In recent years, the utility has taken a thoughtful, phased approach to modernization thanks to dedicated, integrated internal teams. They upgraded their geographic information system (GIS), transitioned to ArcGIS Utility Network, and deployed map-based field workflows that seamlessly connect asset management and operations. Building on these foundations, Pennichuck is expanding its digital transformation into facilities, using digital twins to create a more complete and connected view of its systems.<\/p>\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.esri.com\/en-us\/industries\/blog\/wp-content\/uploads\/2025\/12\/Pennichuck-pump-station-1024x683.jpg\" alt=\"\" class=\"wp-image-580602\" srcset=\"https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/Pennichuck-pump-station-1024x683.jpg 1024w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/Pennichuck-pump-station-300x200.jpg 300w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/Pennichuck-pump-station-768x512.jpg 768w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/Pennichuck-pump-station-1536x1024.jpg 1536w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/Pennichuck-pump-station-2048x1365.jpg 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Pennichuck Water Works Historic Dean and Main Pump Station<\/figcaption><\/figure>\n\n<h2 class=\"wp-block-heading\" id=\"h-modernizing-asset-management-in-facilities\">Modernizing Asset Management in Facilities<\/h2>\n\n<p>Pennichuck had already made significant strides in modernizing its distribution network model. This included upgrading their enterprise GIS, converting to ArcGIS Utility Network, upgrading to a GIS-centric work and asset management platform, and creating map-first workflows for work orders and inspections. Although these areas of the operation had been strengthened, facilities such as pump stations and treatment plants lagged behind. Represented mostly as points on a map, these facilities were still reliant on operator expertise and supported by limited, system-level tools.<\/p>\n\n<p>Unlike pipelines and valves in the distribution system, Pennichuck\u2019s facilities did not start from the same level of detail within GIS and asset management systems. In addition, they contain layers of complexity within a single location with multiple assets working together inside a single \u201ccontainer.\u201d<\/p>\n\n<p>Existing systems offered limited visibility into this environment, due to their lack of development and reliance on effective but manual operational processes. In particular, the utility network lacked detailed representations of station-level assets, making it difficult to visualize how equipment fit together or to connect daily tasks such as inspections and work orders to the bigger operational picture.<\/p>\n\n<p>This represented a gap when compared to the overall strategy, and Pennichuck knew it. Now, they were ready to tackle it as an opportunity to improve operations and reduce risk by integrating facilities into the GIS environment. Doing so would provide staff with a unified view of all assets and enable them to work with the same clarity in the field and inside a plant. They saw the opportunity to build a strong foundation while simultaneously evaluating and improving their asset management program for facilities and vertical assets.<\/p>\n\n<h2 class=\"wp-block-heading\" id=\"h-partnering-for-success\">Partnering for Success<\/h2>\n\n<p>Bringing this vision to life required the right expertise, and Pennichuck turned to LandTech, an Esri partner with deep experience in reality capture, 3D modeling, and GIS-based digital twin development. With a background supporting water utilities across New England and beyond, LandTech brought both the technical skills and industry insight needed to succeed.<\/p>\n\n<p>From the start, the partnership was a true collaboration. Pennichuck\u2019s teams worked side by side with LandTech, testing and refining models and applications together. This hands-on, iterative approach ensured the final solution not only mirrored real-world workflows but also felt intuitive for staff, setting the stage for smooth adoption and lasting impact.<\/p>\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"791\" height=\"1024\" src=\"https:\/\/www.esri.com\/en-us\/industries\/blog\/wp-content\/uploads\/2025\/12\/ScanToRevit-791x1024.png\" alt=\"\" class=\"wp-image-580603\" srcset=\"https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/ScanToRevit-791x1024.png 791w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/ScanToRevit-232x300.png 232w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/ScanToRevit-768x994.png 768w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/ScanToRevit-1187x1536.png 1187w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/ScanToRevit.png 1275w\" sizes=\"auto, (max-width: 791px) 100vw, 791px\" \/><figcaption class=\"wp-element-caption\">Graphic Showing Transition from Scanning to Point Cloud to 3D Model<\/figcaption><\/figure>\n\n<h2 class=\"wp-block-heading\" id=\"h-exploring-capabilities\">Exploring Capabilities<\/h2>\n\n<p>Pennichuck launched a pilot project to explore the role of digital twins in facilities management. The effort focused on three key sites: a pump station, a booster station, and the finish water pumping station at the main treatment plant. The workflow followed a structured but adaptable path:<\/p>\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"109\" src=\"https:\/\/www.esri.com\/en-us\/industries\/blog\/wp-content\/uploads\/2025\/12\/workflowdiagram-1024x109.png\" alt=\"\" class=\"wp-image-580604\" srcset=\"https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/workflowdiagram-1024x109.png 1024w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/workflowdiagram-300x32.png 300w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/workflowdiagram-768x82.png 768w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/workflowdiagram-1536x164.png 1536w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/workflowdiagram-2048x219.png 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n<h3 class=\"wp-block-heading\" id=\"h-phase-1-scan\">Phase 1 &#8211; Scan<\/h3>\n\n<p>Using a Leica RTC360 laser scanner, LandTech captured each site at 2mm accuracy, with the added benefit of 360-degree imagery. The scanner\u2019s speed, just one to two minutes per scan, enabled the team to complete the main treatment plant in a week, while both smaller stations were scanned in less than a day.<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-phase-2-model\">Phase 2 &#8211; Model<\/h3>\n\n<p>The scan data was converted into highly accurate 3D models. Water process devices were modeled at <strong>Level of Development (LOD) 350<\/strong>, providing detail sufficient for precise identification and operational context. Structural elements were modeled at <strong>LOD 200<\/strong>, balancing accuracy with efficiency.<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-phase-3-gis-conversion\">Phase 3 &#8211; GIS Conversion<\/h3>\n\n<p>The models were transformed into GIS-ready formats, including building scene layer packages, web scene layers, and derivative 3D point features. A critical step in this phase was Pennichuck staff participation in <strong>asset identification within the models<\/strong>, a painstaking but essential process that enabled interactivity and ensured the GIS environment reflected real-world conditions.<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-phase-4-app-configuration\">Phase 4 &#8211; App Configuration<\/h3>\n\n<p>The interactive models were deployed through a <strong>browser-based application<\/strong> built with ArcGIS Experience Builder. Customization leveraged <strong>ArcGIS<\/strong> <strong>Arcade expressions<\/strong> and Python scripts to create a seamless experience. Staff could explore facilities in 3D, visualize inspections and work orders directly in the scene, and launch into existing systems with a single click\u2014including linking to <strong>mobile applications<\/strong> for work order management.<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-phase-5-system-integration\">Phase 5 &#8211; System Integration<\/h3>\n\n<p>Data integration was designed to maximize visibility and ease of use while minimizing complexity. Asset management data was connected via web services, operational data was integrated through APIs, and deep links enabled smooth navigation between applications. Python routines supported real-time and historical data polling, writing results into hosted tables for use within the app.<\/p>\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"490\" src=\"https:\/\/www.esri.com\/en-us\/industries\/blog\/wp-content\/uploads\/2025\/12\/ExB-Screenshot2-1024x490.png\" alt=\"\" class=\"wp-image-580605\" srcset=\"https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/ExB-Screenshot2-1024x490.png 1024w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/ExB-Screenshot2-300x144.png 300w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/ExB-Screenshot2-768x368.png 768w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/ExB-Screenshot2-1536x735.png 1536w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/ExB-Screenshot2.png 1918w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Screenshot of ArcGIS Experience Builder Application with Interactive 3D Scene, Asset Data, and List of Work Orders<\/figcaption><\/figure>\n\n<h2 class=\"wp-block-heading\" id=\"h-staff-reaction\">Staff Reaction<\/h2>\n\n<p>The response from staff was immediate.
