In accordance with their Consent Decree, LFUCG Division of Water Quality (DWQ) is required to construct UK Trunk Sewers C, D, and E as outlined in the Remedial Measures Plan. Palmer Engineering, and their sub-consultants, were selected by DWQ to design these trunk sewers. The project is located in a very urban portion of Lexington, part of which is in the heart the University of Kentucky campus. The project is proposed to begin on Chair Avenue and extend all the way to High Street. A majority of the sewer will be located in the street right-of-way of Chair Avenue, Oliver Lewis Way, Bolivar Street, S. Upper Street, Avenue of Champions, Rose Street, and Euclid Avenue. The only exception to this being a portion of the sewer to be constructed within sanitary easement on the University of Kentucky’s campus along Winslow St.

The project is thought to be one of the more difficult line-work projects in the Remedial Measures Plan because of the impacts it will have on traffic during construction. Due to the anticipated traffic implications, several options were evaluated by the design team to balance construction costs versus impacts. These options included a traditional dig and replace gravity sewer approach; a micro-tunneling approach; and the installation of a new pump station and force main. Palmer Engineering provided preliminary cost estimates for the various alternatives as well as preliminary analysis of estimated size and duration of street closures. Ultimately, DWQ selected the traditional dig and replace option.

The UK Trunk C, D, & E project consist of approximately 205 linear feet of 8-inch sanitary pipe, 71 linear feet 10-inch sanitary pipe, 94 linear feet of 12-inch sanitary pipe, 25 linear feet of 15-inch sanitary pipe, 80 linear feet of 18-inch sanitary pipe, 4,208 linear feet of 21-inch sanitary pipe, 1,822 linear feet of 24-inch sanitary pipe, 1,898 linear feet of 27-inch sanitary pipe, 595 linear feet of 30-inch sanitary pipe, and 67 manholes ranging between 4 and 6 feet in diameter. Final design is complete and the project was advertised for bid on September 26, 2019.
