Fanno Basin Pressure Line Project

Updated October 6, 2017

This project has replaced all 19 maintenance access structures in nine locations in the Garden Home area, as well as a pressure monitoring and recording system station off 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. It will protect public health and the health of the Fanno Creek Watershed.  

Environmental Services will close a portion of the Tualatin Hills Parks and Recreation Fanno Creek Trail beginning October 23rd through November 10th between SW 81st and 78th avenues and at the Garden Home Recreation Center (see map below) to complete trail restoration.

The remaining six work sites will have surface restoration completed in November.
