Water Quality

The Quality of Your Water

Water quality is an important issue for water utilities and its consumers. Water quality regulations are ever changing and, as a result of the Safe Drinking Water Act Amendments passed by the Environmental Protection Agency in 1996, they are becoming even more stringent.


Valencia Water Company is dedicated to supplying its customers with safe and healthy drinking water. Valencia Water Company provides its customers with water that is in 100% compliance with all federal and state water quality regulations. Water quality samples are collected weekly, monthly, quarterly, and annually under the direction and guidance of the State Water Resources Control Board Division of Drinking Water (DDW). We work closely with DDW on all emerging water quality issues.


As part of maintaining a safe and reliable water supply, Valencia Water Company implements a stringent Cross-Connection Control Program. A cross-connection is an illegal connection between a potable water system and a non-potable water system. Valencia Water Company enforces a program that ensures protection of our potable water system.
