Understanding the Utility Network: A Guide for Water Utilities AN ESRI WHITE PAPER 7 Asset Packages A utility network can be created and configured manually to meet a utility's asset management requirements, business demands, and modeling needs. However, this involves a high level of effort and familiarity with the utility network data model. To streamline the implementation of the utility network, Esri provides industry configurations for water distribution, sewer collection, and stormwater. Each configuration includes asset packages, maps, and applications configured for the specific industry. The asset packages provide an industry-specific utility network data model schema as well as asset classification, network rules, network definitions, and subnetwork properties for the utility network. The asset packages are delivered as file geodatabases and can be extended as needed. Removing features and fields from the asset package schema is not recommended as it may affect functionality built into Esri's ArcGIS Solutions for Water. Solutions ArcGIS Solutions for Water is a package of workflow templates consisting of maps, apps, and tools designed to get organizations up and running with a variety of common workflows shared by water utilities. Solutions for water utilities help improve operations and customer service, as well as maximize efficiencies. ArcGIS Solutions for Water can be downloaded from solutions.arcgis.com/#Water or deployed using the ArcGIS Pro Solution Deployment tool add-in (solutions.arcgis.com/shared/help/deployment-tool). Perform analysis to make better decisions The utility network includes advanced analysis tools that provide new levels of detail and visibility for network operations. Tracing analysis can identify the valves that need to be closed to isolate an area in the event of a water main break. Traditional upstream and downstream traces are also available to locate the source of flow or follow the path of resources downstream. The utility network includes a tracing framework for configuring detailed tracing analysis through geoprocessing. Subnetworks A utility network is a collection of subnetworks through which a commodity flows. Examples of subnetworks include pressure zones, district metering areas (DMAs), and sewer basins. Once subnetworks are defined, additional analysis can be performed such as identifying service connections, valves, and hydrants or adding the total length of water lines in a given pressure zone or DMA. Subnetworks are dynamic and can be altered by the opening and closing of devices such as valves. A utility network uses the sources of the commodity to define the start points of a subnetwork and traces down to the ends (or sinks) of a subnetwork to discover its entire extent. When a valve is changed, the extent of a subnetwork can be recalculated. Devices that define the extent of resource flow within a subnetwork
