Washington Park Reservoir Project
Portland Water Bureau, Hoffman, PBOT make fresh water source safe, secure
Portland residents have a new source of fresh water this year thanks to the $200 million Washington Park reservoir project. Hoffman Construction Co. built the 12.4-million-gallon project for the Portland Water Bureau.
Washington Park’s water infrastructure was built more than 120 years ago. The need for better safety and security, as well as seismic resilience, led the city to make the improvements. The new enclosed, concrete box is anchored to bedrock with dozens of reinforced pilings up to 5-feet thick. The reservoir is engineered to withstand a magnitude 9 earthquake.
Replacement Washington Park reservoir project reaches milestone December 10 2020
The Portland Water Bureau hosts an online celebration to mark the completion of the $205 million underground reservoir.
The project to replace the water reservoir in Washington Park reached a milestone when the final concrete slab was poured on Monday, Dec. 7.
The new 12.4-million-gallon reservoir is expected to begin providing water to more than 360,000 west side customers in the spring.
The Portland Water Bureau marked the completion with an online celebration that included comments by some of the people most closely involved with the Washington Park Reservoirs Improvement Project. They included Patricia Schechter, wife of the late Commissioner Nick Fish, who oversaw the bureau during much of the project before passing away in January of this year.
