Modernization of the existing South Dearborn Regional Sewer District Wastewater Treatment Plant will increase wastewater processing capacity for ongoing and future development of Dearborn County’s three river cities and the unincorporated county near the I-275 beltway exit, also known as Southeast Indiana’s gateway from the Cincinnati metro area. With planned new commercial and residential developments happening in the SDRSD WWTP service area, including St. Elizabeth Healthcare’s Cancer Center and Hospital, reliable wastewater treatment capacity is critical in this growing area.
The project includes improvements to the existing sludge treatment systems including the following: New anaerobic digester, digested sludge holding tank, sludge thickener, sludge presses, polymer injection systems, ultraviolet disinfection system, pumps, electrical supply systems, and accessories. Additionally, aged equipment will be replaced including aeration blowers, pumps, clarification units, electrical equipment, and ancillary equipment.
The Preliminary Engineering Report was completed in late 2020. Final design engineering began on May 1, 2021, and was completed in January of 2022. IDEM construction permits have been secured. Construction is scheduled to commence on or about September 1, 2022, with construction completion scheduled for May of 2023.
