The Bargersville Wastewater Treatment Plant Improvements project was selected for an Honor Award through the American Council of Engineering Companies of Indiana 2021 Engineering Excellence Awards competition.

In 2017, the discharge permit for the Town of Bargersville was revised to 1.0 mg/L total phosphorus limit and ongoing and anticipated future development in town was expected to increase flows beyond the treatment capacity of the plant. As a result, upgrades to both the capacity and treatment capabilities of the plant were need, including new anaerobic selector tanks to promote biological phosphorus removal (BPR), increased operational and treatment flexibility in the existing oxidation ditches through added sensors and submersible mixers, new secondary clarifiers to increase capacity and phosphorus removal, new return and waste-activated sludge pumps, a new belt filter press, and additional liquid sludge storage. These modifications will meet treatment needs for the next 20 years as well as provide operational flexibility to meet potential future nutrient limits.
