Factors To Consider For Condition Assessment Of Water And Sewer Systems

By David Totman

Back in the day, we pretty much had nothing but good ol' CCTV as our primary method of inspecting sewer pipes giving us data to assess their condition; IF the pipe didn't fog up for good video and/or the VHS tape got eaten in the player. Water pipes?

You either guessed on intuition or methodically took pipe wall samples ("coupons") to analyze corrosion and wall thickness loss. "Listening sticks" have been around forever, and they were for leak detection more than an actual condition assessment.
