Rehabilitation of the existing 108-inch corrugated metal pipe (CMP) storm drain system for Hunley Park at Joint Base Charleston Air Base in Charleston, South Carolina. Ruby-Collins Trenchless team installed 100 linear feet of Sekisui spiral wound PVC lining system, creating a new 100-inch diameter pipe inside the failing existing corrugated metal pipe to substantially extend the service life of this aging storm sewer infrastructure. The project was completed on time and on budget, demonstrating efficient execution within the constraints of an active military installation.
