NEWS RELEASE 06/29/15: Portland Water Bureau Returns to 100 Percent Bull Run Water

By Lindsay Wochnick

The Portland Water Bureau returned to 100 percent Bull Run water today, June 29, after blending a small portion of water from its Columbia South Shore Well Field into the water distribution system.

The Water Bureau began blending groundwater with Bull Run water on June 11 so scheduled work could be completed to strengthen interties on its largest conduit. This work was completed ahead of schedule, allowing the Water Bureau to return to 100 percent Bull Run sooner than anticipated. While this work occurred, the bureau also took the opportunity to perform its annual maintenance operation of the groundwater system. By routinely doing this operation, the bureau ensures the reliability of the system when needed, either in an emergency or to meet seasonal supply demands.

Due to careful planning, Portland is fortunate to have access to two excellent water sources that allow the City to be prepared to meet the range of supply and demand conditions that could occur this summer. Both the Bull Run and Columbia South Shore Well Field are high-quality water sources that meet or surpass all federal and state drinking water regulations.

It will take one to eight days, depending on location, for 100 percent Bull Run water to move through the distribution system and reach customers.

While public notification is not required, the Water Bureau informs the media and sensitive users, as a practice, when it activates and discontinues use of groundwater.
