Portland Water Filtration Survey: Tell Us What is Important to You

Take the Bull Run treatment survey

Last August, Portland City Council held a hearing to discuss options for compliance with a federal rule requiring water treatment for the parasite Cryptosporidium. City Council voted unanimously to direct the Water Bureau to begin planning for a water filtration facility.

Since then, the Water Bureau assembled a team that has started work on the planning for the 10-year filtration project.

And now our filtration team wants to hear from you – our customers.

We want to hear what matters to you about the quality of your drinking water and the value to consider in planning the filtration plant.

More About Bull Run Water Treatment

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.
