Louisville Water has multiple projects underway at the Crescent Hill Water Treatment Plant property. Below is a description of each project and a construction update. You can find more information at LouisvilleWater.com by clicking here.

Reservoir Relining Project

We’ve finished the first year of a multi-year project to reline the Crescent Hill Reservoir. The first milestone has been reached: the contractor has removed most of the sediment in the north basin, which is the basin closest to the Mary T. Meagher Aquatic Center. Now, we’re ready to remove the old liner and install the new one. Once we finish on the north basin, we’ll move to the south basin that is near Frankfort Avenue.

As we reline the north basin, we’re also addressing the railing that surrounds the basin. In the coming weeks, we will remove the railing surrounding this basin. This should take three months. Louisville Water remains committed to keeping the reservoir open to the public when the project is completed, and the railing must be improved.  The railing is in poor condition and does not meet today’s safety standards.  After working for more than a year on options to restore the existing railing, we determined the cost to rehab the mile-and-a-half of the existing railing was nearly four times the cost of replacing it with a similar railing. We will restore sections of the original railing for display at the reservoir and other Louisville Water facilities, such as the WaterWorks Museum. The new railing allows us to keep the reservoir open to the public.

Once the north basin is completed, we will duplicate the process for the south.  We hope to complete the project in 2029 and then reopen the reservoir to the public.

Residual Line Project at Crescent Hill

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 along Zorn Avenue and River Road. Our contractor is currently working between the railroad tracks and Reservoir Avenue. Due to this project and the power activated carbon system project, access to the green space remains limited.  

Crescent Hill Powder Activated Carbon (PAC) System

We are building new silos near Frankfort Avenue and Reservoir Avenue that will allow us to store larger amounts of powder activated carbon. The carbon is critical to our water treatment process and continuing to meet drinking water standards.

Reservoir Avenue at Frankfort Avenue will close for one week starting August 28 so that we can install new pipe across Reservoir Avenue. This closure coincides with Mary T. Meagher Aquatic Center closure. Except for this road closure on August 29 and 30th, Reservoir Avenue will reopen for traffic on weekends to accommodate access to the Aquatic Center.

Constructing the silos should last another 12 months and for safety, we will keep the north sidewalk closed between Pennsylvania and Reservoir Avenues. To safely access the site, it was necessary to construct a temporary access road between Pennsylvania Avenue and the construction site.  Residents should expect normal construction activity and noise during the project. Once we complete the work, we will remove the access road and restore and reopen the sidewalk.

Preserving Our History – Did You Know?

• It took 2 years, 8 months, and 4 days to build the reservoir. The groundbreaking was April 11, 1877, but it did not start operations until December 15, 1879.
