Canada and the United States:

The CSA plus 4012 Visual Sewer Inspection Technical Guide introduces the concept of distress and defect "severity" and "extent". This provides a framework to organize distress and defect codes into "primary failure modes", and maps the PACP® codes into the framework - a significant addition to accepted practice in Canada.

The PACP® provides a standardized, consistent way to evaluate sewer pipe conditions and manage TV inspection results, with the goal of providing comprehensive, reliable data to describe the sewer pipe. This data helps in prioritization, planning, and renovation of wastewater collection systems.

Exclusive Offer for Municipalities:

Municipal staff and/or their authorized agents may purchase an electronic Version of the PACP® Canadian Edition without taking the classroom training.
