CIPP Sectional/Point Repairs: Critical Factors--Finally Explained

A 1999 report from the American Society of Civil Engineers indicated at that time that the nation's 500,000 plus miles of sewer lines had an average age of 33 years. However, many cities today are maintaining and operating collection systems with sections that are nearly 100 years old. Significant proportions of these pipe segments have well exceeded their original design life and are failing at an alarming rate. To compound the problem, the line segments in question are not failing entirely from end to end, the failures and defects are occurring at specific points within the segment and with varying lengths. In the past, excavation or open-cut methods have been universally accepted as a means to address these problems. These traditional methods for rehabilitating or maintaining services have proven to be very costly, time consuming and disruptive. In addition, the true social costs and environmental impact of this type of repair method is not taken into full account and the effects are all too often realized during the construction and restoration phases of the project. This has resulted in an ever-increasing demand for proven methods of Cured in Place Pipe (CIPP) rehabilitation, which has the capability of restoring structural integrity for a particular "point" or "section" of varying lengths in a line segment without the need for traditional excavation or CIPP lining from manhole to manhole. Trenchless methods provide many advantages as well as being a safe environmentally friendly sound approach for rehabilitating underground services. Sectional repairs typically range from 3 to 30 ft in length with diameters ranging from 6 to 48 in.
