SURVEY RESULTS FROM VARIOUS CITIES HELP DESCRIBE THE BENEFITS OF IMPLEMENTING A STRUCTURAL WATER MAIN REHABILITATION PROGRAM

摘要

The following paper will use results obtained from a study to describe the benefits of implementing a structural water main rehabilitation program. In 2009, a survey was sent to various cities in Canada that have carried out a water main structural rehabilitation program for a number of years. Each municipality was asked to answer a variety of questions including population, number of breaks, number of complaints and operational costs on their water distribution systems. Certain issues such as the number of breaks as the rehabilitation program progressed, in each of the cities, were examined. The results from the survey are shared in this paper to establish the various benefits to each of the participating cities. Benefits pertaining to water and construction cost savings are the main focus of this paper. The purpose of this paper is to raise awareness to the problems, issues and costs associated with old deteriorating water mains along with the technical and economical benefits of implementing a structural water main rehabilitation program.
