The Waterway Protection Tunnel will capture 22 combined sewer overflow points that now discharge 351 million gallons of mixtures of sewage and rainwater in a typical rainfall year that flow into the South Fork of Beargrass Creek and the Ohio River.
The tunnel will allow capture of 98 percent of these overflows and store the mixtures until the rain subsides and sewer system capacity is available. The mixture will then be pumped back into the sewer system and conveyed to our Morris Forman Water Quality Treatment Center resulting in a safer, cleaner environment and waterways for our community.

MSD’s Waterway Protection Tunnel is an innovative solution that replaces three storage basins originally planned to be located near Lexington Road and Payne Street; Story Avenue and Main Street; and 13th and Rowan streets. Now, advances in technology and reductions in the cost to build the tunnel make it feasible to use a tunnel instead of three basins.
The tunnel will have more storage capacity than the three basins for approximately the same cost, but construction will be less disruptive to Louisville’s Main Street arts and business district, Butchertown’s business district, Irish Hills’ residential community, and area traffic during the two-year construction period.
In addition, construction on the tunnel project will create about 200 jobs.
Land provided for Waterfront Park expansion
When the Waterway Protection Tunnel is complete, the construction staging area at 12th and Rowan streets will be turned over to the Waterfront Development Corporation to be developed into an expansion for Waterfront Park.
Plans call for a public greenspace for the community to enjoy, including pathways, footbridges, play areas, fountains and sculptures. MSD worked closely with Waterfront Development on the design of the pump station so that it compliments the planned park expansion.
