The Portland Water Bureau is planning for changes to how Bull Run water is treated.

While water from the Bull Run Watershed is considered some of the cleanest in the nation, it still requires treatment to meet federal standards and protect public health.

Over the next 10 years, the Portland Water Bureau will be making two major treatment changes to the Bull Run.

The first is enhanced corrosion control, which will be in place by April 2022. This will reduce the risk of lead and copper leaching from home plumbing by adjusting the pH, or corrosivity, in the water system. Learn more.   

In addition to enhanced corrosion control, the Portland Water Bureau will be installing a new filtration plant that will remove sediments and organisms such as Cryptosporidium that can cause illness. Learn more.
