WEST LAFAYETTE, Ind. (November 23, 2022) – The closure of North River Road and its intersection with Happy Hollow Road has been extended through Spring 2023 due to poor ground conditions and third-party utility delays. 

This construction is part of River Road CSO, the City of West Lafayette’s ongoing effort to improve its stormwater and wastewater collection system and prevent future pollution of the Wabash River. 

Currently, West Lafayette’s sewer system transports stormwater and wastewater through one system to the wastewater treatment plant. During normal rain events with 1⁄4-inch of rainfall or more, the combined system capacity can become overwhelmed, resulting in stormwater and wastewater overflowing into the Wabash River. This is referred to as a combined sewer overflow, or CSO. 

In an effort to reduce CSO events and improve the health of the Wabash River, the City of West Lafayette began the first phase of River Road CSO in 2016. Since that phase’s completion, the area has seen a reduction from 150 overflows in a five-year period to less than five since 2017. After the current phase is completed, the area impacted by closures will see a similar reduction in CSO events.

In all, River Road CSO will help the City of West Lafayette protect the Wabash while meeting standards set by the United States Environmental Protection Agency and Indiana Department of Environmental Management.
