The city of Maryville Water and Sewer Department has been awarded a 2022 Governor’s Environmental Stewardship Award for Water Quality. Tennessee Gov. Bill Lee and Department of Environment and Conservation (TDEC) Commissioner David Salyers will formally present the awards at a ceremony scheduled for July 25 in Franklin. The Maryville Regional Wastewater Treatment Plant (MRWWTP) serves more than 22,000 customers in the cities of Maryville and Alcoa as well as the Knox Chapman Utility District. To better serve customers, the facility underwent a major expansion and renovations that included biological nutrient removal, utilizing anaerobic and anoxic zones in combination with oxidation ditches, the Autothermal Thermophilic Aerobic Digestion (ATAD), and the launch of a composting facility. The city has saved more than $200,000 annually in tipping fees, not including associated hauling costs, as a result. Maryville is one of only 11 facilities in the state with the Exceptional Quality status on their biosolids permit.
