Portland is building a new filtration facility to keep our drinking water safe and abundant for generations to come. Filtration will remove the microorganism Cryptosporidium from the Bull Run supply and must be completed by September 2027 to comply with state and federal water quality regulations.

The improved treatment facilities were completed in April 2022 to help make water from the Bull Run less corrosive to lead and other metals found in some home and building plumbing.

The City of Portland has committed $4 million for maintenance, repair, and preservation work at the Mount Tabor Reservoirs. While the three open reservoirs at Mount Tabor no longer supply drinking water, they continue to be important assets to the City of Portland.

The Portland Water Bureau is replacing reservoirs that have served the city since 1894 with a new 12.4-million gallon, seismically reinforced underground reservoir.

This project is on pause until 2027. Find more information below.

The Willamette River Crossing Project will build an earthquake-resilient water line deep under the Willamette River. The project will enhance our water system's resilience, ensuring safe and abundant water for generations to come.
