Project Information

Portland Water Bureau - From forest to faucet, we deliver the best drinking water in the world.

Portland is building a new filtration facility to keep their water safe and abundant for generations to come. The new filtration plant will remove the microorganism Cryptosporidium and must be completed by 2027 to comply with state and federal water quality rules.

The filtration facility will also remove sediment, organic material, and other potential contaminants, providing consistent high-quality drinking water and making the water system more reliable.

Building a filtration facility of this size takes about a decade to plan, design, permit, and construct. The Portland Water Bureau has already begun work on the initial steps and has made some key decisions about the future filtration facility. The new filtration facility will be located just outside the Bull Run Watershed in rural Multnomah County. Portland Water Bureau has owned the filtration facility property for decades and has been operating facilities in the area for more than 100 years. The filtration facility site was selected because it met the requirements—the site is at the right elevation to work with existing infrastructure, it’s owned by Portland Water Bureau, the facility is consistent with the site’s zoning requirements, and it’s large enough to provide a buffer around the facility and its neighbors.
