Water Main Project to Provide Back-up Water Supply to Eastern Jefferson County

Friday October 18, 2013

Residents and drivers along Hurstbourne Lane have noticed a large line of pipes along the side of the roadway.  Louisville Water is in the midst of a large water main project that will provide a back-up system for the eastern part of Jefferson County.

Louisville Water is installing 3.1 miles of 36-inch diameter water main from the west side of I-265 near Wolf Pen Branch Road and ending at the corner of Westport and Hurstbourne Lane.  Currently, the crews are working along Hurstbourne Lane between Brownsboro and Westport Road. The project involves digging a trench along the project route, installing the pipe, backfilling the trench and restoring the ground.  When this project is completed, the transmission main will provide additional capacity along the proposed route as well as redundancy to the customers in the eastern part of Jefferson County.

It’s been an interesting project since some of the pipe has to cross under major highways (Interstate 71, Hurstbourne Lane/Brownsboro Road).  Large boring machines push the pipe under the highway in these cases while in most other areas, a 20-foot section of pipe is lowered into a trench one at a time.  During construction, we’ve worked to make sure one lane of traffic is always open.  The project is estimated at $6.5 million.  We began in February and should be finished in 2013.  As we move through the construction route, we are restoring the ground and sidewalks.

Louisville Water maintains over 4,100 miles of water main in its system.  Each year, the company’s capital budget includes replacing and repairing aging infrastructure and installing new systems to provide redundancy.
