The Renewal of Water Mains Using Trenchless Cured in Place Pipe: a Sustainable Solution

Abstract

For years now, there has been a sustainable way of renewing drinking water mains. The use of cured in place pipe (CIPP) allows owners to reduce the emissions of greenhouse gas and contribute greatly to the reduction of lost water or unaccounted for water. Furthermore, earthquake prone regions of the world are now looking for alternatives to traditional open-trench replacement for drinking water mains. In this paper, we will introduce a cured in place technology specifically designed for the renewal of water mains in earthquake prone regions. We will further elaborate on the qualities required to design a structural liner that can take the loads, pressures and movement of water mains while maintaining the water tightness of the system. Finally, we will show how using trenchless CIPP can save on green house gas emissions.
