O’Hare Airport Storm Water Basin Pumping Stations

Chicago Department of Aviation


To provide and maintain reliable SCADA control and monitoring of three storm water pumping stations and their associated remote sites. Storm water runoff from O’Hare needed collection, oil/water separation, and pumping into the Chicago Water Reclamation District’s sewer system. The detention basins at O’Hare are rather large, the south basin alone has a maximum storage volume of 1,185 acre-feet and covers approximately 115 acres.


Since since the 2007 O’Hare Modernization Program, as a SCADA integration subcontractor, Allan ICS has been providing much of the original instrumentation and controls for waste water management requirements. Various projects included control panels, programming, and equipment upgrades under Siemens, which is O’Hare’s on-site building technologies general contractor.

We continue to provide maintenance and improvements for the North, South, and Central Detention Basin Pump Stations and telemetry to their associated water reclamation district sites. We provided equipment to interface with the switchgear, VFD’s, MCC’s, gate and valve actuators, level and flow transmitters, gas detection, HVAC, and other vital systems.

Integration Details

Major components include Allen-Bradley ControlLogix and MicroLogix PLC’s and PanelView Plus HMI’s along with Data-Linc leased-line modems. Communication protocols used include Ethernet/IP, DF1, and Modbus through copper, fiber, and phone line.
