Charlotte Water Successfully Transitions from Geometric Network to ArcGIS Utility Network

As the largest public water and wastewater utility in the Carolinas, Charlotte Water (CLTWater) serves over a million customers in the City of Charlotte and greater Mecklenburg County, including the towns of Matthews, Mint Hill, Pineville, Huntersville, Davidson, and Cornelius. The utility has operated since 1889 and maintains over 9,000 miles of water mains and wastewater mains, over 18,000 hydrants, 17 water storage and pumping stations, and 74 wastewater lift stations.

Challenge

Geographic information system (GIS) manager Shannon Martel and her team of nine experts are responsible for a number of applications for CLTWater, managing everything from CCTV to automatic vehicle location. Geospatial data is a very high-value asset for Martel and her team. Martel, as well as the organization as a whole, maintains a GIS-centric approach to all applications and data.

To support a variety of functions, CLTWater relies on several integrations with its GIS data. Cityworks is the utility’s primary system for work order and asset management. It also uses Trimble’s e-Builder for project management, Hyland OnBase for records management, and Banner for financials and customer billing. Inspection data is collected from ITpipes, mobile devices, and contract companies. In addition to pulling in water quality data from the Laboratory Information Management System (LIMS) and the United States Geological Survey stream data, a collaboration between the City of Charlotte and Mecklenburg County provides broader information regarding water quality. Finally, the team has real-time data provided by the Geotab automatic vehicle tracking device.

A custom tracing task identifies connected customers from a secondary address source and generates a mailing list.

As part of a broader initiative within the City of Charlotte to eliminate ArcMap, it was time to move from the geometric network to ArcGIS Utility Network. This project was a significant task that required advanced planning, resources, stakeholder and user awareness, and the right team to make it happen. The objective was to understand all stakeholders and their needs and develop and execute an implementation plan to make the transition to ArcGIS Pro and Utility Network a success. 

A key requirement for CLTWater was to ensure minimal disruptions to normal operations during the transition. The team understood that to have a seamless transition, CLTWater would need a well-defined plan to update its data and IT infrastructure, redefine processes currently being done in ArcMap, and bring all users up to speed. 

Despite the challenges, CLTWater recognized that the investment in transitioning to ArcGIS Utility Network would provide clear benefits for modernizing network management, customer service, and future efficiencies. 

With its improved security measures, granular data options, precision, and ease of use, ArcGIS Utility Network was a natural choice for our utility.

The Partner

Charlotte Water partnered with Axim Geospatial to ensure that it received guidance from Utility Network experts. The Axim Geospatial team then evaluated the utility’s GIS program, data, and technical readiness while defining the pathway for adopting ArcGIS Utility Network. 

Then, Axim provided a structured approach to change management for Charlotte Water to ensure that the staff and the organization were prepared for the transition. This included assessing the impacts of migrating to Utility Network, ensuring stakeholders were involved in the process, and preparing the utility with training and support. 

After reviewing the utility’s current system architecture, Axim identified the functional and structural business requirements to determine an appropriate high-fidelity database design based on Esri’s base Utility Network models. The team then created a detailed implementation plan that determined the operational drivers needed for transitioning to Utility Network. This plan included data migration into the data models and guidance on the sequence of events and tasks required to adopt the model with minimal technical and business disruption. 

Understanding the state of its current data was critical to identifying the level of effort and how to best approach the rest of the project. Therefore, Axim performed a data readiness assessment of Charlotte Water’s data. Based on that review, Axim guided the utility to address the most critical data updates and what could be done at a later stage. While the Charlotte Water team cleaned up data, the Axim team worked on database design, designed elements, and determined how to perform the data mapping.

The Axim team also set up the extract, transform, and load (ETL) data migration tool, leveraging the specialized SSP Sync software to manage the transition. SSP Sync allowed Charlotte Water to create a publication version of the Utility Network parallel to its production geometric network environment. This functionality was essential to minimize risk and ensure minimal disruptions during the transition. 

Utility Network evaluates connectivity rules for each asset type, providing improved data quality.

Through iterative pilot implementations, the team loaded data and tested Utility Network in a sandbox environment that ran concurrently with its existing system. Doing so allowed the team to sort out bugs and resolve issues without affecting the live system. During this phase, the utility staff began to work with Utility Network with training support from Axim. The team developed standardized symbology, which Charlotte’s Cityworks team will eventually adopt. 

For nearly a year, Charlotte Water operated in both environments, cleaning up data and transitioning web apps to consume the new Utility Network. In addition to the Utility Network project, Axim assisted with an in-place upgrade of Charlotte Water’s ArcGIS Enterprise environment.

“With Axim Geospatial’s support, we had all the tools, training, and resources we needed to successfully transition to Utility Network.”

The plan Axim developed for Charlotte Water empowered a smooth transition.

The Result

Charlotte Water became the first large municipal water and wastewater utility in the United States to be fully in production with ArcGIS Utility Network. Despite the early challenges, Utility Network continues to provide numerous benefits for the utility and its customers.

With its new high-fidelity data model, the utility can access more accurate representations of the conditions and functionality of real-world assets. Additional benefits include the following:

“Utility Network continues to prove its value to our organization and our customers, and we’re glad to have implemented it at Charlotte Water.”

Shannon Martel, GIS ManagerCharlotte Water

Overall, Charlotte Water’s transition to ArcGIS Utility Network has resulted in a more efficient and secure system for network management. Most importantly, the team’s GIS system now follows modern IT best practices relying on a services-based architecture. 

Furthermore, Charlotte Water now has the foundation for a digital twin of its physical asset infrastructure. The utility is at the forefront and positioned to leverage ArcGIS Utility Network to dramatically improve workflows throughout the organization. The utility continues working to integrate other business systems dependent on the GIS to begin using Utility Network, with the Cityworks Asset Management System as the prioritized system.
