Frankfort Avenue Main Replacement Project

Frankfort Avenue Main Replacement Project

Historic Water Main Improvement

In August 2021, Louisville Water Company will begin a one-year project near the Crescent Hill Water Treatment Plant to replace one of its oldest water mains and install additional pipes to deliver more drinking water. The Frankfort Avenue Main Replacement Project will increase the size and reliability of critical water mains near the treatment plant. This $13.2 million investment includes work on Frankfort, Stilz, and Reservoir Avenues.

This is a complex project in a busy, vibrant neighborhood. Detours and road closings, though inconvenient, are all part of installing large water mains in high-traffic areas. Residents and business owners will routinely be kept up to date as the work progresses.

Project Overview

Louisville Water’s Frankfort Avenue Main Replacement Project includes two phases:

Phase I begins in August with the installation of a 60-inch diameter main in the middle of Frankfort Avenue. A 36-inch diameter main will be removed. This pipe was installed in 1877, the same year that Rutherford B. Hays was president and Thomas Edison introduced the phonograph. Construction will move west to east from Crescent Court to Reservoir Avenue. Work continues later in the fall, with the installation of a 60-inch diameter main on Stilz Avenue from Grinstead Drive to Frankfort Avenue.

Phase II, slated to begin in early 2022, will involve the installation of a new 42-inch diameter main at Frankfort and Reservoir Avenues.

Project Detour

A History of Innovation

Nearly a century and a half ago, installation of a new 36-inch diameter main, was part of a larger project that included plans to build the Crescent Hill Reservoir. The growing city needed better water pressure and fire protection.

With the installation of the water main in 1879 and the completion of the reservoir, Louisville Water became one of the first and largest businesses in the Crescent Hill area. It would be many more years before the neighborhood blossomed into the he beautiful, lively area we know today.

Why is the Construction Necessary?

The Frankfort Avenue Main Replacement Project is a critical part of Louisville Water’s distribution network. The 1877 main has lived a good life, delivering water for 144 years. New, larger mains will provide additional supply lines and more flexibility to move and reroute water to customers when and where it’s needed. The Crescent Hill Water Treatment Plant is the largest water treatment plant in Kentucky and produces most of the drinking water for Louisville Water customers (The B.E. Payne Water Treatment plant is the company’s other facility.) Infrastructure investments like these, in and around Frankfort Avenue, ensure the continued delivery of safe, reliable, high-quality water to nearly one million people every day.

Community Involvement

Community engagement is important. This is a large project and the immediate neighbors and those who travel along Frankfort Avenue will be kept up-to-date through mailings, social media, emails, media briefings, and virtual/face-to-face meetings.
