Biosolids Management

What are biosolids?
The wastewater treatment process separates solids and water, after which clean and disinfected water is discharged to a neighboring water body, while the solids are carefully processed to meet state and federal regulations. This further processing converts the solids into a useful, cost effective fertilizer, which contains a range of plant-essential nutrients.

Water Environment Services operates four wastewater treatment plants, three of which produce biosolids for land application. WES currently applies biosolids to fields in Clackamas and Sherman Counties.
