Document Description
Note: Review Per Lead The project consists of a new Digester No. 7, transfer tank, iron salts facility, replacement boiler, and various pipeline and utility improvements with USD's Alvarado WWTP. In 2016, results from a capacity assessment indicated that current volatile solids landings for anaerobic digestion are at original design capacity with all digesters in service. Additionally, it was determined that Digester No. 6, the largest existing digester cannot reliably be taken out of service for cleaning until additional digestion capacity is provided.
