The Fairfield-Suisun Sewer District is a special district, a legally constituted governmental entity established to fulfill a specific function—in our case, wastewater and stormwater management in a multi-jurisdictional environment.
The District serves more than 135,000 residential, commercial and industrial customers and government agencies in central Solano County, about 40 miles northeast of San Francisco. Households, retail businesses, major food and beverage producers, light industries, manufacturers and vital military operations depend upon our service.
We safeguard public health and help protect environmentally sensitive Suisun Marsh, which is the nation’s largest brackish water marsh as well as the largest wetland on the Pacific Coast. This 116,000-acre region not only supports abundant plant life but also serves as a stopover for up to 1.5 million migratory birds traversing the Pacific Flyway each year. We are proud to play a part in the preservation of these marshlands.
An act of the California Legislature in 1951 created the Fairfield-Suisun Sewer District to perform wastewater collection and treatment, and water recycling services for all property within the boundaries of Fairfield, Suisun City and Travis Air Force Base. The District also operates a drainage maintenance utility that performs specified stormwater management services in conjunction with the cities. Establishment of the District has enabled well-coordinated management of our local wastewater and stormwater.
Our current treatment facilities, which in 1974 replaced two older plants, underwent major renovations and expansions in 1982, 1987, 1989, and 2010 to keep pace with population growth, economic expansion of our region and technological advancements.
Our treatment plant occupies about 150 acres. It draws from a collection system that consists of 12 pump stations and a 70-mile network of sewers that fan out throughout our service area. The sewer conduits range from 12 inches to 48 inches in diameter. The replacement cost for the system is estimated at $300 million—tangible evidence of the District’s significant investment in infrastructure.
The Fairfield and Suisun City stormwater drainage systems serve an area of 41 square miles. The drainage system encompasses seven pump stations to maintain flow of stormwater to the natural creek system and the marsh.
At the time the District was established, our service area had fewer than 6,000 residents. Today we serve a population more than 20 times that size. We’ve been able to accommodate the growth and evolving needs of our region by remaining flexible, dedicated to customer service and mindful of the trust placed in us to protect public health and the natural environment.
