Abstract
Gas utilities are currently facing a major challenge to their everyday operations due to the potential of horizontal cross-bores in sewer service laterals. In most States, sewer laterals are exempt from being marked, thereby leaving even the most professional horizontal directional drilling (HDD) contractors liable for hitting these unmarked, unknown lines. The insurance industry is rapidly becoming aware of this exposure and is subsequently making it difficult and costly for contractors to secure insurance for trenchless utility projects. State legislation mandates the marking and locating of underground infrastructure; however, the question of who assumes responsibility for marking and locating sewer service laterals is a contentious one. Numerous States are changing their laws to place this important task on the system owner/operator, who are in the best position to identify the location these laterals. This paper describes various issues related to sewer laterals and the consequences of horizontal cross-bores.
