In an effort to mitigate the risk of cross bores, gas utilities must undertake expansive, and often costly cross bore programs. Cost for such an expensive project is traditionally assessed by examining two predominant factors: number of sewer inspections and the unit cost of each such inspection. There is, however, a third component that must be considered: program efficiency. This industry research briefing explores five major financial pitfalls in running a cross bore program, including the potential costs arising (risks) from gas releases resulting from a damaged cross bore. Topics covered in this white paper include the financial benefits of employing a research program, causes and effects of inefficient field (sewer) inspections, the role of data validation in inspection verification, lessons from Goldilocks and the use of video QC, and how to manage the resulting big data appropriately.
