Introduction to Stormwater Utility Network Foundation

Stormwater Utility Network Foundation can be used to accelerate stormwater utility network implementations.

It includes a data model that configures ArcGIS Enterprise and the ArcGIS Utility Network to represent stormwater networks. It deploys foundational services, simplifying the creation of additional web and mobile apps and provides a desktop data editing environment.

Starting with Stormwater Utility Network Foundation means organizations don't have to spend their time and implementation budget on building custom data models and information products.

Deploy the solution

This solution can be deployed in your ArcGIS organization.

Deploy the solution

See Deploying a solution for more information.

Requirements

Stormwater Utility Network Foundation requirements are determined by the type of deployment.

Single-user deployment requirements	Enterprise deployment requirements
ArcGIS Pro 3.5 or ArcGIS Pro 3.7	ArcGIS Enterprise ArcGIS Pro 3.5 or ArcGIS Pro 3.7

Note:

To deploy this solution, you must have an ArcGIS organizational account. After deploying the solution, you can download it from your organization and begin using it in ArcGIS Pro.

Information products

Stormwater Utility Network Foundation includes the following information products:

Item	Description	Minimum user type
Stormwater Utility Network Essentials	A zipped file with an ArcGIS Pro project package, asset type map, style files, sample data and an essentials asset package geodatabase that supports a stormwater system.	Professional
Stormwater Utility Network Expanded	A zipped file with an ArcGIS Pro project package, asset type map, style files, sample data and an expanded asset package geodatabase that supports a stormwater system.	Professional

When you deploy this solution in your ArcGIS organization, you also get a solution item that organizes the key information products and summarizes all the ArcGIS items (applications, forms, projects, maps, feature layers, feature layer views, and so on) included with the solution. The solution item also illustrates any dependencies items have on each other.

Release notes

The following are the release notes:

Version	Description
2.0 (Mar 2026)	The solution now includes Stormwater Utility Network Essentials, which provides a fundamental schema to help model stormwater systems. The current model has been renamed to Stormwater Utility Network Expanded and includes the following changes: The Lifecycle Status field has been renamed Asset State in all Utility Network feature classes. The Construction Status field has been renamed Asset Lifecycle Status in all Utility Network feature classes. The Construction Status network attribute has been removed to reduce the number of dirty areas created during status updates. The ArcGIS Pro project now includes a single Asset Type map to simplify setup and configuration. Removed tasks from the ArcGIS Pro project and replaced them with online documentation to provide more accessible and up-to-date resources. The Utility Data Management Support (UDMS) toolbox has been removed from the solution and can now be downloaded from the GitHub page. Data dictionaries have been removed from the solution and are now available in an online data dictionary. The BMP Point asset group now includes a single asset type named BMP Point, and the type of BMP is defined through the design type field. This structure simplifies BMP editing workflows. Renamed BMP Inlet to Inlet to support additional use cases. Converted the elevation field from short to double to support decimal input of elevation values. Add classification attribute to StormwaterDevice for Catch Basin to track the level classification of catch basins Added the following new Asset Groups for enhanced functionality: Service Connection, Lateral, Fitting, Gate, Outfall, System Outflow. Separated Gravity, Force and Perforated Pipes into their own Asset Groups to better support rules and workflows. Added new network categories to support ArcHydro. The values in the Activate Value domain have been updated and the network attribute value has been moved to inline to better support overflow modeling. Changed terminal name Directional Dual Terminal to Pipe Directional Dual Terminal to align with terminals used in Sewer. Changed terminal name Bidirectional Dual Terminal to Pipe Bidirectional Dual Terminal to align with terminals used in Sewer. Adjust valid paths for Directional Manhole Terminal to ensure proper valid paths. Change symbol rotation to type of double for more accurate rotation values. Converted the tier definition type from partitioned to hierarchical to support additional subnetworks.
1.4 (Aug 2024)	The following updates have been made to the Utility Data Management Support toolbox version 3.3.1: An issue was resolved with the Simple Data Mapping tool that was caused by running the tool in a cloned python environment. A new option to generate a terminal pop-up was added to the Configure UN Layers tool to visualize terminal information. A new tool was added called Copy Fields and Domains From Mapping which uses the Data Mapping workbook to copy fields from the source workspace to the target asset package.
1.3 (Jun 2024)	The subnetwork definitions' summaries have been removed because they are not required and can slow down the update subnetwork process. If summary information is required, it can be calculated through a trace. The Lifecycle and Construction status domains have been updated to align with other utility network foundation solutions. The lifecycle domain codes have been reduced to a minimum set of codes, defined by bits, to identify if a feature is in or out of the subnetwork/trace. The construction status domain is used to defined additional states an asset may be in. The Lifecycle Status network attribute has been moved to Inline to reduce database queries through trace and update subnetwork properties. The Device Asset Group, Line Asset Group and Junction Asset Group/Type network attributes have been removed as network categories. The system Asset Group/Type network attributes should be used for tracing and subnetwork definitions settings. The subnetwork definitions' condition barriers have been revised to aligned with the code changes of the Lifecycle Status domain so that the definition is valid. The Data Dictionary has been replaced with reports generated from the Generate Schema Report geoprocessing tool.
1.2 (Mar 2023)	A new Utility Data Management Support toolbox to support ArcGIS Pro 2.9 and ArcGIS Pro 3.1.
1.1 (Nov 2021)	Name changed from Stormwater Data Management for ArcGIS Enterprise to Stormwater Utility Network Foundation.
1.0 (Jun 2021)	The first release of Stormwater Data Management for ArcGIS Enterprise. The data model in the solution has been updated to version 4. For a full list of updates, refer to the change log.
