The Constantine Group provided engineering services to Charleston Water Systems in the form of design, permitting, and construction observation and administration for the upsizing of relocation of a 100-year old 6-inch water main along Calhoun Street on the peninsula of Charleston, SC from Elizabeth to Meeting Streets.  The project consisted of installation of approximately 900 linear feet of 12-inch ductile iron pipe that replaced the current water main, tie-ins, approximately 15 service connections, and all associated appurtenances.
