Communication breakdowns in industrial systems aren’t just frustrating—they’re costly, disruptive, and often difficult to diagnose.  The Genesee County Drain Commissioner Division of Water & Waste Service (GCDC-WWS) in Michigan struggled with the communication slowdowns in their legacy radio polling system. Poor alarming meant operators could not reliably fine-tune the pumping stations. With 180 remote sites across 600 square miles, these delays became unacceptable. This new case study shows you how they solved the problem.

Texas-based Point Energy Partners (PEP) specializes in acquiring and developing onshore U.S. oil and gas properties with extensive experience working in major basins across the nation. PEP owns and operates the majority of the gathering and midstream assets for its operations, including its very large water recycling program, which showcases their commitment to sustainable and efficient resource management. In an industry where every spill carries a hefty price tag, PEP found that the manual and low-tech systems at their water sites were a significant problem. These sites did not have a big budget for upgrades, so most control solutions on the market just wouldn’t fit the bill.

Sparkplug, the MQTT specification that enhances the way your Opto 22 *groov* systems communicate and operate, has achieved the ISO/IEC 20237:2023 International Standard Status. It’s a significant milestone in the IIoT world, particularly for Opto 22 and our users. As you know, Opto 22 adopted Sparkplug years ago because of its reliability, efficiency, and plug-and-play functionality in modern IIoT architectures. It’s nice to see the rest of the industry accepting and adopting this groundbreaking tech.
