A crawler-only sewer inspection program isn't always the best use of your resources. It may be time for a new approach: the Phased Assessment Strategy for Sewers (PASS) is designed to help you make the most of your time and budget, while improving response time for inspection and repair.

PASS reduces costs roughly 34% and boosts productivity about 17% compared to crawler-only inspection. The PASS approach is broken down 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

Start directing your resources where they're needed most and avoid unnecessary cleaning and inspection time. Learn more about the PASS approach in Envirosight’s free whitepaper, available for download:
