Loudoun Water's Digital Transformation: Improving Asset Management

Located in Northern Virginia near Washington, D.C., Loudoun Water provides drinking water and wastewater services to more than 80,000 households in one of the nation's fastest-growing counties.

Loudoun Water maintains over 1,200 miles of water distribution pipelines, more than 900 miles of wastewater collection system pipelines and a growing reclaimed non-potable water system. To keep pace with increasing demands, Loudoun Water decided to improve its process for handling asset management and field service work orders.


Since implementing the SAP enterprise resource planning (ERP) software and it’s mapping technology, Geo.e, Loudoun Water has worked to deliver the benefits of an integrated geospatial solution to its 150+ operations staff working in the field and at facilities/plants. The main challenge was to simplify the management of daily workloads and eliminate the cumbersome, labor-intensive paper-based processes.  To meet growing demands, Loudoun Water decided to enhance its asset maintenance and field service work order management processes.


Loudoun Water determined that Trimble Unity’s mobile and GIS-based SaaS platform approach was the right solution to solve its immediate need for improving field operations and mobile work management. Trimble Unity met the requirements for an offline-capable, map-centric work order management solution that integrates with Loudoun Water’s existing SAP ERP and Esri GIS systems, and runs on multiple mobile platforms (Windows 10 and iOS). Field staff loved that it put their work and the GIS together in a single user-friendly window; IT liked that it was cloud-hosted and leveraged existing SAP/Esri investments.

Loudoun Water’s project to roll out Trimble Unity was broken into two phases. The first phase was on a hard deadline and needed to be completed in time for the utility’s annual Spring hydrant flushing program. A Trimble Unity app was configured and deployed to meet that schedule and used to generate more than 20,000 orders while tracking the work. Field technicians used a simple iPad app to spatially visualize hydrant flushing assignments, progress each through the configured workflow, capture all required information, and track progress.

The second phase involved implementing multiple apps, each optimized to streamline a specific business process. These Trimble Unity apps named “My Orders”, “Report It” and “Fix It”, include the capability to manage truck and crew assignments, manage and complete SAP-generated work orders and service orders, create SAP notifications to report assets needing repair, record repairs, and track inventory, labor and material usage.

For in-plant assets, Trimble Unity provides users with multiple ways to access SAP functional locations and equipment, enabling operators to browse and search the asset hierarchy when creating work orders or notifications. Trimble Unity offers comprehensive access to assets displayed in GIS, and for in-plant assets like pumps and controls, operators can search or drill down through the asset hierarchy to record repairs or create notifications.


The deployment of Trimble Unity has replaced labor-intensive, paper-based processes with a streamlined digital workflow, allowing Loudoun Water's 150+ field staff to easily manage their daily workload. This digital transformation enables end-users to record data directly in SAP and provides management with real-time access to results.

Utility work crews now have access to up-to-date GIS maps, SAP work orders, and data on their iPads and Windows tablets in the field, allowing them to efficiently manage their daily tasks and interact with the back-office SAP system through a user-friendly mobile application. With Trimble Unity, Loudoun Water leverages its existing investments in SAP and Esri GIS, extending these technologies to the field via a cloud-hosted solution, thus avoiding the additional costs and resources associated with traditional in-house IT infrastructure.
