Lexington Fayette Urban County Government (LFUCG) selected Palmer Engineering to evaluate alternatives and design the replacement of approximately 2,450 linear feet of sanitary sewer. The existing gravity sewer consists of vitrified clay pipe in 10-inch and 12-inch sizes; the system is in poor condition and under capacity.
Discussions with the US Army Corps of Engineers and the KY Division of water were held to evaluate each alternative; public perception was also considered in the recommendation of the selected alternative. Preliminary cost estimates were also reviewed to determine the most cost-effective option.
The selected design minimized the number of stream crossings and impacts to residents’ property. The new 12-inch gravity sewer was constructed to increase capacity and eliminate infiltration into the sewer system.
