Potable and Recycled Water Storage Reservoirs
The District has 17 Potable water storage reservoirs with a total capacity of 47 million gallons to serve a customer water demand of approximately 10 million gallons per day. In the event of an emergency, this storage represents a supply of water for just over three days.
The District also has one recycled water storage reservoir with a total capacity of 5 million gallons.
Potable Water System
The District operates and maintains approximately 219 miles of potable water mains, 18 miles of recycled water mains, 1,650 fire hydrants and 13,500 customer service connections.
The District relies mostly on imported drinking water supplies from the Colorado River and from Northern California, which are delivered by our wholesalers, Metropolitan Water District of Southern California and Three Valleys Municipal Water District. The District also receives local groundwater from the Main San Gabriel Groundwater Basin.
The District has a total of 8 booster pump stations consisting of 22 booster pumps pumping water to various elevations throughout our service area.
Emergency Power Sources
In the event of a power failure, the District has portable emergency electrical generators to continue pumping water to the various elevations. The generators have the capability of meeting the power demands for the pump stations.
Automatic Meter Reading System
To control costs and improve customer service, the District utilizes automated meter reading (AMR). This system allows our personnel to read meters on both industrial and residential sides of the street from their vehicle as they drive their assigned route – they are able to read 3,000 meters per day as opposed to 500 manual reads.
