The Portland Water Bureau returned to 100 percent Bull Run water today, Aug. 27. Since July 10, the Portland Water Bureau has been supplementing the Bull Run supply with groundwater from the Columbia South Shore Well Field. Proactive supply management along with a mild summer have allowed a return to the Bull Run reservoirs as the sole water supply source. 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 long, warm and dry summer. Together, the Bull Run watershed and the Columbia South Shore Well Field constitute a resilient drinking water supply.
It may take up to two weeks, depending on location, for 100 percent Bull Run water to move through the distribution system and reach customers.
