Lystek Case Study

Fairfield-Suisun Sewer District
Sustainable Biosolids Management Solution Case Study

Learn how the Fairfield-Suisun Sewer District (FSSD) in California entered into a unique P3 with Lystek to gain a sustainable biosolids management solution for the San Francisco Bay Area.

The 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.
Read the full case study to learn more about the challenges, benefits and results of this exciting and innovative project including: 
  • What challenges the District had to address from sensitive natural environment and tightening regulations to under-utilized assets/infrastructure to odors, pathogens, and potential run-off issues

  • How this unique P3 facilitated the construction and retrofit of a new state-of-the-art, 150,000 (U.S. ton) Organic Material Recovery Center (OMRC) which provided for a sustainable biosolids management solution for the San Francisco Bay Area

  • How Lystek's technology provided for the conversion of Class B biosolids material into a sale-able Class A EQ biofertilizer product.

  • How the District gained cost certainty in biosolids management for the next twenty (+) years
