AC Watermain Break Probabilities and Replacement Planning Tools - Nanaimo's Experience

Description:In British Columbia, there are many communities with significant amounts of AC watermain in their inventory. Much of this AC watermain was installed in the 60's and 70's and is reaching an age where it can be problematic. Nanaimo has 140 km of AC watermains, which account for the majority of the City's watermain breaks. These breaks are a substantial hazard and liability for the community. To better understand what causes the breaks we completed a study of past breaks and the risk factors associated with them. This study resulted in the development of a decision making tool for capital replacement of AC watermains. This paper is a case study of Nanaimo's experience with managing the AC watermain asset and development of the decision making tool for capital replacement.
