What is wastewater?

Wastewater, also called sewage, is the water from residences and businesses that flows down the drains of sinks, showers and baths, and toilets.

Who operates and maintains the treatment plant?

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.

Is water from our streets and gutters treated at the wastewater treatment plant?

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

What harm can a few drops do?

What harm can a few drops of antifreeze or paint do in such a large volume of water as the Suisun Marsh? Unfortunately, those and other contaminants and toxins can cause plenty of harm, even in minute amounts. Just a few parts of contaminant per billion—equivalent to just one drop of toxic fluid added to a swimming pool—can threaten the aquatic organisms, fish and birds that inhabit the Suisun Marsh.

Is the sewage system able to continue operating during an electrical power failure?

Yes. We have backup power facilities for all systems.

Where does the water go after the District treats it?

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.

How much wastewater does the District treat?

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.

What happens to the solid byproducts of sewage treatment?

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.

What is stormwater?

Stormwater is water that collects in the gutters of streets, from rainwater as well as other sources, including runoff from sidewalks, driveways and landscape watering. Stormwater is also known as urban runoff.

Where does stormwater go?

Stormwater flows into storm drains, and then runs untreated to your local creeks and the Suisun Marsh. That’s why you should prevent automotive antifreeze, oil, solvents, construction debris, liquid fertilizers, weed killers, insecticides, leftover paint, chlorinated pool water and other contaminants from reaching curbs and flowing into storm drains.
