Fanno Basin Pressure Line Project

Updated September 20,2017

The Fanno Pressure Sewer Improvement Project has replaced nine of the 19 maintenance access structures planned for replacement in nine locations in the Garden Home are. The project has also installed a pressure monitoring and recording system station near SW Railroad Street. These upgrades will ensure that the Fanno Basin Sewer System will continue to handle all wastewater flows year-round and provide better monitoring of the entire sewer system in the area. The project will protect public health and the health of the Fanno Creek Watershed.

 Developments of Note

  • The second pipeline has work happening at all nine locations.
  • All sites should have the maintenance access structures replaced and be ready for testing by mid-October.
  • Following testing, the pipeline will be drained during the last week of October and all excavated sites will be filled in.
  • The final phase of the project is surface restoration at all sites, including next to the SW 86th Pump Station off SW 84th. This should take place in November.

What We've Heard from You

Neighbors called with concerns last week that the Fanno Creek Trail was closed without any notice received. The closure at SW 86th Avenue was not related to the Fanno Pressure Sewer project and was a paving project by the Tualatin Hills Parks and Recreation District. The trail should remain open for the remainder of the Fanno Pressure Sewer project, except for a short closure during surface restoration. An email notice will be sent when the date is set.
