Improvements at Crescent Hill Filtration Plant

Louisville Water is in the midst of a $100 million complete renovation at the Crescent Hill Filtration Plant. This facility, which opened in 1909, handles about 70% of Louisville Water’s daily production.

To date, most of the work has been in a fenced area behind the plant and has included the construction of an elevated storage tank, a chlorine-generation facility that eliminated a community risk for rail cars to transport chlorine, rebuilding the east filtration gallery and the softening basins.

The next stage of construction is on Reservoir Avenue. We are rehabilitating the coagulation basins that sit directly across the Crescent Hill Reservoir. The scope includes concrete work and new lighting. We’ll also renovate the building that sits between the basins with masonry work, painting, roof repairs and new windows.

These improvements will improve efficiencies at the facility and will help Louisville Water stay ahead of the nation’s strict drinking water standards. One of those standards, the Long Term 2 Surface Water Treatment Rule (LT2) takes effect in 2012. The new filtration system we are installing will help us exceed this goal that deals with disease-causing microorganisms and Cryptosporidium that can appear in drinking water.

While Louisville Water began efforts in 2006 to comply with the upcoming rule, all of the necessary improvements at the Crescent Hill Plant will not be complete in 2012. The Kentucky Division of Water has granted Louisville Water’s request for a 12-month extension for compliance with LT2 at the Crescent Hill Plant. Louisville Water consistently meets the new LT2 rule. Once the improvements are complete, we will have an additional treatment barrier to further ensure compliance. Over the next year, Louisville Water will continue to monitor and report water quality data to the Kentucky Division of Water. All other requirements for the Surface Water Treatment Rules will remain in effect.
