摘要

The Miami-Dade Water and Sewer Department (MDWASD), the largest water utility in the southeastern United States, supplies potable water service to over 2.3 million customers in southern Florida. Water is distributed through a distribution network comprised of more than 5,300 miles of pipeline. MDWASD is constantly working to address the identification of pipeline renewal needs in new and innovative ways. MDWASD recently developed a plan to renew large amounts of the system pipeline network that uses a computerized, risk-based pipeline asset approach mixed with a set of engineering decision criteria to identify areas of this very large system to focus the work on. This paper provides a detailed description of the development of the pipeline renewal program leveraging MDWASD's geographic information system (GIS) database. The approach utilized historic records of past pipeline breaks and failures as well as spatial analysis to rank each pipeline for its likelihood of failure. The consequences of failure were then calculated based on a number of factors such as the amount of system demand affected in a pipeline outage and the proximity to critical infrastructure, human activity, roadway traffic and commerce. The estimated likelihood of failure for each pipeline was then multiplied by the consequence of each pipeline failing to rank each segment within the 5,300 miles of the system. The scores were then applied to the MDWASD GIS for tracking and reference.
