be complete in late 2010. 38
  39. 39. 39 39
  40. 40. Water Storage – San Vicente Dam Raise Will increase lake capacity by 150,000 AF from the current 90,000 AF Total project cost is $568 million Construction will be complete by the fall of 2012 Once finished, depending upon rainfall and water supply and demand, will take 2 – 5 years to fill to capacity 40
