Operations and Maintenance
The City’s 5.0 million gallon per day (MGD) Wastewater Treatment Plant treats over 1.1 billion gallons of wastewater a year. This highly advanced treatment plant produces tertiary treated water which exceeds CA Title 22 drinking water standards. A portion of this treated water is presently discharged off-site to supply irrigation water to local parks and medians. In addition some of this water is sold for industrial use and to developers to assist in development.

The Wastewater Treatment Plant is staffed by state certified operators who are responsible for receiving, treating and disposing of the treated wastewater. The plant is continuously monitored by staff to ensure it is in compliance of all Federal and State discharge requirements.

Pretreatment Program
The City's pretreatment program is mandated by the Environmental Protection Agency (EPA) through the State of California's office of Water Quality. The purpose of the program is to monitor commercial and industrial discharges into the City's collection system. These discharges when not monitored have the potential of causing a process upset at the treatment plant or a "pass through" of pollutants that could harm the environment. Commercial and industrial businesses are required to be regularly inspected for compliance with EPA's strict standards.

The City of Brentwood’s Collections Division is responsible for cleaning storm drains, catch basins, and making repairs on residential laterals. Sewer lines are cleaned and camera inspected all year long to prevent Sanitary Sewer Overflows or SSO's.

Storm Water
Storm water is rain that falls on roofs or paved areas like driveways, roads and footpaths. This water is carried away by a system of storm water pipes and drains. It eventually ends up in our groundwater, lakes and ponds and the ocean. As rain falls to the ground, it comes in contact with pollutant sources that increase the potential for pollution of the runoff that flows into the storm drain system. Storm drain maintenance consists of cleaning 5,180 catch basins which are inspected and cleaned yearly.

The Regional Water Quality Control Board (RWQCB) requires cities and counties to conduct storm water management programs. The objective of these programs is to minimize the release of pollutants into the environment that pose a significant threat to local creeks and aquatic life.
