PICTURE Water Independence Now Program Presented to WateReuse – LA Chapter August 13, 2013

420 square miles 43 cities Population = 4 million (over 10% of California ’ s population) 250,000 acre feet of groundwater annually Groundwater provides 40% of water supply

Imported Water Supply Challenges CA Bay Delta: Environmental Land Subsidence CVP CVP Seismic Vulnerability Mokelumne River Mokelumne River Aqueduct Aqueduct Colorado River Drought: Colorado River Drought: Hetch Hetch Hetchy Hetchy Los Angeles Los Angeles System System Aqueduct Aqueduct Colorado River Colorado River SWP SWP Aqueduct Aqueduct Lake Mead’s water level has dropped more than 100 ft since 2000.

WRD ’ ’ ’ ’ s WIN Program will eliminate demand for imported water to demand for imported water to replenish groundwater

Benefits of Groundwater • Local reliable & sustainable supply • Drought protection • Cost-effective 5

A Sustainable Solution THE CORNERSTONE of the WRD’s Water Independence Now Program, which seeks 100% independence from imported water. REPLENISH the area’s groundwater reservoirs with local REPLENISH the area’s groundwater reservoirs with local resources. CONSERVE water resources, save money, and create a local water source for residents. CREATE a sustainable solution to potential water supply shortages.
