We all want simplicity, but sewers fail in complicated ways.

Rather than focusing on an isolated metric, like estimated infiltration rate, sewer condition assessment and rehab planning demand a qualitative approach—one that accounts for a broad range of observations.

This white paper explains what quantitative and qualitative mean in sewer condition analysis, and presents case studies for each: FELL-41 and CCTV.
