Every city and town in Ontario and Alberta, and across Canada and North America, supplies potable water to residences and business through thousands of kilometres of distribution and transmission pipelines. A large percentage (often over 50%) of these critical water distribution pipes have been in service for over 50 years with little to no maintenance, rehabilitation and/or renovation. Pipe aging and deterioration has resulted in a significant increase in poor quality water at the tap and increased annual water utilities costs to fix an exponentially increasing number of leaks and breaks. Digging up old pipelines to install new pipelines, typically under streets and highways, is extremely costly and disruptive to residents and businesses and results in large greenhouse gas emissions. An alternative to open-cut replacement is to use the old deteriorated Insitu pipe to build a new pipe within the pipe known now as Cured-In-Place Pipe (CIPP). This research will investigate new CIPP pipe lining design and the performance of several new lining products.

安大略省和阿尔伯塔省的每个城镇，以及加拿大和北美的每个城镇，都通过数千公里的分配和输送管道为居民和企业提供饮用水。这些关键的配水管道中有很大一部分（通常超过50%）已经使用了50多年，几乎没有维护、修复和/或翻新。管道老化和劣化导致自来水质量显著增加，并增加了每年用于修复泄漏和破裂数量成倍增加的水电费。挖掘旧管道来安装新管道，通常是在街道和高速公路下面，成本极高，对居民和企业造成破坏，并导致大量温室气体排放。另一种替代方法是使用老化的原位管道在管道内建造新的管道，现在称为就地固化管道（CIPP）。本研究将探讨新型CIPP管道衬砌设计及几种新型衬砌产品的性能。
