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.
• 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 and Reservoir Avenue will remain closed on weekdays between Frankfort Avenue and Mary T. Meagher Aquatic Center to allow the work to continue safely and smoothly. Reservoir Avenue will reopen at the close of business every Friday and stay open until Monday morning.  Due to increased construction activity, Reservoir Avenue at Frankfort Avenue will be closed Monday – Friday. To access Mary T. Aquatic Center, please use Brownsboro Road. Louisville Water would like to remind the public that there is no parking on Reservoir Avenue between Frankfort Avenue and Mary T. Aquatic Center.  It will be necessary to tow vehicles if the no parking ban is ignored. The Reservoir Relining Project has a dedicated project webpage.
