4. California ---No More “New” Imported Water Supplies with theHistoric Legislative Water Deal! • Water shortages likely in the future because Colorado River and Sacramento River “delta” supplies fully allocated! • State Water Plan: Conservation, water recycling, groundwater treatment and stormwater capture key strategies in urban areas. • Seawater desalination a relatively small percentage of solution but will be important in some coastal communities. • Water/Wastewater utilities will increasingly focus on renewable energy as a result of climate change laws and regulations.

5. $11.1 Billion Water Bond $1 billion for water recycling and $1 billion for groundwater clean up And another $1.4 billion for regional water supply projects

6. California’s Water Future Investments Next 20 years • Sources of New Supplies: • Conservation Technologies - 40% ($1.5 billion) • Recycled Water – 30% ($8-10 billion) • Groundwater Storage and Cleanup Technologies – 25% ($6-7 billion) • Seawater Desalination of New Water Supplies – 1% to 3% ($2 billion) • New Dams – 2% to 5% (if built about $10-12 billion)

7. Recycled Water Uses • Governor’s Recycled Water Task Force 2003 • California Water Board Recycled Water Policy 2009 • Water Bond $1 billion for Recycled Water • Metropolitan Water District Regional Water Plan California – reuse and recycling will double in volume by 2015 and then double again by 2020!

8. Applications Landscape Irrigation Agricultural Irrigation (Edible & Non-Edible Crops) Industrial and Commercial Environmental Uses Non-Potable Urban Uses (Urinal Flushing in High Rise Buildings) Groundwater Recharge Potable Water Supply Augmentation

9. Federal EPA and Bureau of Reclamation Partnership on Recycled Water Uses • Use Watersense and DOE Energy Star branding models • Promoting new innovative uses of recycled water • Encourage recycled water use at all federal facilities

10. What is Possible with Water Reuse? Answer: Virtually Anything Given Current Technology With MF/RO/UV/AOP, Can Produce Water that is Virtually Pure Dihydrogen Monoxide Problem is that Technology has Surpassed our Ability to Communicate Effectively with Public Need to Resolve Issues with EDCs/PPCPs

11. Significant Trends in Water Reuse Reuse is Gaining in Prominence Around the Globe (e.g., Australia, Singapore, South Africa, Israel, Spain, Belgium) Technology Marches Forward with AOP & MBRs Constant Challenge in Public Acceptance Arena Research Focus is Now Global Climate Change and Energy are Significant Emerging Issues Progress Being Made Internationally on Indirect Potable Reuse Front

12. Potential for Water Reuse Approximately 11.2% of municipal wastewater effluent in the U.S. is reclaimed and beneficially reused About 34.9 bgd Municipal Effluent in the U.S. 11.2% Reclaimed

13. EnhancedSource Control 70 mgd 70 mgd Reverse Osmosis (RO) Ultraviolet Light (AOP) 86 mgd Microfiltration (MF) SecondaryTreatment Purified Water OCSD Secondary Effluent Natural soil filtration with hydrogen peroxide Backwash OCSD Plant 1 Brine OCSD Outfall

15. IEUA Recycled Water Production Cycle Primary Secondary Tertiary Industrial Pretreatment & Source Control 95% TOC Removal to 7.0 mg/L Avg. Influent TOC Avg. 165 mg/L Industrial & Brine Export Distribution System Groundwater Blend & Hold Soil-Aquifer Treatment 50% TOC Removal to ±1 mg/L 75% TOC Removal to ±2 mg/L

16. Exceptional Recycled Water Quality • Pre-Treatment Program • Manages Significant Industrial Users (SIU) • No Drugs Down the Drain Program • Industrial & Brine Export to NRWS • Longstanding Treatment Facility Performance • Outstanding NPDES & T-22 Compliance Record • 100% Compliant for 2008 • Exceptional Nitrogen and TOC Removal • No Issues with Emerging Constituents of Concern

17. Recycled Water Usage Actual and Planned

18. Recycled Water Use FY08/09 Projected FY11/12 (3-Year RW Business Plan) 3-Years

19. Wastewater Utility Goals Three Products: • Recycled Water • Biosolids/ Composting • Renewable Energy

20. IEUA’s Energy Strategy • Since 2001, goal has been to maximize renewable energy, optimize energy usage • Significant investments made in biogas generation, energy efficiency, green building (first platinum LEED) • Go “100% Renewable” by 2020 • Pursue New Renewable Technologies

21. IEUA Innovations to Address Energy Needs Maximize Efficiency • Constructed the nation’s first platinum LEED-rated headquarters by a public agency (2003) Sustainability and Diversification • Biogas production from anaerobic digesters • Installed a total of 16.5 acres of solar panels in 2008 on four Agency’s sites

22. Water and Energy Nexus---About 20% of the Electrical Energy Use is Related to Water • Renewable Energy Strategies • Climate Change • Key Driver to the Future Cost of Water

23. State Water Project Pumping Facilities

24. Electricity Use for Water System Components in Southern California Groundwater Supply 6% Local Distribution 9% Waste Treatment 14% Imported Water Supply 71%

25.

26. Solar System at IEUA Water Recycling Plant (Went live 11/28/08 at 1300 hours)

27. Solar Summary • 3.5 MW of Solar installed at 4 sites in just 4 months • Financing – Power Purchase Agreements (PPA) used – No capital burden on Agency • No maintenance responsibilities for IEUA
