Metropolitan Wastewater Management Commission Capital Improvement Program INCREASE DIGESTION CAPACITY Description: Installation of a fourth digester for expanded production of Class B biosolids. This project also included supporting the plant-widelandscaping construction work that was completed in December of 2012. Status: As of January 9, 2017, the project to Increase Digestion Capacity is in the biddingphase for a fourth digester and construction should start in springof 2017. The MWMC has three existing digesters. Justification: Continue to meet the requirements for Class B digestion with the ability to take one digester out of service for cleaning and/or repairs. Project Driver: Addresses the need for anaerobic digestion capacity. The 2004 MWMC Facilities Plan considers an option to upgrade the existing digestion process to meet Class A biosolids standards as a strategy to secure a wider range of beneficial end-use options and increase program flexibility. Since that time, the MWMC has effectively expanded beneficial application of Class B biosolids with expansion of the Biocycle Poplar Farm, and through working with private sector end-users. Project Trigger: Estimates indicate that expanded digestion facilities will be needed by 2018.
