"Cross-bores" occur when gas lines intersect with sewer lines, and can cause blockages and even natural gas leaks. A large California utility is committed to finding and relocating cross-bores. The company has performed 140,000 of ~150,000 inspections needed in San Francisco, but the remaining 10,000 sites are the most challenging and many have few or no records.
The company's cross-bore identification process is intensive and manual, using existing records (where present), sewer camera inspection, potholes, and open trenching as a last resort. The current strategy is expensive and time-consuming, so the company engaged Exodigo to investigate suspected cross-bores. Exodigo was asked to identify lines that needed potholes to minimize trenching and test Exodigo's cross-bore prevention, identification, and relocation capabilities.
