The District’s staff and Board of Directors administer and oversee all aspects of the District, including plant operation and maintenance; finance and planning; engineering; construction design and management; and regulatory compliance.

No. Water from our streets and gutters is discharged directly to our local creeks and Suisun Marsh without treatment.

Yes. We have backup power facilities for all systems.

Most of the water is discharged into Boynton Slough, southeast of our treatment plant. About 10 percent of the water is recycled for landscape irrigation.

The Fairfield-Suisun Sewer District treats an average of about 16 million gallons per day. That’s enough water to fill a football field to a depth of 50 feet.

Solids removed during the treatment process are thickened and treated in a closed vessel, through a process called ‘digestion' Methane gas produced as a natural byproduct of the digestion process is used to produce electrical energy. A ‘dewatering' process dries the solids, preparatory to proper disposal.
