Downey Water Department

YOUR WATER SUPPLY Downey’s groundwater is pumped from the Central Groundwater Basin. The Central Basin is a chain of massive herbal aquifers below the ground that reaches from Los Angeles to Orange County. The Central Groundwater Basin gets herbal inflows from the conservation of rainfall and snowmelt, artificial inflows from imported and recycled water, in addition to groundwater underflow from adjacent basins. The City of Downey with no trouble overlies the Central Basin. Groundwater from the Central Basin is pumped from 20 wells located inside the City’s limitations and presents the City with its important source of potable water. Spreading grounds located on the primary inflows from the Rio Hondo and San Gabriel Rivers of the Montebello Forebay, permit water from various resources to artificially seep down into the Central Basin aquifers. As floor water slowly percolates via the ground to the aquifers, the floor acts as a natural filter to easy the water.
