Drought Response and Recycled Water Outlook for 2016 Hossein Ashktorab, Ph.D. Recycled and Purified Water Unit Manager February 26 th , 2016

Who we serve 2,000,000 people 15 cities 4,700 direct well owners 13 local water providers

Economic Impact of Water Shortage Water reduction 10%-30% Decrease in local sales losses of $900 million to $10 billion !!!! 3

Risks to Water Supply Reliability Lake Oroville 2011 • Ongoing/ severe droughts • Climate change • Reduced import of water Lake Oroville 2014 • Population growth 4 1

Recycled Water Can Fill the Gap  Reusable source  Locally-controlled source  Purified through treatment  Drought-proof  Replicates natural water cycle

DPR Could Be Future Complement to IPR • Less infrastructure • Purified water required: pumped into • Pipelines shorter How • No injection wells raw water line Program would or ponds • Treated at DPR • Capitalizes on Benefits drinking water drinking water work? treatment plant treatment ozonation/BAF plants • Simpler operations

RO Concentrate Management Options • Discharge to existing shallow water Bay outfall with dilution water • Treatment wetlands, then discharge to the Bay • Pre-treatment to produce a brackish supply for wetlands restoration • Discharge to a sewer line that goes to a regional wastewater treatment plant • Discharge to deep Bay outfall
