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 the sediment in the north basin, which is the basin closest to the Mary T. Meagher Aquatic Center. We have removed the old liner and are preparing to install the new one. As we reline the north basin, we will also address the railing that surrounds it. Louisville Water remains committed to keeping the reservoir open to the public when the project is completed, so the railing must be improved. 

It 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 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. A new railing will allow us to reopen the reservoir 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 residuals 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.

In the coming weeks it will be necessary to close Reservoir Avenue near the tennis courts.  Before the closure, additional communication will be provided. This closure is only expected to last one day. Due to this project and the powder 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. This carbon is critical to our water treatment process and continuing to meet drinking water standards. The three silos are starting to take shape with concrete construction, which will house the silos.  When completed, these structures will be encased with brick.

For safety, we will keep the north sidewalk closed between Pennsylvania and Reservoir Avenues. 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. Construction of the silos is expected to last approximately 6-months.

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.
