Compared to crawler-only inspection, the Phased Assessment Strategy for Sewers (PASS) approach reduces assessment costs by roughly 34% and boosts productivity about 17%. This free, printable infographic can be used to understand the value of the PASS workflow and communicate it to your team.
PASS divides sewer assessment into three phases:
- Phase 1: Zoom camera survey of all lines to see which need further attention.
- Phase 2: Post-cleaning video nozzle assessment of questionable lines.
- Phase 3: Thorough crawler inspection only for pipes that need it.
With this phased approach, you can focus attention and resources on the pipes that need it most. The infographic illustrates step-by step how each phase results in productivity gains and cost savings. Download a copy today:
