Anderson Water Pollution Control Plant (WPCP)

 Anderson operates and maintains a modern Class IV, 2 million-gallon per day (MGD), tertiary wastewater treatment plant.

Wastewater is conveyed to the plant by gravity and four pump stations through a system of pipes (38 miles) to the plant. The plant operates under strict waste discharge requirements permitted by the California State Water Resources Control Board. Operators working in the plant are required to be certified by the State Water Resources Control Board at level requirements pursuant to a Class IV plant to ensure competency in the field of wastewater treatment.

The City serves its customers by protecting public health and the environment through reliable and safe conveyance, treatment and disposal of wastewater in the most cost-effective manner possible, now and into the future.
