Demonstration and Evaluation of Innovative Rehabilitation Technologies for Water Infrastructure Systems
Publication: Journal of Pipeline Systems Engineering and Practice
Volume 8, Issue 4
Abstract
The needs associated with the deteriorating water infrastructure are immense and have been estimated at more than $1 trillion over the next 20 years for water and wastewater utilities. To meet this growing need, utilities require the use of innovative technologies and procedures for managing their systems. The U.S. Environmental Protection Agency (USEPA) developed a demonstration program for pipe rehabilitation methods to help fill this gap. The program’s objective is to evaluate pipe rehabilitation technologies that can increase the effectiveness of the operation, maintenance, and renewal of pipelines. This paper provides an impartial assessment of the effectiveness and cost of four innovative technologies for water distribution and wastewater collection pipes. The technologies demonstrated include spray-on polymeric lining and cured-in-place pipe (CIPP) lining for water mains; and spray applied geopolymer mortar and an internal pipe sealing system for wastewater mains.
