Successful Retrofit, Fairfield, CA

FSSDThe Fairfield-Suisun Sewer District (FSSD) serves more than 135,000 residential, commercial and industrial customers, overseeing wastewater management and sanitary sewers in California’s Solano County.

The FSSD’s existing water and wastewater treatment plant was constructed in the late 1970s and for those thirty years, FSSD had been sending their biosolids to landfill, to be used as daily cover. This historical practice came with clear drawbacks: Class B biosolids that still contained some pathogens, unpleasant odor, higher GHG emissions and the potential for “run-off” into local waterways.

The unique, Public-Private Partnership (P3) brought a new technology to the area as well as additional uses for this valuable material. Not only does this undertaking support the existing FSSD wastewater treatment facility to manage its biosolids, but it also converts what is sometimes considered “waste” into a range of fully recoverable resources with a variety of uses, including a higher quality effluent.

The forward-thinking leadership team at FSSD recognized that the lifespan of their landfill cover program was limited. As a result, the search for new and innovative uses for biosolids generated at the plant was amplified. It was during this search that conversations were initiated with Lystek, who, at the same time, were looking for innovative expansion opportunities in the U.S. market; in particular California.

After many positive conversations, it was agreed there were great synergies between the two organizations including the fact that the project would be able to make use of existing, under-utilized infrastructure such as a decommissioned lime stabilization building and system that has been inactive for over 20 years and surplus digester capacity at the FSSD plant.
