Biosolids

Biosolids are the treated, solid residuals that remain after the treatment of wastewater. Biosolids are rich in nutrients and are used as a soil fertilizer. Biosolids land application sites are typically rural, agricultural properties that are permitted through the Colorado Department of Public Health (CDPHE) Water Quality Control Division for the land application of biosolids.
