This image displays a supervisory control and data acquisition (SCADA) interface for Aerator Lagoon 2, captured at 5:21 PM on May 20, 2026. The screen shows real-time operational status and monitoring data for four aerators (Aerators 6, 7, 8, and 10) within the lagoon system. Each aerator displays individual control panels with OFF/AUTO/ON toggle buttons and status indicators showing operational modes. Aerator 10 is currently running (green indicator), while Aerator 6 is off (blue indicator), and Aerators 7 and 8 are running (green indicators).

The interface provides critical performance metrics for each aerator, including on-time setpoint in minutes (all reading 0000), on-time elapsed minutes (all reading 0.0), interval setpoint in minutes (all reading 0000), and interval time elapsed minutes (all reading 0.0). Navigation buttons at the bottom of the screen allow operators to access related systems and functions, including Main Menu, Headworks Info, Aerator Overview, Plant Control, Process Overview, Sludge Pumps, Backwash Control, Control Valves, and Alarm Display. Additional accessible subsystems include Blower Building, Aerator Lagoon 1, Aerator Lagoon 2 (current view), Aerator Lagoon 3, and Decant Pumps, indicating this is part of a larger wastewater treatment facility automation system.
