LA County Sanitation District has purchased seven Orion weather stations since 2011 – mostly Orion 420s – sited at water reclamation facilities. One of our technicians, Kathryn Hammond, was recently in the area and got a tour of the Whittier Narrows facility. Prior to her visit Kathryn had spoken with Albert Mata on an installation follow-up with this report: “Albert installed the system. Loves it. Was easy to install.” Carlos Alfaro, Supervisor of Treatment Plant Operations, gave Kathryn the tour, including the catwalk over the tank. (Whittier Narrows is an open tank wastewater treatment facility.) Kathryn reports that they use primarily wind speed and direction parameters to help manage for odor based on complaints from the neighbors, as well as the possibility of chemical spills. Using an Allen-Bradley PLC system, the systems is monitored with FactoryTalk software. Learn more about Orion 420 Weather Stations with 4-20 mA Signal Interface

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) Vulnerability Disclosure Program published an Industrial Control Systems (ICS) Advisory on January 6 documenting resolved vulnerabilities of the CWS MicroServer. As part of our ongoing commitment to the reliability, accuracy, and security of our products, Columbia Weather Systems engaged a third-party cybersecurity audit in August 2025 to evaluate the security of the MicroServer . In October 2025, this review identified three vulnerabilities, which CWS disclosed to CISA. Our development team acted quickly to address the findings. All identified issues were remediated and incorporated into MicroServer firmware version MS_4.1_14142. A follow-on assessment by the same third-party confirmed that the remediations were successful. We recommend all customers with a MicroServer update to firmware version MS_4.1_14142. Please contact our support team at support@columbiaweather.com or by phone at 503-629-0887.
