Challenge
A mid-sized municipality managing over 500 km of sewer mains was struggling with rising emergency repair costs. Reactive maintenance — fixing pipes only after they failed — was consuming 80% of the annual infrastructure budget. They needed a systematic approach to understand the true condition of their sewer network and prioritize repairs based on data, not urgency.
Solution
The municipality deployed two DP-C200 Crawler systems with DP-Report Suite software. Over 12 months, their inspection teams systematically surveyed 120 km of priority trunk sewers and feeder mains.
The DP-C200’s HD camera and 10x optical zoom enabled detailed defect documentation, while the integrated sonar profiling identified sediment buildup and infiltration points that would have gone unnoticed with standard CCTV.
Results
After the first year of systematic inspection:
- Emergency repairs dropped 67%, as small defects were identified and repaired before they became failures
- $2.4M in annual savings from reduced emergency call-outs, traffic management, and property damage claims
- A data-driven 5-year rehabilitation plan based on objective PACP-coded condition data
- The inspection program paid for itself within 6 months
Key Takeaway
“Before Dana Pipe, we were fighting fires every day. Now we have a plan, we have data, and we’re actually getting ahead of the problem. The DP-C200s paid for themselves in the first six months.” — City Utilities Director
