certified biosolids program sewage sludge certification

What are Biosolids?  

Biosolids (a.k.a. treated sewage sludge) are nutrient-rich, treated organic matter recovered through the treatment of wastewater. Find more information in our Biosolids Fact Sheet and Annual Performance brochure.

 

How are Biosolids Used?

This high-quality product can be recycled as a soil amendment for farm land or composted to an earth-like soil amendment for agriculture, nurseries, or home gardens. Because biosolids are nutrient-rich, contain beneficial microbes, retain water, and build soil structure, biosolids are a low-cost and environmentally-friendly alternative to popular petroleum-based fertilizers. Find more information in our Biosolids Fact Sheet and Annual Performance brochure.

What is a Certified Biosolids Program?

OCSD is celebrating 10 years of a having our biosolids program certified by the National Biosoilds Partnership (NBP). The NBP's nationwide certification is based on the ISO 14001 and customized for biosolids with the goal of continuously improving outcomes related to relationships with interested parties, enviornmental performance, regulatory compliance, and quality management practices.

Certification involves a rigorous process of external review and continued program improvement.

This certification is another way we ensure the biosolids program is sustainable for years to come. Read more on our Certified Biosolids Program page.
