Blossom and Huger Sewer Improvements, City of Columbia, SC

Emergency-driven design following a sewer line collapse in the heart of downtown Columbia, leading to a long-term solution including 590 LF of 18-inch HOBAS centrifugally cast fiberglass reinforced polymer mortar (CCFRPM) pipe, 1,850 LF of 18-inch DIP, 2,336 LF of 12-inch DIP, and 31 manholes. Sewers were rerouted to remove access points from high traffic intersections, and three blocks of streetscape improvements to coincide with construction of the sewer.
