OCSD's Biosolids Video
How does sewage sludge become biosolids? Are biosolids safe? How do biosolids help mitigate climate change?

Over the course of 2013, we recycled almost all of our biosolids which was made possible by our exceptional source control, operations, and biosolids management programs, which are all part of our biosolids management system. In 2013, the pollutant concentrations in our biosolids were below well below the regulatory limits. OCSD continues to improve the productivity of farmland by using the soil conditioning properties and nutrient content found in biosolids.
