Scope Of Work

The Potomac Pumping Station Rehab Phase 3 was one of the most challenging projects ACE has encountered. This project was located at a massive 460 MGD pump station and required the phased replacement of major equipment in the basement and wet wells of the pump station. Equipment to be replaced included eight each 54" cast iron motor operated gate valves, four each 35' tall mechanical bar screens, and fourteen each large stainless steel motor-operated sluice gates, along with supporting electrical and control equipment. There was no crane access to the work areas so all hoisting had to be custom engineered and constructed in place. This job required the most complicated and difficult rigging that ACE has had to perform.
