 Customer-Owned Underground Gas Lines: Some of the underground natural gas piping on personal property belongs to the property owner. Customer-owned pipeing is defined as any buried gas line that extend away from the gas meter. Typically, customer-owned gas piping is used to supply heat and hot water to another structure, like a detached garage, but it can also be used to heat swimming pools and for cooking on a gas grill.  If you have this type of gas line on your property, it is your responsiblity to initiate any inspection and necessary repair or replacement of customer-owned gas piping through a qualified professional, such as a licensed heating/cooling contractor or plumber.  Buried gas piping should be inspected periodically for leaks and for corrosion if the pipe is metal.  If a gas leak is detected, it may be necessary to interrupt your gas service temporarily until repairs are made.  Remember to contact Call Before You Dig (by dialing 811), a free service. It is important that you know the exact location of all buried utility lines before performing any excavation project. When excavating near buried gas piping, all excavations must be done by hand.

If you suspect a problem with any natural gas lines, call NPU's Gas Emergency line at 860-887-7207.
