Innovation in trenchless rehabilitation techniques has helped hundreds of towns, cities and water utilitiesin North America save millions of dollars in construction costs and reduce their water loss in distribution systems byusing environmentally friendly cured-in-place pipe (CIPP) technology.Large water utilities have struggled to maintain their water distribution systems to a point that some lose as much as 40%of the water treated. The lost water results in lost revenue and added pumping and treatment costs both at the watertreatment plant and, too often, at the sewage treatment plant. This situation is costly and environmentally unsound.This paper demonstrates, with the use of a case study, how a large water utility used a rehabilitation approach tosignificantly reduce its water loss. Actual test results demonstrate how water loss was reduced by comparing before andafter water loss measurements of water distribution segments that were rehabilitated using a CIPP technology.Further to the reduction of water loss, the paper also presents how the water utility saved millions of dollars inconstruction costs, the CIPP technology resulted in considerable savings in greenhouse gas emissions when compared tothe open cut replacement method and the water utility benefited from the other trenchless advantages.
