Trotter and Associates, Inc. (TAI) continues its partnership with the DuPage County Department of Stormwater Management on the rehabilitation of the West Lobe Pump Station at the Elmhurst Quarry Flood Control Facility. This critical infrastructure serves as a flood control system by storing excess flow during major rain events and later pumping stormwater back to Salt Creek once conditions recede.



Independent Mechanical Industries, Inc., and their subcontractors are on schedule for the West Lobe Pump Station to be returned to service this fall. Over the last several months, the team completed installation of four 500-hp pumps and rehabilitation of the discharge piping supports along the 100-foot quarry highwall. Additionally, the pump station’s electrical system was upgraded with a 2,500-amp switchboard and VFDs to provide a long-term reliable electrical system for the facility.
