The Willamette Water Supply Program’s (WWSP) top priority is providing safe, reliable drinking water. Water storage tanks are a critical piece of the water distribution system, providing extra water during peak water use (for example, in the morning when many of us take showers) and water for fighting fires, even during power outages and other emergencies.

WWSP will be constructing two large water storage tanks (15 million gallons each), designed to withstand a large earthquake, on property near the Cooper Mountain Nature Park. Construction is scheduled for late 2021 through 2024.
