Abstract: Outage Management Using Network Data Model at Las Vegas Valley Water District


View Presentation

Keeping the water distribution network in good repair is a daily operation for the Las Vegas Valley Water District. Field crews responsible for repairs and preventative maintenance need to understand how to restrict water to the area where work will be done. A time-consuming process of referencing paper maps, phone calls to Operations engineers, and tacit knowledge has been the only way to plan for a network shutdown, until now. In disaster scenarios, such as in main breaks, shutdown is even more critical due to loss of water and more importantly impact to the community. Once in the field, crews find valves are broken making preplanning almost impossible.

We have developed a Web-based end-user GIS application utilizing custom valve shutdown analysis based on the Oracle Spatial Network Data Model (NDM). This enables users to answer the shutdown question much more efficiently. A user can quickly simulate different shutdown scenarios and develop a shutdown plan in just minutes. The custom algorithm uses Network Data Model functionality to identify valves that must be closed as well as identifying impacted customers and fire hydrants. This innovative use of the Oracle Spatial Network Data Model for outage and crisis management has quickly become a highly valued asset for the organization.
