Water: No clear answer
City might need to build another buried reservoir at Powell Butte
Jim Redden • The Portland Tribune • June 19, 2008
At city Commissioner Randy Leonard’s direction, the Portland Water Bureau is drawing up plans to comply with the newest federal clean-water rules.
Unless the bureau can circumvent the rules, the plans could require the city to spend millions of dollars on a new water treatment plant, possibly located at the base of the large reservoir in the Bull Run watershed where Portland gets most of its drinking water.
The bureau also is studying building a second underground 50-million-gallon reservoir at the Powell Butte Nature Park, where one such reservoir already is located.
