Columbia Gas Aging Main Replacement Program (AMRP)

Various Locations

The Columbia Gas Aging Main Replacement Program (AMRP) was established to replace aging infrastructure across the utility’s entire service area. EMH&T has provided mapping and engineering services for approximately 1,700,000 linear feet, to date, of replacement gas main. In addition to design services, EMH&T’s Infratechnologies Division provided a full spectrum of infrastructure evaluation and management services to perform pre- and post-construction videotaping of sanitary and storm sewers and their associated laterals in areas where they could potentially impact the replacement of these aging gas lines.
