Located in Martinez, the plant has a treatment capacity of 54 million gallons per day (mgd) and 240 mgd of wet weather flow. The Plant Operations Building houses the Control Center, a state-of-the-art computerized system that monitors and controls every phase of the treatment process. The facility is staffed 24 hours a day, 365 days a year.
Wastewater moves through the District’s 1,500 miles of sewer lines, finally arriving at the plant’s headworks to begin treatment. Most of the wastewater is treated to a secondary level, disinfected by ultraviolet light, and then discharged into Suisun Bay. Approximately 600 million gallons per year are treated to a tertiary level through additional filtration and disinfection before being distributed as Recycled Water for landscape irrigation, industrial processes, and plant operations.
