Resource Recovery and Energy Efficiency Master Plan
Resource Recovery and Energy Efficiency Master Plan Client: City of St. Cloud, Minnesota Location: City of St. Cloud, Minnesota Donohue conducted an evaluation of resource recovery and energy efficiency opportunities at the St. Cloud Wastewater Treatment Facility (SCWWTF). The Resource Recovery and Energy Efficiency (R2E2) Master Plan Report developed sound energy practices, short- and long-term objectives, and implementation strategies related to energy efficiency and recovery. From a resource recovery perspective, the Plan developed a long-term biosolids strategy. The SCWWTF is designed to treat an average-day flow of 18 million gallons a day (mgd) with a peak flow capacity of 44 mgd. The facility has full biological nutrient removal through a modified Johannesburg process. Solids are an
