CIPP Technology for Water Pipe Rehabilitation
In the past decade the need to specifically address aging and deteriorating water infrastructure has become more apparent*. This webinar focuses on next generation cured-in-place pipe technology available today for water distribution and transmission main rehabilitation.
Cured-in-Place Pipe (CIPP) technology has been employed in gravity sewer pipe rehabilitation for over 40 years. By 2007, CIPP was recognized as the most used rehab technology with estimates of over 10 million lineal feet of lining being performed in the USA per year and growing. The natural evolution of CIPP was to develop systems to perform as well in pressure pipe as it had been in gravity pipe. The challenges include increased control during installation, non-shrink resins, long-term composite strength addressing both internal and external loads and the capability to meet stringent regulations for contact with potable water.
This webinar provides details on key standards and quality controls necessary for successful application of CIPP technology in water pipe. Information including resin selection, liner materials, equipment meeting the first CIPP wet-out standard ASTM F2994, installation practices, service connections and testing will be presented. Case histories on both small diameter distribution mains with robotic service reconnection and large diameter transmission lines provide valuable insight into the evolution of CIPP that will allow engineers to create a logical and cost-efficient strategy for the complete structural repair and preventative maintenance of aging and deteriorated water infrastructure.
* According to the American Society of Civil Engineers (ASCE), as released in its 2013 Infrastructure Report Card, “…at the dawn of the 21st century, much of our drinking water infrastructure is nearing the end of its useful life.” There are an estimated 240,000 water main breaks per year (650+ per day) in the United States. Assuming every pipe would need to be replaced, the cost over the coming decades could reach more than $1 trillion, according to the American Water Works Association (AWWA).
