The Portland Water Bureau returned to 100 percent Bull Run water today, Oct. 17. On June 19, the Portland Water Bureau began blending a portion of water from wells at the Columbia South Shore Well Field to augment supply from the Bull Run. Between an anticipated return of fall weather and lower seasonal demand, Bull Run reservoirs have adequate supply to meet Portland’s drinking water needs. 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.
Through careful planning and investment, Portland has developed two excellent water sources that ensured the City could meet all of its customers’ needs through this warm and dry summer. Together, the Bull Run watershed and the Columbia South Shore Well Field constitute a resilient drinking water supply.
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 when it activates and discontinues use of groundwater.
