NEWS RELEASE 08/08/13: Portland Water Bureau Ends Groundwater Maintenance Operation

At 3:00 pm today, August 8, 2013, the Portland Water Bureau will complete its maintenance operation that blended a small portion - about 3 percent - of water from its Columbia South Shore Well Field into the water distribution system. Portland's well fields are located in outer Northeast Portland, near Gresham.

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 help ensures the reliability of the system when needed, either in an emergency, or to meet seasonal supply demands.
