The Willamette Water Supply Program is planning to develop an additional source of water from the mid-Willamette River at Wilsonville.

This project will expand the Willamette River Water Treatment Plant and add pipelines and storage to serve Tualatin Valley Water District and Hillsboro Water customers. Other water providers in the region are also looking at their options for future participation.  Take a few minutes to learn more about the Willamette Water Supply Program:
