Water Pollution Control Plant (WPCP)

The City of Chico operates and maintains a modern 12 MGD capacity, secondary treatment, activated sludge, wastewater treatment plant with future expandability to 15 MGD capacity. The plant operates under strict waste discharge requirements permitted by the California Water Resources Control Board. The discharge location for the treated wastewater (effluent) is the Sacramento river. The WPCP runs a state-certified, full environmental laboratory for daily testing of the plant effluent to ensure that its quality meets state standards.

The WPCP operations staff operate and maintain fifteen sewer lift pump stations that pump wastewater from areas in the city that do not have the ability to gravity flow through the wastewater collection system.

The WPCP operates a 1.1 Megawatt, Solar Photovoltaic facility providing electric power to the WPCP, which reduces the plant's use of utility power by approximately 35%. This solar facility is one of the largest in the nation to be installed at a wastewater treatment plant. Also, a 335-kilowatt co-generator is on site that uses methane produced in the plant process as a fuel source to produce electricity which is used at the WPCP.

 

Private Sewer Lateral Problems

The property owner owns and is responsible for maintaining the entire sewer lateral from the plumbing in the property owner's buildings, up to and including the connection to the sewer main in the street. If there is a clog in the sewer lateral, it is the property owner's responsibility to clear it. City crews are not allowed onto private property in order to clean or maintain privately owned sewer laterals.

The Chico Industrial Pretreatment Program (CIPP) is located at the WPCP. The CIPP program permits and controls wastewater discharges from businesses and industry that could potentially be harmful if allowed to be discharged into the environment.
