NEWS RELEASE 07/09/14: Portland Water Bureau Returns to 100 Percent Bull Run Water

By Lindsay Wochnick

This afternoon, July 9, 2014, the Portland Water Bureau returned to 100 percent Bull Run water after completing its maintenance operation that blended a small portion of water from its Columbia South Shore Well Field into the water distribution system. 

On June 30, the Portland Water Bureau detected a leak on one of the supply conduits from the Bull Run. The conduit was taken out of service to repair the leak, requiring the Portland Water Bureau to augment the Bull Run supply with drinking water from the Columbia South Shore Well Field. While using groundwater, the bureau took the opportunity to perform its annual maintenance operation of the groundwater system from July 7 to July 9. This replaces the maintenance run scheduled for August 2014. 

The routine maintenance is required due to the groundwater supply’s complex system composed of electric pumps, chemical feed systems, electronic controls and other equipment that must be operated regularly to identify maintenance needs. By doing this operation routinely, the bureau ensures the reliability of the system when needed, either in an emergency or to meet seasonal supply demands. 

It will take about 24 to 60 hours depending on your location for Bull Run water to move through the distribution system and reach you. Both sources of water are high quality water supplies which meet or surpass all federal and state drinking water regulations.
