Chicago's Deep Tunnel Project Completed with the Help of Sorensen Systems

A recent project that we, at Sorensen Systems, were called upon for our engineering and fabrication capabilities was the Chicago Deep Tunnel. This project, also known as the Deep Tunnel Project, was established to decrease flooding in the Chicago area and to reduce other harmful effects of flushing raw sewage into Lake Michigan. The solution involved diverting storm water and sewage into large, deep tunnels and vast holding reservoirs.

Our roll in this project was to engineer and build a hydraulic and automation motion control system to operate a massive water control gate at the 300 foot deep Thornton Quarry Reservoir. The gates regulate the flow of water through large underground tunnels constructed to slowly feed the stored water to the Calumet Treatment Facility before being released into the Cal Sag Channel. The four stainless steel roller gates, manufactured by Steel-Fab, Inc., are powered by Sorensen Systems Hydraulic Power Units.

“We are happy to put our latest engineering marvel to work. The Thornton Composite Reservoir is the world’s largest reservoir and has drawn intrigue from across the world.” – Spokesperson for the MWRD

According to information released by the MWRD, over 500,000 people benefit directly from the protection to over 180,000 homes in the 14 communities to the south of Chicago.
