Biosolids Recycling
Reusing Solids from the Treatment Process
SacSewer has developed a diversified biosolids management program that is both environmentally friendly and of high value to ratepayers.
8,500 Dry Tons
of Biosolids Recycled Per Year
This two-pronged program consists of safely and effectively:
- Recycling biosolids into environmentally beneficial products
- Applying biosolids to land disposal units
Each year, SacSewer’s facility processes about 38,000 dry tons of biosolids, making the program one of the largest producers of biosolids in California. Approximately 75 percent of those biosolids are treated and then injected into on-site land disposal units, while roughly 25% or 8,500 dry tons are beneficially recycled at our Biosolids Recycling Facility (a partnership with Synagro).
Biosolids are rich in nitrogen and contain phosphorus, potassium, and micro-nutrients, all necessary to the growth process. As a fertilizer, biosolids retain soil moisture, helping to reduce soil erosion. As a soil enhancer, biosolids can be marketed as follows:
- Dry, pelletized, odorless fertilizer
- Green waste compost in which the biosolids are mixed with natural plant materials
- Garden-variety compost
SacSewer’s Biosolids Management Program includes conducting outreach to educate the public, farmers, and community leaders about the significant benefits of biosolids recycling.
