The Project

The City of West Lafayette is updating its combined sewer system to better protect the Wabash River from sewage pollution.
These changes will improve the Wastewater Treatment Plant’s ability to treat wastewater and help keep our environment healthy for future generations.

 


WHAT ARE CSOs?

A Combined Sewer Overflow (CSO) occurs when a sewer system that collects both water runoff and sanitary sewage, in the same pipe, overflows due to volume that exceeds capacity. This excess wastewater is discharged into the Wabash River.

HOW DO WE STOP OVERFLOWS?

To reduce the occurrence of CSOs, the city is installing a new interceptor sewer (a new pipe) to collect and direct more combined sewage to the Wastewater Treatment Plant for treatment prior to being discharged into the Wabash River.

WHY NOW?

Construction is being completed to ensure the city’s sewer system meets EPA requirements, and to not disturb any improvements made as part of the separate State Street Redevelopment Project.
