The Sioux Falls Water Reclamation Facility (WRF) treats primary and secondary sludges in three primary anaerobic digesters and one secondary digester. Treated sludge is stored in lagoons until disposal by land application. Continuation of the land application process will require significant investment. The primary purpose of this study is to evaluate alternative biosolids handling and disposal methods. The study includes a forecast of biosolids production rates due to growth and future nutrient removal treatment processes. The study also addresses processing and storage options, and establishes a 20-year biosolids management plan.
