The Kentucky Science Center’s Engineering Days on February 8 offered students an opportunity to speak one-on-one with engineering professionals who imagine, design and create the world around us. MSD’s Waterway Protection Tunnel Project Manager Jacob Mathis spoke with students from across the region about MSD’s largest project in our history.

MSD is holding a series of open house meetings to discuss changes to existing floodplain maps by the Federal Emergency Management Agency (FEMA), which may affect your property’s floodplain status. Changes to the maps may affect your property’s flood status

MSD continues to work as diligently and safely as possible to repair a large, 84-inch diameter sewer line that is more than 20-feet below Main Street. It is an emergency repair since this pipe carries 40 percent of the community’s wastewater to MSD’s Morris Forman Water Quality Treatment Center for proper treatment and release to the Ohio River.

Excavated rock from MSD’s Clifton Heights Combined Sewer Overflow (CSO) Basin became part of the base for a parking lot that helped remedy a parking problem at the Robley Rex Veterans Administration Medical Center on Zorn Avenue.

Louisville MSD and Louisville Water Company took the opportunity on Friday, Nov. 9, to honor their employees who have given and continue to give to their country through service in the armed forces.

The legacy of Louisville’s own Muhammad Ali continues to live on as the name “Bumblebee” was unveiled for the MSD tunnel boring machine, which will excavate MSD’s Waterway Protection Tunnel underneath Louisville.

A trip to Mt. Pleasant, Pennsylvania, about an hour southeast of Pittsburgh, gave MSD Engineer and Project Manager Jacob Mathis, P.E. and Engineering-Collections System and Construction Manager Greg Powell, P.E. an opportunity to see the tunnel boring machine that will create the Waterway Protection Tunnel. Mt. Pleasant is where tunnel contractor J.F. Shea Co., Inc. operates a facility to rebuild and test tunnel boring machines prior to shipping to a project site.

MSD held a Public Outreach Meeting August 28th to share an update on the 1.5 mile extension of the Waterway Protection Tunnel and the elimination of the I-64 & Grinstead CSO Basin. Area residents were given the opportunity to ask questions about the extension and the project in general.

A recently discovered sewer cave-in has forced Louisville MSD to reduce traffic on Main Street in the midst of other repairs to the same sewer line underneath the street.

The cave-in was found when video from a remote-control camera placed into the line for inspection revealed a hole in the side of the pipe. Debris, including abandoned pipes, have fallen into the large sewer line from this hole. 

The cave-in wasn’t present when MSD last inspected this portion of the pipe on June 21.

MSD contractors working to build a massive underground tunnel to prevent wastewater and stormwater from overflowing and entering the Ohio River and Beargrass Creek have reached a significant milestone. The “working” and pump station shafts — which will carry workers and equipment underground — have reached their full depth of 220 feet below the surface.
