Management and renewal of urban water infrastructure

Resumen
Large-diameter transmission water mains and small diameter distribution mains are essential components of urban water supply systems. Large proportions of these pipes have average ages greater than 50 years and their condition is rarely known with any accuracy. As water mains age, they deteriorate. An immediate question that arises from the utility¿s perspective is which pipes require attention and when. This question is discussed in terms of failure management for small diameter mains and failure prevention for large diameter mains. <br/> This paper focuses on the failure management and prevention strategies for water mains. The most common measure of deterioration of small diameter distribution mains is the frequency of failure, which can be proactively mitigated using cathodic protection to control external corrosion. This paper highlights the importance and the benefits of data collection and how subsequent analyses using models can help plan the renewal of deteriorated water mains. These analyses can assist water planners to identify which pipes to renew, when and how, subject to service levels and budget constraints. These analyses are discussed in the context of a case study.
