ArcGIS Utility Network Migration - The Hunter Water Story
Hunter Water Corporation, the providers of water and wastewater services to a population of almost 600,000 people in New South Wales, Australia, engaged 1Spatial, the global provider FME and other geospatial software and solutions for improved data governance. This presentation will outline how 1Spatial collaborated with Hunter Water in their ArcGIS Utility Network (UN) Migration as part of their GIS Transformation Project. This project allowed Hunter Water to leverage the latest digital geospatial technologies to visualise and analyse their networks and assets. Validation of the data being loaded into the new GIS platforms was completed using 1Spatial's skills and technologies. Under this partnership, Hunter Water leveraged 1Spatial's expertise and technology in the cloud to streamline its data migration process, ensuring the efficient transfer of critical information for its operations. This strategic move aligned with Hunter Water’s commitment to delivering the highest quality water and wastewater services to its customers across the Lower Hunter region. This presentation will detail the issues encountered by Hunter Water in their project of migrating their existing system to the new ArcGIS Utility Network. The methods they adopted to remedy their issues and how 1Spatial’s technical expertise and tools, assisted Hunter Water to maintain data quality and accuracy while facilitating data migration and integration ensuring the integrity of its information assets.

- 5. THE IMPORTANCE OF DATA QUALITY The Utility Network is built on a foundation of data quality rules that maintain the integrity • There are in-built data quality rules (geometries and attributes) • There are 5 categories of Utility Network rules that define the relationships that are allowed between features in the network • Data quality issues will result in ‘dirty area errors’ • Utility Network Rule non-conformances e.g. line A cannot connect to point B • Poor data quality e.g. self-intersecting lines • Importantly, these errors can stop key functionality from working Esri’s best practice states: For a properly functioning utility network the error count should be as close to 0 as possible. Error counts greater than 10,000 have severe performance and functionality implications. ArcGIS Utility Network Migration - the Hunter Water Story
- 6. CHALLENGES – CONFIG ERRORS • Reflux Valves are directional. The upstream side is configured in the data model • The lines are assigned to a terminal of the valve. (Inlet / Outlet) • In this example, the terminal assignment is incorrect. The subnetwork (purple line) is not able to continue past the valves. • No errors are generated.

- 7. CHALLENGES – TOPOLOGY ERRORS • System Valves are placed on top of each other • Topology error 25: Stacked point Features detected • "Error" Dirty Areas created (Red striped boxes) • The update subnetwork process will detect these errors and the subnetwork will not build.

CLEAR & ACCURATE REPORTS Find and fix data quality issues efficiently Field Description OBJECTID A unique identifier for every point in the report geometry A point geometry highlighting the location of the failing feature Class The original Class that the failing feature belongs to OBJECTID of failing feature The original OBJECTID of the failing feature Reason for failure The reason the feature failed the Rule Rule name The name of the Rule that the feature failed Rule description A description of the Rule that the feature failed Rule category The category of the Rule that the feature failed ArcGIS Utility Network Migration - the Hunter Water Story
- 10. THE 1SPATIAL SOLUTION Publication & additional configuration UN Readiness UN Migration UN Validation Source Data Asset Package Get your existing data fit and ready for migration into ArcGIS Utility Network (UN). The UN is built on a foundation of data quality rules – if your data isn’t clean, it will present many errors in the system and hinder your progress. Data-driven schema transformation. Move your data from its current format into your Utility Network target model. By utilising the Asset Package, we can iterate until we're confident to go-live. Ensure that no data quality issues have been introduced during the migration and check against the UN Rules. It is much easier to capture and fix any issues before publishing data into the Esri system. ArcGIS Utility Network Migration - the Hunter Water Story

Recap: Harnessing Data Integration Project delivered: ● Data Readiness for UN Migration ● FME enables the GN & UN to exist side by side ● Data is maintained in a single location ● Legacy Applications remain unaware & unaffected of the migration. ● Lowers risk by enabling sequential cut-over/remediation of existing applications. ● Support newer applications and users with UN ArcGIS Utility Network Migration - the Hunter Water Story
