The 6.4 mile construction project along Eastern Parkway extends the life of one of Louisville Water Company’s oldest water mains. Installed between 1923 and 1930, this 48-inch cast iron transmission main carries water from the Crescent Hill Treatment Plant on Frankfort Avenue to downtown and the Cardinal Hill Reservoir in the south end of town. A transmission main is a critical piece of infrastructure used to transport an average of 15 million gallons of drinking water per day. This main ensures adequate pressure and supply for a significant portion of the city, including Crescent Hill, the Highlands, downtown, Old Louisville and South Louisville.
Renovating and repairing this large transmission main is a complex project because the pipe runs along a historic, heavily traveled parkway bordered by established neighborhoods, businesses and popular recreation areas. To minimize disruption, the project will be completed in phases over the course of three years. Phase 3 of the project involves work on the water main along Grinstead Drive, Lexington Road and Stilz Avenue. The estimated cost of the entire project is $25 million. Work on Phase 3 will be place between June 2019 - May 2020. Customers will not lose water due to this project.
