How is natural gas transported throughout CT?

LDC mains generally run down public streets and are typically 2” through 20” in diameter. Lines from the streets to homes and businesses are usually between ½” and 4”. While most distribution lines operate at ¼ pounds per square inch gauge (psig) (low pressure) through 100 psig, there are some special very high pressure distribution lines that operate at pressures as high as 750 psig. There are approximately 8,400 miles of distribution mains and approximately 475,000 services in Connecticut.
