This downloadable case study shows the 30% of cost (vs. traditional clean-to-inspect methods) that can be saved by inspecting 100% of your system but only cleaning the 20% which requires cleaning prior to inspection.
A study of 7 cities (a 2 million linear foot data set) found only 20% of the systems were significantly obstructed and 75% of pipes required no cleaning. A city with 200,000 LF of pipeline undertaking their first inspect-to-clean project would save $100,000 over the cost of a clean-to-inspect project.
- Inspect 100% of the system
- Clean the 20% significantly obstructed
- Save 30% of cost ($100,000 for a 200,000 LF system)
