Distribution lines receive gas from transmission pipelines at a juncture called the “district regulators,” where the pressure of gas in the lines is reduced as necessary for the local distribution system. While some large industrial and commercial customers do receive natural gas at transmission line pressure before it is reduced, lower-pressure distribution lines serve most customers.
Distribution lines bring natural gas from the city gate and regulator stations to service laterals and are usually located beneath public streets or alongside residential property lines. In rare cases, distribution lines are located in the rear of properties. Peoples distribution lines range from 3/4 inch to 48 inches in diameter; the pressure in these lines varies.
