Advancing water main renovation and design

安大略和阿尔伯塔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。这些重要的配水管中有很大一部分（通常超过50%）已经使用了50多年，几乎没有维修、修复和/或翻新。管道老化和恶化导致水龙头处的劣质水显著增加，并增加了每年用于修复呈指数级增加的泄漏和破裂数量的水公用事业成本。挖掘旧管道以安装新管道，通常是在街道和高速公路下，对居民和企业来说是极其昂贵和破坏性的，并导致大量温室气体排放。明挖替换的替代方案是使用旧的劣化原位管道在管道内建造新管道，现在称为原位固化管道（CIPP）。本研究将探讨新的CIPP管道内衬设计和几种新的内衬产品的性能。

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.
