Biosolids 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 biosolids available free of charge to the public. The availability of free Class A biosolids are subject to various environmental factors. Please call us in advance to confirm if and when biosolids are available.

*Note you will need to bring your own container to transport our biosolids.
