WWTP Upgrades

The Project consists of the following upgrades at the City's Wastewater Treatment Plant located at 410 Defiance Rd., St. Marys, Ohio: 1. Demolition of the previously abandoned Aeration and Final Settling Tanks, Blower Building, and Chlorination Building and Tank and of the existing 45 ft. diameter Sludge Holding Tank; to make room for the addition of a new Sludge Dewatering Building and Dewatered Sludge Storage Facility. 2. New Sludge Dewatering Building will house new multi-drum volute style sludge dewatering press and supporting polymer feed and dewatered sludge conveyance equipment to transfer dewatered sludge from the press to the Dewatered Sludge Storage Facility. Additional conveyance equipment will be located within the Dewatered Sludge Storage Facility for distributing the dewatered sludge. 3. Removal of existing equipment and piping from the existing Sludge Control Building and 55 ft. diameter sludge storage tank to allow for new piping and equipment to be installed including: a sludge grinder and sludge press feed pumps, new sludge inlet, outlet, and supernatant piping to/from the existing Sludge Storage Tank, and a large bubble mixing system for the tank. 4. Upgrades to the existing Ultraviolet Disinfection Facility and existing Plant Pumping Station including replacement of existing equipment, structural modifications needed to accommodate new equipment and structural repairs.
