What are Biosolids?

We’ve innovated ways to recycle a byproduct of the wastewater treatment process to create “biosolids” as a natural and environmentally-sound fertilizer for local farmers in Anderson, Greenville, Laurens, and Spartanburg counties. 

Over the past three years, we’ve applied biosolids to more than 12,000 acres in these counties. In 2020, more than 6,390 dry tons of ReWa biosolids nourished local fields and pastures to keep them healthy and thriving.

Award-Winning Innovation

Our biosolids program has grown tremendously since its inception in 1989 at our Durbin Creek Water Resource Recovery Facility (WRRF) and received numerous awards over the years:

  • National Second Place Award for beneficial use of biosolids, large operating projects by the Environmental Protection Agency (1998).
  • Beneficial Use of Biosolids Award by the Environmental Protection Agency (2000).
  • Utility of the Future by the National Association of Clean Water Agencies (2017).
  • Biosolids Program of the Year by Water Environment Association of South Carolina (2019).
