Services, Guides, and Information

This annual report contains important information about Portland's drinking water and water system.

Located less than thirty miles east of Portland, the Bull Run Watershed's unique geography and rich history make it an iconic part of the story of our region. It serves as the primary drinking water supply for nearly one million people in the Portland metro area.

For over 100 years, Portland water customers have enjoyed high-quality drinking water at their taps. We are prepared to adapt and plan for a warming climate to continue to provide water that's safe and abundant for years to come.

Find Cryptosporidium test results and learn how we're changing our water treatment to address Cryptosporidium. If you have a condition that puts you at greater risk from Cryptosporidium in drinking water, find out how you can reduce your risk.

We test Portland’s drinking water to make sure it meets all state and federal standards. You can see water quality reports and data on this page.

Portland's groundwater improves the reliability of our water system by providing a robust secondary drinking water source that supplements the water we get from Bull Run. Together, these two water sources ensure that we can deliver excellent water every minute of every day.

Just like our rivers, our groundwater must be protected. The cities of Portland, Gresham, and Fairview have implemented the Groundwater Protection Program to protect the Columbia South Shore Well Field, a source of drinking water for nearly one million Oregonians.

Portland has excellent water in part because generations of lawmakers, City staff, and community members have worked to protect Bull Run.

We are committed to reducing our impact on the climate. Here's an overview of the actions we're taking to reduce carbon emissions and become more energy efficient as we continue our essential work of serving drinking water to Portland.

Each year, we develop a Seasonal Water Supply Augmentation and Contingency Plan. This plan makes sure we're prepared for the range of potential drinking water supply and demand conditions that could occur in the Portland area.
