87th Street Lift Station Improvements

​

Overview

• The City’s 87th Street lift station was at the end of its useful life and
   needed to be upgraded

• The existing equipment was original to the station construction with a
   single pump in operation and was over 50 years old

​

Scope​​

• Demolished and disposed of existing lift station equipment. Contractor
   was required to maintain service with bypass pumping while station
   was off line
• Removed a 15-foot deep dry pit and added a new 5-foot deep valve
   vault by adding a minor amount of additional force main
• Installed wet well and valve vault lids with integrated aluminum access
   hatches
• Installed new pumps, pump controls, piping, above grade control
   cabinet, and electrical wiring and gear
• Extensive permitting with the Illinois Environmental Protection Agency,
  Metropolitan Water Reclamation District, and Cook County Department
  of Transportation and Highways

​

Results

​• New valve vault provides City with easy access to valves and piping
• New pump guide rails provide easy removal of pumps and no longer requires
  confined space entry
• Upgraded control equipment and pumps will provide a long service life to the           City
