Willamette Water Supply Program partners, City of Hillsboro and Tualatin Valley Water District (TVWD), are teaming up with Washington County to construct nearly 2.7 miles of a large-diameter drinking water transmission pipeline in conjunction with the County’s 124th Avenue Extension road project. This is the first section of the more than 30-mile water transmission pipeline to be built as part of the Willamette Water Supply Program.
