The Fort Hunt Road Service Road sewer services 21 homes and was constructed as an 8-inch diameter clay pipe. The Wastewater Collection Division inspected the pipe and identified a break that appeared to have been caused by a utility cross bore from a utility pole which was visible on the pipe inspection video. The Wastewater Design and Construction Division kicked off an expedited design and construction project to address this damaged sewer pipe. The project included the installation of roughly 350-feet of 8-inch diameter gravity sewer, 4 new manholes, 2 sewer reconnections, and abandonment-in-place of roughly 350-feet of old 8-inch diameter clay pipe. This project was substantially complete on June 4, 2021.
