Water Quality

State law requires water retailers to provide information to their customers about the quality of their drinking water and the reliability of the water supply. The City of Chino Hills is dedicated to providing you with a safe and reliable supply of high-quality drinking water. Prior to reaching your faucet, your water undergoes an extensive treatment and testing process as dictated by the State Water Resources Control Board (SWRCB) and the U.S. Environmental Protection Agency (USEPA).
