1 Welcome to the Advanced Water Purification Facility

2 SAN DIEGO IS DOWNSTREAM San Diego

3 Water Supply Challenges: Limited local & imported supplies Population growth Bay Delta constraints Natural disaster risk Rising imported water costs Recurring drought $1,400 $1,200 $1,000 $800 $600 $400 $200 $-

4 What is being done Regional: Local: Water Conservation Water Conservation Desalination (SDCWA) Groundwater Development Recycled Water Potable Reuse (Pure Water)

5 Pure Water: Our Opportunity Phased multi-year program that uses proven technology to provide a safe, sustainable, and high quality water supply Provides a locally controlled, drought-proof water supply to significantly improve our water reliability A cost-effective investment for San Diego s future water needs

6 Here s How it Will Work

7 Pure Water Works for San Diego Demonstration Project confirmed the viability and safety of water purification Produced 1 million gallons a day Conducted 28,000+ laboratory tests to date Water met all drinking water standards Exceptional water quality comparable to distilled water Energy use is comparable to imported water and cost is approximately $1,700 1,900 per acre-foot City Council Point Loma permit application approval, Nov. 18, 2014

8 A look inside This video explains the treatment processes you will see on the tour

14 Others Are Doing It Successfully Orange County, CA Fairfax, VA Operating since 2008 Places purified water into the groundwater basin Recently expanded to 100 MGD Operating since 1978 Recycled water is added to a surface storage reservoir Potable water supply source for Fairfax County, VA

15 Ratepayer Costs (Millions) Pure Water San Diego Saves Money $2,000 About $250 million in ratepayer savings $1,500 $1,000 System upgrades w/o Pure Water Pure Water San Diego $ Pure Water Secondary

16 San Diego Tap Water Cost Comparison Per Gallon Cost of Other Liquids (July 2015) Milk $ 3.49 Coffee (AM/PM) $10.67 Soda (Coke) $ 3.99 Vended water $ 0.35 Gallon of store brand water $ 1.09 Gallon of name brand water $ 1.49 San Diego tap water* $ delivered *Based on average monthly water bill at 12 HCF (hundred cubic feet)
