Central Relief Drainage Project
Home Public Input Central Relief Drainage Project
MSD’s Central Relief Drain is a stormwater pipe that flows from the center of the city beginning south of Broadway and flows to the Ohio River. Currently, there are places along the pipe where a combination of wastewater and rainwater can enter the pipe and flow into the Ohio River. The Central Relief Drain Overflow Mitigation Project will reduce the frequency and volume of these combined sewer overflows.
The project will reduce the frequency and volume of overflows into this storm line. In one area, the work will route combined sewer flow into a portion of the combined sewer system that has more capacity and can handle the increased flow. We will also adjust diversion dam elevations to optimize flow through the combined sewer system.
Work at most of the 13 locations is expected to take 1-2 days per site to complete. There are three sites near Broadway that will take 3-5 days each to complete. Please see the map for work locations.

MSD will hold a Pardon Our Dust Meeting concerning the Central Relief Drain Overflow Mitigation project in the Old Louisville area (Magnolia Avenue). This meeting will provide an opportunity for community to learn more about the construction activities and schedule.
The Central Relief Drain Overflow Mitigation Project is a project that will reduce the frequency and volume of combined sewer overflows (CSOs) into MSD’s Central Relief Drain (a storm line that flows to the Ohio River). This is accomplished by rerouting CSOs to portions of the combined sewer system with greater capacity as well as adjusting combined sewer overflow dam elevations in order to optimize flow through the combined sewer system.
