Service lines are the pipelines that transport gas to a customer’s gas meter or piping. The table is sorted by the number of miles of cast or wrought iron gas distribution main, but can be sorted by any of the columns. Charts show the change in main miles and service line counts over the years. Nationally, iron distribution main mileage has decreased by 16 percent from 2004 to 2011. The number of cast or wrought iron service lines has decreased by 66 percent over the same time period.
