SW 86th Avenue Pump Station Project

Fanno Creek Recreational Trail closed between SW 90th and SW 86th for reconstruction and repaving from August 24, 2016 to September 21, 2016. Click here for map.


Environmental Services has constructed a new sewage pump station at the end of SW 86th Avenue near the Fanno Pump Station to increase capacity in the pressure sewer system. The added capacity will ensure that the system can handle all wastewater flows during large rain storms. The new pump station will operate year-round. The existing pump station will operate in the winter to manage higher wastewater flows.

The new pump station is now operating and is the primary pump station. The existing Fanno Basin Pump Station is receiving some system updating and become the wet weather pump station as a back up.

Each facility will pump sewage through one of the two new 30-inch steel pipes that are part of the reconstructed pressure sewer system. There will be sections of the pressure line replaced spring/summer 2016, which will cause some closures to the Fanno Creek Trail.

For more information, contact Debbie Caselton at 503-823-2831 or be added to the email notification list.
