But recently, they embarked on a journey to upgrade their legacy global navigation satellite system (GNSS), or GPS, devices.<\/p>\n\n<p>When EMWD enterprise GIS manager Andrea Regalado joined the district eight years ago, just two teams were using the legacy all-in-one GPS receivers: the Recycled Water Group and the Water Operations Group. These older devices required a time-intensive process of loading and unloading files before and after field work. Office staff then needed to post-process the GNSS data and manually import it into ArcGIS. Because technology lacked modern automation and integration features, field crews occasionally had to revisit sites to verify or recapture location data. Upgrading the old devices would improve efficiency and reduce or eliminate site revisits.<a><br><br><\/a>\u201cWith the older GPS units, there were times when we\u2019d need to go back and re-collect certain location points to make sure we had the most complete and accurate record possible,\u201d said Troy Gardner, an on-site field inspector with Golden State Consultants, who help map EMWD\u2019s recycled-water system. \u201cThe new tools eliminate those extra trips and give us confidence in the data from the start.\u201d<\/p>\n\n<h2 class=\"wp-block-heading\" id=\"h-the-solution-real-time-gnss-data-collection-with-arrow-golds-and-arcgis-field-maps\">The Solution: Real-Time GNSS Data Collection with Arrow Golds and ArcGIS Field Maps<\/h2>\n\n<p>EMWD began using Arrow Gold GNSS receivers from Esri partner <a href=\"https:\/\/eos-gnss.com\/\">Eos Positioning Systems<\/a>. They chose the Arrow Golds because of their support for the utility\u2019s existing technologies, such as Esri apps, mobile devices, and an existing base station, and because of the ease of getting technical support.<\/p>\n\n<p>\u201cTechnical support with Eos was spot on,\u201d Regalado said. \u201cWe can call, and our representative is on top of it.\u201d&nbsp;<\/p>\n\n<p>The Arrow Golds provided an average one-centimeter horizontal accuracy throughout the service area. The Arrow Golds provided this accuracy in real time, which eliminated the need for post-processing in the office.<\/p>\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"1024\" src=\"https:\/\/www.esri.com\/en-us\/industries\/blog\/wp-content\/uploads\/2025\/12\/2-20250424_124336-Robert-Toomey-maps-recycled-water-meter-768x1024.jpg\" alt=\"\" class=\"wp-image-580716\" srcset=\"https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/2-20250424_124336-Robert-Toomey-maps-recycled-water-meter-768x1024.jpg 768w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/2-20250424_124336-Robert-Toomey-maps-recycled-water-meter-225x300.jpg 225w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/2-20250424_124336-Robert-Toomey-maps-recycled-water-meter-1152x1536.jpg 1152w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/2-20250424_124336-Robert-Toomey-maps-recycled-water-meter-1536x2048.jpg 1536w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/2-20250424_124336-Robert-Toomey-maps-recycled-water-meter-scaled.jpg 1920w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><figcaption class=\"wp-element-caption\"><em>EMWD consultant inspector Robert Toomey, of Golden State Consultants, maps a recycled-water meter box that was installed as part of a landscaping irrigation development.

They can locate assets and even perform basic analytics (e.g., buffers, queries, filters). If there\u2019s a leak, for instance, EMWD\u2019s Integrated Operations Center (IOC) uses HydroMapper to look up customer addresses, find cross streets, and locate asset numbers.<\/p>\n\n<p>\u201cYou\u2019d be hard pressed to find a department where it isn\u2019t used,\u201d Lee said.<\/p>\n\n<h2 class=\"wp-block-heading\" id=\"h-the-results-accurate-real-time-as-builts-for-the-recycled-water-system\">The Results: Accurate Real-Time As-Builts for the Recycled Water System<\/h2>\n\n<p>Today, the Recycled Water Group is 100 percent powered by Eos and Esri as they capture information about the infrastructure installed in new developments.<\/p>\n\n<p>\u201cWe see the pipes going into the ground right away in the GIS\u2014as accurately as possible,\u201d Golden State Consultants inspector Bobby Toomey said.<\/p>\n\n<p>All as-built information for recycled-water assets is provided in real time with survey-grade accuracy.<\/p>\n\n<p class=\"has-text-align-center\"><strong>\u201cThe amount of processing work we would have to do has gone way down.

In the past five years, they have remapped over 90 percent of EMWD\u2019s valves.<\/p>\n\n<p>Moreover, when a valve lid is no longer visible on the surface of a road, the technicians use the GNSS receivers to navigate back to the valves.<\/p>\n\n<p>\u201cWhen a valve is paved over or covered in dirt, there\u2019s no visible evidence of where it is,\u201d said Brandon Harlacher, a valve technician II at EMWD. \u201cBut now we can get to it. When you take that accurate point, you can just go back to exactly where it\u2019s at, even once it\u2019s paved over.\u201d<\/p>\n\n<p>Accurate valve locations improve shut-off times during incident response. This can translate into less water loss, smaller excavation areas, and fewer minutes that crews need to spend performing traffic procedures to safely enter and exit active construction areas.<\/p>\n\n<p>\u201cYou always want to be able to get to the valve and get out as quickly as possible,\u201d Lee said. \u201cIf that valve is under dirt, asphalt, or water, its precise location is of utmost importance.\u201d<\/p>\n\n<p>The improvements to accuracy have coincided with an even greater demand for geospatial data throughout the water district.<\/p>\n\n<p>\u201cIt seems we are getting more and more people on board using the spatial aspect of our data,\u201d said Janice Nollar-Conrad, an EMWD GIS application developer.<\/p>\n\n<h2 class=\"wp-block-heading\" id=\"h-looking-ahead\">Looking Ahead<\/h2>\n\n<p>EMWD is planning to roll out the same high-accuracy field workflows to their water system and sewer system teams, which don\u2019t yet use survey-grade GPS.<\/p>\n\n<p>\u201cWhat we really want is to roll this out to water and sewer, which are more complex systems,\u201d Regalado said. \u201cOur goal is to be capturing all as-builts with GPS.\u201d<\/p>\n\n<p>EMWD recently purchased three <a href=\"https:\/\/eos-gnss.com\/products\/hardware\/skadi-gold\">Skadi Golds<\/a>, a newer GNSS receiver from Eos Positioning Systems that works similarly to the Arrow Gold but offers additional capabilities, such as tilt compensation and a smart-handle configuration.<\/p>\n\n<p>With <a href=\"https:\/\/eos-gnss.com\/products\/activations\/skadi-tilt-compensation\">Skadi Tilt Compensation<\/a>, EMWD field technicians can capture as-builts without having to level their range poles.<\/p>\n\n<p>\u201cThis speeds up our field units and enhances accuracy,\u201d Regalado said.<\/p>\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"1024\" src=\"https:\/\/www.esri.com\/en-us\/industries\/blog\/wp-content\/uploads\/2025\/12\/4-20250424_130638-EMWD-Robert-Toomey-with-Skadi-GNSS-receiver-and-tilt-compensation-ArcGIS-Field-Maps-copy-768x1024.jpg\" alt=\"\" class=\"wp-image-580731\" style=\"width:840px;height:auto\" srcset=\"https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/4-20250424_130638-EMWD-Robert-Toomey-with-Skadi-GNSS-receiver-and-tilt-compensation-ArcGIS-Field-Maps-copy-768x1024.jpg 768w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/4-20250424_130638-EMWD-Robert-Toomey-with-Skadi-GNSS-receiver-and-tilt-compensation-ArcGIS-Field-Maps-copy-225x300.jpg 225w, https:\/\/www.esri.com\/en-us\/industries\/blog\/app\/uploads\/2025\/12\/4-20250424_130638-EMWD-Robert-Toomey-with-Skadi-GNSS-receiver-and-tilt-compensation-ArcGIS-Field-Maps-copy.jpg 1000w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><figcaption class=\"wp-element-caption\"><em>Toomey maps this recycled water line without having to level his range pole, thanks to Skadi Tilt Compensation.
