This improvements project is utilizing a progressive design-build approach to enhance the plant’s biosolids processing capabilities. Two new anaerobic digesters, each with a 1.4-million-gallon capacity, will significantly reduce waste volume, destroy volatile solids, and generate biogas for renewable energy use. The upgrade also includes primary sludge screening to remove debris and a new Dewatering and Drying Building equipped with centrifuges and a rotary drum thermal dryer to produce high-quality, odor-free pelletized biosolids. These enhancements will improve the efficiency, reliability, and sustainability of the W.B. Casey WRRF, positioning it to meet the county's needs for the next 40 years.
