The Facility is undergoing upgrades that include thermal dryers, tertiary filters, upgrades to primary treatment, digestions, gas, UV, and the Outfall, in addition to sidestream treatment. All upgrades are expected to be completed and operational at the end of year 2029. The Facility has a permitted biosolids program and an approved pretreatment program.
