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.
