Interstate Engineering Certified for Cured-In-Place Pipe Installation Inspection

Sixteen Interstate Engineering employees are certified for cured-in-place pipe installation inspection. The training, administered by the National Association of Sewer Service Companies (NASSCO), brought engineers and construction observers together for an intensive two-day training to strengthen their knowledge of the cured-in-place pipeline renewal technology.

The Inspector Training and Certification Program (ITCP) for cured-in-place pipe installation is the first of a number of pipeline renewal technology programs being developed by NASSCO. The ITCP course covers specific areas of expertise that are needed to ensure a cured in place project is built correctly and meets the requirements of the contract documents.

“Given the advancements in the cured-in- place technology, we see this as a long term solution,” explained Lonni Fleck, Vice-President and Principal Engineer with Interstate Engineering.  “Compared to traditional open cut methods and other trenchless methods, cured-in-place technology can provide a more economical and less disruptive solution.  Having our staff certified provides clients with further assurances that the work being performed accurately and to specifications. This translates into a more sustainable product.”

Cured-in-place pipe technology was developed in England in the 1970s. With successes abroad, this technology was brought to the United States in the mid-1970s.  Liner and resin technology have improved over the years, providing more cost effective installation that is less risky for the construction industry.  Furthermore, industry education and contractor familiarization have improved to provide 50-plus year solutions to renew old deteriorated and leaking pipelines. Though cure-in-place pipe technology was initially used to rehabilitate sanitary sewer systems, the technology has been expanded to include almost any pipeline that needs to be renewed.  Interstate Engineering will continue to stay educated on new developments including water main rehabilitation.
