Primary Digester No. 7 Project

USD Project Manager: Curtis Bosick
Contractor: C. Overaa & Co.
Awarded Contract Amount: $23,342,575
Estimated Completion Date: 12/2021

The Primary Digester No. 7 Project was one of the outcomes of the District’s Plant Solids System/ Capacity Assessment – Phase 1 that was completed in November 2016.  The assessment concluded that the plant’s anaerobic digestion process was at or nearing capacity and Primary Digester No. 6, the largest existing digester, could not reliably be taken out of service for cleaning and maintenance until additional digestion capacity is provided. The Primary Digester No. 7 Project will increase reliable digester capacity, improve efficiency, and provide flexibility for the future cleaning, rehabilitating, and replacing of existing digesters.
