Drinking Water Quality at Home

Ensuring the delivery of high quality water is a shared responsibility between the Portland Water Bureau and our customers. The Water Bureau monitors and maintains the drinking water system up to and including the water meter. Beyond the water meter and into the house is the responsibility of the customer.

The Portland Water Bureau’s Water Line is dedicated to helping our customers with any concerns or questions regarding water quality issues. This includes, but is not limited to, water quality and pressure complaints and inquiries, and managing customer lead-in-water and metals test results. The Water Line staff can help customers troubleshoot water quality issues in the home and can coordinate with other Water Bureau departments to address customer concerns.


The Water Line operates Monday through Friday from 8:30 am to 4:30 pm and can be reached at 503-823-7525 or
