Critical Resource For Implementing Water Pipeline Renewal Projects Published
March 11, 2016

The American Society of Civil Engineer’s (ASCE) new publication, Renewal of Potable Water Pipes: Manuals and Reports on Engineering Practice No. 132, outlines methods for using trenchless rehabilitation technology, to improve the safety and performance of pipelines carrying drinking water. Pipeline renewal methods provide cost-effective and environmentally friendly solutions compared with traditional open cut replacement and installation methods. This MOP outlines appropriate renewal technologies in use today with a focus on design, method applicability, and installation, so that water utilities can address the challenges of an aging infrastructure.

MOP 132 provides a detailed resource on planning, design and construction of trenchless technology. Topics include assessment inspection and evaluation; planning; preconstruction; construction and cleaning; pipeline-lining methods; post lining; and close out. The authors cover the following current pipe renewal methods; cured-in-place pipe (CIPP), spray-in-place (SIPP) with cement mortar lining or SIPP with polymer lining, sliplining, close-fit pipe, and fiber-reinforced polymer lining. The appendix includes a quick-reference chart comparing these trenchless renewal methods. Engineers, water pipeline owners, consultants, technicians, and operators contemplating a water pipeline renewal project should read this guide.
