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. The first phase of the project, which is under construction now and will wrap up mid-April, involves work on 2.2 miles of the water main, running from Eastern Parkway and Beargrass Creek near Poplar Level Road to Grinstead Drive near Lexington Road and Cherokee Park. The estimated cost of the entire project is $25 million.
