Why Is It Important to Address the CSO Problem Now?

The City of Peru has been addressing its CSO problems for many years. Early projects included major stormwater separation projects on West Main Street, Oakdale, and Parkview Heights Subdivision. We also significantly increased the capacity of the wastewater treatment plant. In 2010, the city agreed to complete a Long Term Control Plan by 2030. The plan includes separation projects, manhole and sewer lining projects, and a storage facility to temporarily hold polluted stormwater until it can be treated at the wastewater treatment plant. This plan would eliminate combined sewer overflows up to a 10-year, one-hour rain event (1.88 inches of rain). Completing this project will help improve water quality in the Wabash River.
