Renew Evansville

The Evansville Water and Sewer Utility has been developing what will be the largest capital improvement project in Evansville’s history. This program – Renew Evansville – is a state and federal mandate that will significantly upgrade one of Evansville’s most important, yet unseen, assets . . . its sewer system.

Renew Evansville is the Evansville Water and Sewer Utility’s approximately 20-year plan to improve our city’s sewer system and ensure compliance with the Clean Water Act of 1972. This major capital campaign will include:

  • Dramatic upgrades to existing infrastructure
  • The construction of new infrastructure
  • Sustainable and “green” infrastructure solutions
  • Improvements to the utility’s operations and maintenance

Engineers and Utility management have developed a long-term Integrated Overflow Control Plan (IOCP) that addresses Evansville’s combined sewer overflows and capacity issues in portions of the separate sanitary sewer system. The result will be a significant reduction in combined sewer overflows into the Ohio River and Pigeon Creek during rain events and snowmelt, and a reduction of backups and sewer overflows in the separate sanitary sewer system.

The initial draft of the IOCP was presented to the public and state and federal regulators for comment in late summer 2012. A final version of the plan was originally scheduled to be delivered to regulators on November 30, 2012. The Indiana Department of Environmental Management and the U.S. Environmental Protection Agency (EPA) agreed to extend the deadline for final plan submission until May 31, 2013. The extension was granted after considering the unprecedented rainfall Evansville received in 2011, which negatively impacted the Utility’s ability to finalize a sewer system computer model. The historic rainfalls during this time increased the complexities and potential costs associated with creating a long-term plan to capture millions of gallons of additional combined sewer overflows. Upon plan approval, the Evansville Water and Sewer Utility is expected to have up to 20 years or more, depending on economic conditions, to construct or implement all of the changes outlined in the IOCP.
