System in lobby of new airport office building will use a wetland-based process to recycle wastewater for reuse in toilet flushing

Worrell Water Technologies recently announced the next phase of interior construction at the Port of Portland’s new headquarters office facility at the Portland International Airport with the installation of its Living Machine ecological wastewater treatment and water reuse system.
The Living Machine system will be an architectural centerpiece in the lobby of the new office building which is adjacent to the airport terminal building, greeting employees and the public as they enter the building to go to work or attend meetings. Completion of the entire building is set for spring 2010.
The Living Machine system is a proprietary, onsite ecological wastewater treatment approach that produces quality recycled water out of both gray and black water without the chemicals, odor, offensive byproducts or high energy usage required by conventional systems.
As part of its ongoing focus on sustainable practices, the Port decided to build its new offices within a new seven-story parking garage that was already in Port expansion plans, and design the new three-story, 205,000-sq-ft office building as a showcase for sustainable practices.
“The Port of Portland is committed to incorporating sustainable practices in all of our operations,” said Stan Watters, director of development services and information technology at the Port. “We believe that creating a sustainable, environmentally progressive building at the front door of our region helps communicate greater Portland’s green thinking ethic and is simply the right thing to do.
“The Living Machine is truly a centerpiece for the comprehensive green building strategy we have initiated for this entire project,” Watters said. “The Living Machine system is also an important part of our effort to obtain LEED Gold certification for this building.”
The system will treat up to 5,000 gal of wastewater a day to a quality suitable for reuse in toilet flushing and then use UV light to ensure no bacterial contamination before it is pumped back up to the office.
