Water Quality Compliance
In compliance with the Environmental Protection Agency’s (EPA) Lead and Copper Rule Revisions (LCRR), Water Division staff completed a year-long lead and copper service line inventory to ensure the safety and quality of drinking water for Cerritos residents. The division has determined that there are no lead or galvanized service lines requiring replacement.

The City's Water Utility maintains approximately 16,000 water service connections Citywide including wells, system reservoirs, water transmission lines, fire hydrants and a recycled-water distribution system.
Water Supply
Cerritos water is tested regularly and continually meets or exceeds all state and federal quality standards. The City's water supply is from two sources — the Metropolitan Water District (MWD) and local groundwater.
The City produces groundwater from three deep wells in Cerritos, which are drilled to a depth of 700 to 1,000 feet. In 2008, these groundwater sources supplied about 3.6 billion gallons, or 98.6 percent, of the City's total water supply. The water system also includes one 12-million-gallon reservoir and two six-million-gallon reservoirs that help the City meet demand during peak periods.
Water is distributed to consumers through a City-owned system of pipes, ranging in size from four inches to 36 inches in diameter. Approximately 181 miles of pipe supply water to an estimated 16,000 homes, businesses and industrial sites. Water meters measure the quantity of water used during a billing period. The City performs a water meter change-out program to ensure meters accurately reflect water usage.
Annually, the City prepares and provides all water customers with a Consumer Confidence (Water Quality) Report detailing analysis results of all water samples collected during the year. For a copy of the report, or for any other water-service related questions, call (562) 407-2674.
The Water Utility's hours of operation are from 8 a.m. to 5 p.m. Monday through Friday. The Water Division provides emergency water service on a 24-hour basis. To report water leaks in City streets or a water-related emergency, call the City's answering service at (562) 860-4018 after hours.
