CGA programs include the 811 national telephone system, which refers callers to the appropriate local office for information on existing underground services in specific areas and the “Call Before You Dig” program. This one-call system handles nearly 28 million utility location requests per year, with a goal of avoiding incidents such as accidental digging into gas, sewer or water lines. Additional services include a centralized repository of best practices information and one-stop damage reporting systems and software. CGA consists of 1,700 government and private entities that provide information on underground services, trenching and trenchless construction best practices and safety information.
