Beneficial Reuse

The District beneficially reuses all the wastewater residuals generated in the treatment process. Wastewater “biosolids” are used to fertilize alfalfa hay crops and for turf grass production. In addition, biosolids are mixed with ground wood waste and composted until a quality soil amendment is produced. This soil amendment is then sold to the general public.
