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 regulations. However, our history of innovation and record of staying in line or ahead of all drinking water standards is driving us to develop extra treatment standards 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 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 façade and stand approximately 60 feet tall.
• Construction is expected to start in June/July of 2025 and will take approximately 10-12 months to complete.

Redundant Pump Station

Louisville Water is also building a redundant pump station to improve the reliability of our water service. Once it’s built, we can update the existing pump station and piping system that provides water to most of Louisville.

• The pump station will be approximately 4,000 square feet and roughly 40 feet tall, which is several feet lower than the existing pump station.
• The exterior will be architecturally similar to the existing security building at our Stilz Avenue entrance, and designed to complement the architecture of the original pump station.
• Construction is expected to start in January.
• Overall construction will take approximately 2 years.

Smokestack Painting/Cellular Equipment

Louisville Water is painting the existing smokestack. Painting is expected to start in March of 2025.

• The existing tower has multiple cellular antennas attached to the smokestack that must be temporarily removed to allow for the painting. This will require the placement of two temporary cell towers. One will be located near the fountain and the second will be near our entrance off Stilz Avenue.
• The temporary towers will go up around the first of the year and will be in place for approximately six months. Once the smokestack painting is complete, the cellular antennas will be placed back onto the smokestack and the temporary cell towers will be removed.
