Capture up to 28.6 billion gallons of water per year to replenish our aquifers.
Each day, 310 million gallons of water flow down the LA River and into the ocean. We evaluated how much stormwater runoff entering the ocean could be realistically captured from the LA River and used for water recharge of aquifers.
The studies reveal that approximately 28.6 billion gallons (or 88,000 acre-feet) of total groundwater recharge could be reclaimed per year through centralized capture and infiltration projects throughout the LA River watershed, resulting in a 14% reduction in our regional water import needs.
88000 Acre Feet = (88,000 x 325,851) = 28,674,888,000 Gallons
