Analysis of 400 million feet of sewer inspection data shows why proactive, condition-based maintenance outperforms reactive run-until-failure programs at preventing SSOs.

Effective sewer line maintenance is a vital aspect of collection system management and different strategies have evolved to increase the efficacy of cleaning programs. Traditionally, maintenance strategies operated on a run-until-failure basis. While these reactive programs addressed sanitary sewer overflows (SSOs) and backups as they occurred, they never proactively addressed the underlying causes.
