Biosolids Program

Biosolids are nutrient rich organic and highly treated solid materials produced by the wastewater treatment process. This high-quality product can be recycled as a soil amendment on farm land or further processed as  a earth-like product for commercial and home gardens to improve and maintain fertile soil and stimulate plant growth.

The Orange County Sanitation District’s biosolids policy is to strive to recycle its biosolids using sustainable options while protecting public health and the environment.
