A Letter to the Downtown Community From MSD:
Major sewer pipe on Main Street requires repair and closure of the south side parking lane and about four-feet of sidewalk between Fourth and Seventh streets.
The south side parking lane on Main Street in front of the PNC Tower has been closed to traffic since March 2, 2018. I want you to understand the reason behind the decision to not only keep that area closed but to expand the closure to Seventh Street. We realize these closures are disruptive, and do not make this decision lightly, as this area is the heart of our city’s business, entertainment and tourism districts. However, public safety clearly must be our top priority.
The damaged 84-inch diameter sewer pipe, which is about 60 years old, carries approximately 40 percent of the wastewater flow generated in Louisville Metro. This pipe runs under the south side parking lane on Main Street, between Fourth and Seventh streets. Expert inspectors are concerned that corrosion caused by sewer gases in the pipe could cause a cave-in in that area.
MSD commissioned an inspection of this pipe — called the Ohio River Interceptor — in November 2017 and used technology that allows engineers to analyze the pipe without having to empty it. The resulting March 1, 2018, report revealed that some of the concrete and rebar pipe was wearing away, especially in the section of the sewer main between Fourth and Fifth streets. We then asked two additional outside engineering firms, with experts in large sewer pipe rehabilitation, to independently review the inspection report. Both expert firms confirmed the damage and potential risks of the pipe and expanded the area of urgency to include Fourth to Seventh streets.
We are now working with consultants on repair options and timelines, while also working closely with other utilities and Louisville Metro to evaluate any other risks and ensure public safety.
Until the repairs are complete, MSD will close the south side parking lane and about four-feet of sidewalk between Fourth and Seventh streets and is monitoring the area on a daily basis for any signs of collapse. The closures reflect safety concerns by both MSD and Louisville Metro government.
We will keep you informed as plans develop. You may visit our website at LouisvilleMSD.org/WestMainRepair for developing information.
The Ohio River Interceptor is one of the hundreds of projects identified in MSD’s Critical Repair & Reinvestment Plan. The Plan includes funding to rehabilitate major sewer lines within the service area, including this interceptor.
