Constantine provided engineering services to Charleston Water System in the form of design, permitting, and construction observation and administration for the upsizing and relocation of a 100-year old 6-inch water main along Huger and Nassau Streets as well as a new water main on Stuart and America Streets on the peninsula of Charleston, SC. The project consisted of installation of approximately 2,100 linear feet of 8 and 12-inch ductile iron pipe that replaced the existing water main, tie-ins, approximately ten service connections, and all associated appurtenances.
