This image displays a process control system interface for the Canyon Advanced Wastewater Treatment Plant located in Yellowstone National Park. The screen shows a main menu dated May 20, 2026, with a current time of 5:20 PM. The interface features an analog clock at the top and a map of Wyoming identifying the plant location. Below the map is a matrix of operational controls and monitoring buttons organized by functional area, including sections for blower building operations, aerator lagoons 1-3, influent flow monitoring, treatment process controls, sludge management, chemical feed systems, and alarm management. Specific monitoring options include graphical displays for influent flow, filter differential pressure, and nitrification/denitrification tank units, along with dedicated panels for process set points, plant control overview, headworks information, backwash controls, and alarm display functions. This appears to be an automated SCADA (Supervisory Control and Data Acquisition) system interface designed to manage and monitor the wastewater treatment operations at this National Park facility.
