Portland, Oregon – The Sunrise Water Authority, in cooperation with the North Clackamas County Water Commission, recently broke ground on one of the Pacific Northwest’s first US Filter/Memcor submerged membrane water treatment facilities. The new $13.5 million fast-track facility incorporates low pressure submerged membrane technology designed to effectively treat Clackamas River water and increase the water supply to several communities in the Portland area.
The facility includes a 15-mgd capacity microfiltration water treatment plant housed in a 9,300 square foot building, a powdered activated carbon feed system for taste and odor control, drying beds for solids handling as well as links to existing raw water and treated water pump stations. The filtration building will house all of the ancillary facilities to the membrane operation as well as a new control room, maintenance area and chemical feed facilities.
The expanded facility, designed by MWH, creates a unique combination of old and new water treatment technologies. The new microfiltration plant will operate in parallel with an existing 10-mgd slow sand filter plant placing the oldest and newest in drinking water filtration technology side by side on the same site.
MWH’s fast track approach to design and construction shortened the overall schedule by nearly a year, with an estimated completion of the new facility by Summer 2005, just 17 months after notice to proceed with design.
