Overview

The Water Bureau has replaced its original 1894 reservoirs with a new 12.4-million-gallon, seismically reinforced underground reservoir. This reservoir supplies water to Portland's west side and serves more than 360,000 people, including all downtown businesses and residents, 20 schools, 5 hospital complexes, and more than 60 parks.

Currently we are working to install the reflecting pool and interpretive elements, restore historic structures and open the area to the public for the first time in decades.

Stay tuned for a grand opening celebration in spring of 2025!
