Case Study: PG&E reduces sewer cross bore review time by 70% with SewerAI

PG&E reduces cross bore review time by 70% with SewerAI

PG&E, a major combined natural gas and electric utility, faced the critical safety challenge of detecting utility cross bores in its sewer laterals. The time-intensive manual review of over 1,040 inspection videos was inefficient. PG&E partnered with SewerAI to address this challenge using its AI-powered PIONEER platform and AutoCode™ defect detection engine.

SewerAI implemented a two-step workflow where its AutoCode AI analyzed footage to flag potential cross bores for validation by technicians. This solution reduced manual review time by 70%, from 108 hours to just 32 hours. The AI achieved 97.5% accuracy, and the combined AI-plus-human review process resulted in 100% final detection accuracy, allowing PG&E to scale its safety program efficiently.
