Ever seen these road markings? If you start looking you'll see them everywhere on our streets. Here's what it means: A natural gas pipeline is in-line with the axis of the double arrow (about 5 feet belowground). In this case, the pipe is 8" diameter cast iron (CI). These markings come from the utility in response to dig safe requests, when someone needs to dig and wants to avoid hitting a pipeline.So if the utility can mark our streets, shouldn't we be able to mark where the leaks are too?
