Improvements to Portland’s Water Supply

We are making two important improvements to Portland’s water supply from Bull Run. Both projects are required under state and federal law. The first project, Improved Corrosion Control Treatment will further adjust the chemistry of Portland’s water, reducing potential levels of lead at the tap. Improved corrosion control will be in place by 2022. The second project, the Bull Run Filtration Plant will remove the microorganism Cryptosporidium and other potential contaminants. The new filtration plant will be in operation by 2027. Both projects will help keep our water safe and abundant for generations to come.
