Alder Pump Station

Updated March 21, 2019

Environmental Services has completed construction of major upgrades to the Alder Pump Station. The city constructed the pump station at SE Water Avenue and SE Alder Street in 1952. This upgrade project will improve reliability and increase pumping capacity, which will help prevent sewage releases into buildings and streets and combined sewage and stormwater overflows to the Willamette River. For details about the improvements made, click here.

Developments of Note

Environmental Services and its contractor, Stellar J Corporation, began construction of pump station upgrades in August 2017 and completed construction of major upgrades in February 2019.

Other recent developments include the following:

  • The project started up the new pump station at the end of February.
  • The pump station successfully passed a seven-day test.
  • The contractor removed the temporary bypass pumping system in early March.
  • The new pump station has passed final tests and is now in full operation.
  • The contractor has begun demobilization activities, including moving the job trailer off the site and closing the fenced perimeter to just the pump station.

Look-Ahead Schedule

Several lesser tasks remain to close out the project. Environmental Services and the contractor expect to continue working on-site through April to complete these site improvements:

  • Property frontage improvements
  • Drive-through with access from both SE Water Avenue and SE Alder Street
  • Security fencing with gates at each end of the access drive-through
