State and federal laws require all urbanized communities to collect and treat their domestic and industrial wastes. Proper treatment and disposal of sewage is essential to protect public health and prevent pollution of the environment.

We have the additional incentive of protecting the nearby Suisun Marsh, which is one of the largest remaining brackish water marshes in the country and the largest single wetland on the Pacific Coast.

The Fairfield-Suisun Sewer District is highly regulated by numerous state and federal agencies, and regulatory compliance is an essential component of the District's operations. Air quality is regulated by the Bay Area Air Quality Management District and the California State Air Resources Board. Quality of both wastewater and stormwater is regulated by the Regional Water Quality Control Board, and biosolids are regulated by the U.S. Environmental Protection Agency.

Because the District discharges into the environmentally sensitive Suisun Marsh, it meets extremely stringent effluent-quality requirements. The District’s treated effluent must essentially meet the profile for drinking water. Our diligent pretreatment and pollution-prevention practices enable us to fulfill those obligations.
