Crescent Hill Water Treatment Plant Infrastructure Upgrades

Crescent Hill Carbon Storage Silos

The Environmental Protection Agency has set new regulatory standards for the treatment of PFAS. PFAS or per-and polyfluoroalkyl substances are a group of manufactured chemicals that do not naturally occur.

Louisville Water is currently in compliance with the proposed PFAS regulations. However, our history of innovation and record of staying in line or ahead of all drinking water standards is driving us to develop advanced treatment for removing PFAS. Our strategy is to treat PFAS with powder activated carbon (PAC). PAC is effective at removing the PFAS we see in our source water. PAC is also effective in removing other compounds that greatly improve the quality of our finished drinking water. To implement this strategy, it is necessary to build additional storage capacity and upgrade the existing PAC feed system.

• Three storage silos and a small building will be built within our existing fence line, parallel to the railroad tracks along Frankfort Avenue between Pennsylvania and Reservoir avenues.
• The silos will feature a brick facade and stand approximately 60 feet tall.
• To safely access the site, it is necessary to build a temporary access road between Pennsylvania Avenue and the construction site. Residents should expect normal construction activity and noise during the project. It will also be necessary to close the sidewalk between Pennsylvania and Reservoir Avenues. Following the project’s completion, we will remove the access road and restore the sidewalk.
• Construction is expected to start in February of 2026 and will take approximately 18 months to complete.

Residual Line Project

Louisville Water is constructing a new residual line to remove treatment residual from the plant. This line will connect with the recently constructed residual line we installed in Zorn Avenue and River Road. Currently, our contractor is working on our property that is adjacent to the fountain on Frankfort Avenue. Beginning in early March 2026, we will bore under Frankfort Avenue. This work will not impact traffic on Frankfort Avenue. After boring under the road, the line will run behind our basins parallel to Pennsylvania Avenue. We are currently installing temporary fencing in this area. This will restrict access to the green space from Pennsylvania Avenue and portions of Reservoir Avenue. The project is expected to last approximately 12 months. When completed the temporary fencing will be removed and the area will be restored. For more information about the River Road segment of the project, click here.

Reservoir Relining Project

Our project to reline the reservoir is progressing. The walkway around the reservoir is closed. For construction safety and to accomodate guests to the Marty T. Meagher Aquatic Center, we’re using two traffic patterns.

1. Monday – Friday: Reservoir Avenue remains closed on weekdays between Frankfort Avenue and the Aquatic Center. Please use Brownsboro Road to access the Mary T. Meagher Aquatic Center. There is no parking on Reservoir Avenue between Frankfort Avenue and the Aquatic Center. We will tow vehicles that ignore the no-parking ban. The sidewalks in this area of Reservoir Avenue are also closed.
2. Reservoir Avenue fully opens to traffic at the close of business every Friday through Monday morning. This opening accommodates weekend activity at the Aquatic Center. The no-parking ban is not in effect but the sidewalks remain closed.
