Title: Evansville East Wastewater Treatment Plant: Capacity Expansion Project
Description: The City of Evansville owns and operates its East Wastewater Treatment Plant, which treats a fraction of the City’s wastewater and combined storm sewers by providing screening and grit removal, primary treatment, secondary treatment using activated sludge, and disinfection. The City signed a Consent Decree with IDEM, USEPA, and the US Department of Justice to comply with the requirements of the Clean Water Act by reducing sewage overflows and implementing upgrades to the plant. For the East WWTP that meant providing full secondary treatment for flows up to 40 MGD. The primary objectives of this project were to upgrade the plant to meet the requirements of the Consent Decree as well as ancillary improvements that have been identified.
