Water pressure is back A problem last week at Seaside's water treatment plant that kept it from producing much water has been resolved, Seaside City Manager Mark Winstanley said today. Algae had "gummed up the filters," Winstanley said, causing the plant to backwash every three or four hours instead of the usual 16 to 24 hours.
"Algae tends to bloom very quickly," Winstanley explained. "One day you aren't having any problems - the next day you are." He said relatively warm and sunny conditions led to the sudden algae bloom.
Seaside residents were asked to conserve water over the weekend, and the cities of Gearhart and Warrenton gave permission to open the 10-inch intertie connection at the north end of Seaside. That influx of water helped get Seaside's North Reservoir back its normal level, which stabilized the water supply and pressure within the system.
Winstanley emphasized that what happened was not a water supply issue, but a processing problem at the plant. To address the problem, he said some procedures for cleaning out the filters have been changed.
