  1. Brine Disposal Strategies in Inland Southern California(Santa Ana River Watershed) Rich Haller, P.E. Program Manager, Santa Ana Watershed Project Authority (SAWPA) April 2, 2004

  2. Outline • Santa Ana Watershed • Santa Ana Watershed Project Authority (SAWPA) • Integrated Watershed Plan • Desalters, Brine Disposal (Santa Ana Regional Interceptor) • SARI System Enhancements Program

  3. The Santa Ana River Watershed • Over 2,650 Square Miles • Over 5 Million Residents • Portions of 4 Counties • Orange County • Riverside County • San Bernardino County • Los Angeles County

  4. The Santa Ana River Watershed San Gabriel Mtns. San Bernardino Mtns. Chino Basin Los Angeles Santa Ana Mtns. Orange County San Jacinto Mtns. Lake Elsinore/ San Jacinto Watershed Pacific Ocean

  6. Population Trendsin the Santa Ana Watershed • Additional 2.1 million people 2000-2025 • Additional 4.6 million people 2000-2050 Source: Center for Demographic Research California State University, Fullerton

  7. What is SAWPA?SAWPA Member Agencies & Other Stakeholders Other Stakeholders • 97 Water-related Agencies • 4 Counties • 59 Cities • State water, environmental, and regulatory agencies • Federal agencies • Other Special Districts • Special Interest Groups • Over 5 million residents

  8. Integrated Watershed Plan A collaboration of all watershed stakeholders to plan: Brine Line (SARI) Use Wetlands & Environment Water Resources

  12. Preliminary Cost and Timeline • Preliminary Costs are estimated at $160M* • The project planning will take about 1 year • Project construction would take 5 to 8 years • The project could be on line by 2010 * In November 2003 dollars

  13. Why are you doing this project? Gets the Salt Out • Improves water quality and supply • Maintains river quality • Reduced ocean discharge volume • Makes groundwater improvement in Orange County more effective

  14. Why are you doing this project? Treatment of the future • Improves water reclamation • Expands treatment system capacity in OC • Makes upgrading to secondary treatment quicker • Better treats discharges at their source
