Eastern Parkway Water Transmission Main Rehabilitation-Sliplining Renews Critical 48-Inch Cast Iron Main along Historic Olmstead Parkway in Louisville, Kentucky
This project 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. It transports 15 to 20 million gallons of drinking water daily to Crescent Hill, the Highlands, downtown, Old Louisville, and South Louisville. The pipe runs along historic Olmstead Parkway, a major east/west arterial with an average traffic volume of 20,000 vehicles per day, bordered by established neighborhoods, businesses, and popular recreation areas. Being the largest water main repair project in Louisville Water's 156-year history along a heavily traveled historic parkway, the project presented many challenges. A partnership by the owner, consultant, stakeholders, contractor, and pipe manufacturer set the foundation for successful design and construction for Phase I, renewal of more than 11,000 feet of pipe during a restricted off-peak winter demand period, and providing continued service to all existing customers. This paper discusses aspects of the preliminary engineering evaluation, stakeholder involvement and communications, final design solutions, and effective construction modifications that resulted in a successful project that exceeded expectations.
