Bio-Solids are nutrient-rich organic materials removed from the wastewater treatment process and are treated so they can be applied as fertilizer or soil amendment.

Our District makes bio-solids available free of charge to the public. The availability of free Class A bio-solids are subject to various environmental factors. Please call us in advance to confirm if and when bio-solids are available.

*Note you will need to bring your own container to transport our bio-solids.

For more information on bio-solids uses and safety, please visit the EPA’s website at www.epa.gov/biosolids/frequent-questions-about-biosolids.

Limited quantities of Class A biosolids are available on a first-come-first-served basis. For more information please call 805-967-4519
