What has become known as the "crossbore" issue, continues to draw attention of providers of underground piping systems, particularly sanitary sewer services, and the contractors who make utility installations using horizontal directional drilling (HDD) and pneumatic piercing tools.rnWhile all parties agree crossbores - boring through an existing sewer line and placing electrical cable or natural gas line inside sewer pipes - pose a serious safety issue, how to avoid them remains a controversy with no immediate prospects for resolution.rnKey to the prevention of crossbores is accurately locating and marking of existing sewer laterals.rnYet many sewer service providers refuse to locate laterals prior to construction, often taking the position that because the laterals frequently cross private property, it is not their responsibility. Some state one-call legislation is unclear regarding responsibility of sewer laterals. Many states do place location responsibility with the service provider, but those statutes are not consistently enforced.
