With weeks of rain pounding Los Angeles and the greater Southern California region, LADWP's significant investments in expanding stormwater capture infrastructure were paying major dividends in replenishing our groundwater basins. During the rainy season so far, from October 1, 2022 through January 17, 2023, LADWP estimated the cumulative amount of stormwater capture is approximately 41,900 acre-feet. That translates to about 13.6 billion gallons—enough water to serve 167,500 households for a year or equivalent to filling 20,700 Olympic size swimming pools.
Capital improvement projects such as the Tujunga Spreading Grounds Enhancement completed last year, and local community improvements like the San Fernando Valley Green Streets, have increased LADWP’s total stormwater capture capacity from about 64,000 acre-feet per year (AFY) in 2015 to over 82,600 AFY -- representing 55% of the way to achieving the City of Los Angeles’ 2035 goal of 150,000 AFY, or 48.9 billion gallons, of stormwater capture capacity.
