Hydraulic criticality in a water network rehabilitation plan

摘要

Aging infrastructure is requiring US utilities to undertake asset management programmes to achieve efficient investment and minimize disruption to supplies. In this paper, Annie Vanrenterghem, Erik Bernard and Peter Galant describe a method for evaluating the impact of water main failure on service delivery when prioritizing pipes for rehabilitation in a water network. The method considers the direct impact of the broken main as well as impacts of a shutdown for the main repair on the rest of the network.
