UK Trunk Sewer C, D, and E
FAYETTE COUNTY, KY
WATER RESOURCES
As part of the LFUCG Division of Water Quality (DWQ) Consent Decree, Palmer Engineering and its sub-consultants were selected to design UK Trunk Sewers C, D, and E, outlined in the Remedial Measures Plan. This critical project is located in a dense urban area of Lexington, running through portions of the University of Kentucky campus and several major city streets.
The sewer alignment begins at Chair Avenue and extends to High Street, with the majority of construction occurring in the right-of-way along Chair Avenue, Oliver Lewis Way, Bolivar Street, S. Upper Street, Avenue of Champions, Rose Street, and Euclid Avenue. A section will also pass through a sanitary easement on the UK campus near Winslow Street.

Challenges
High-Traffic Urban Location: The project was situated in one of the busiest areas of Lexington, making it one of the most complex line-work efforts in the Remedial Measures Plan.
Minimizing Traffic Impacts: Construction options had to account for heavy daily traffic volumes, limited work windows, and the need to maintain mobility and safety.
Evaluating Multiple Construction Methods: The design team analyzed several technically challenging alternatives, including traditional dig-and-replace gravity sewer, micro-tunneling, and a new pump station with force main.
Balancing Cost and Constructability: Palmer was tasked with assessing each option’s feasibility, estimating costs, and examining traffic impacts to support informed decision-making.
