DESCRIPTION
Washington State’s response is the Puget Sound Initiative – an action plan to protect and restore the environmental health of Puget Sound and Hood Canal. Parks decided to employ membrane bioreactor (MBR) technology in part to increase the level of wastewater treatment for the selected parks. MBRs were also selected for their ability to minimize site footprint requirements on park property and provide the capability for remote facility operations, nutrient removal, and the opportunity for reuse of the effluent. Ft. Flagler State Park Utilities Improvements & MBR Project was chosen as Water & Wastes Digest Top Projects Award. The Fort Flagler plant has been in operation since June 2009.
