Presentation: Tony Araujo, Vice President Business Development with Paragon Systems Testing, will be presenting an overview of CIPP quality considerations. During his 42 years in the independent materials testing business, Tony has been involved in the quality assurance testing of a rehabilitation materials since 1995. Tony has published on the topic of CIPP QA testing at industry conferences and participates on ASTM, AWWA, NASTT and NASSCO standards writing committees.

The American Society for Quality defines quality assurance as “all the planned and systematic activities implemented within the quality system that can be demonstrated to provide confidence that a product or service will fulfill requirements for quality”. Requirements for quality in sewer CIPP projects typically revolve around achieving a minimum design life of 50 years and are defined within the Owners construction specification or tender documentation.

Research has demonstrated that the physical properties of installed sewer CIPP liners measured in laboratory tests can vary to a greater degree than more traditional pipe materials. To incorporate this characteristic of sewer CIPP installations, many owner’s quality requirements have been evolving to ensure that their CIPP projects achieve design life with an acceptable degree of confidence. Unlike the ASTM and ISO standards and specifications which are incorporated within owner specifications, there are no industry-wide universal approaches employed by owners to define their sewer CIPP quality assurance best practices.

This presentation examines the quality assurance tests and the sewer CIPP quality assurance best practices employed by four Canadian municipalities, Edmonton, Montreal, Toronto and Winnipeg in current sewer CIPP projects and describes the quality assurance outcomes of the different approaches.
