The term “private utility lines” refers to the portion of an underground utility that is generally located on private property between the meter and the building. In the case of water service lines, the meter is often located underground in a “meter box” at the property line. The water pipe from the meter box to the house is owned by the homeowner. The homeowner is responsible for maintenance of this line including repair of leaks and locating prior to excavation. In some localities, the underground sewer line from the main line in the street to the house is owned by the homeowner and is a “private utility line”. Other examples of “private utility lines” are: lawn sprinkler piping, invisible pet fence wires, electric wires to lampposts or outbuildings, and propane lines from the tank to the house.
