Portland International Airport

Portland International Reduces Water Usage By 177,000 Gallons Daily
Major facilities are particularly under pressure to make water efficiency a priority because of the massive amount of water their occupants use daily. This has been true of Portland International Airport, which tracked a record 14.6 million passengers in 2007 in the environmentally conscious Oregon city.

"With more than 35,000 people using our facility daily, we recognize that water is a very important resource for which we’re always looking for ways to conserve and protect," says Phil Ralston, aviation environmental and safety manager for the Port of Portland.

The toilets were an obvious target for water savings. The terminal’s 400 toilets, averaging 200 flushes apiece per day, used 3.5 gallons of water per flush. Collectively, the totals were staggering: The toilets’ 80,000 flushes consumed 280,000 gallons of water every day.

The Port of Portland installed UPPERCUT® dual-flush Flushometers from Sloan Valve Company in all of the terminal restrooms and realized immediate and significant results. By replacing the 3.5 gpf toilets with the dual-flush Flushometers, which use 1.1 gallons when the flush valve handle is raised and the standard 1.6 gallons when the handle is pushed down, the airport is only using an average of 103,000 gallons of water daily. That equates to a savings of 177,000 gallons through this one basic plumbing change.

Restrooms in the Port of Portland executive offices underwent water-efficient plumbing upgrades as well with the installation of Sloan ECOS® electronic dual-flush Flushometers.

The Sloan ECOS Flushometers offer the same water savings as the UPPERCUT models with a major added advantage: Restroom users can either press a button to select the appropriate water-saving flush cycle, or they can simply walk away and allow the Flushometer to automatically initiate a reduced or regular flush. The Sloan ECOS' Smart Sense Technology&trd; selects the correct flush cycle based on how long the user remains in sensor range.

"By installing the flush valves, we’ve been able to recognize real water savings and have a positive impact environmentally and on our business’ bottom line," says Larry Medearis, senior manager of aviation maintenance and facility services. "In tight economic times, we're looking to save anywhere and everywhere we can."

Ensuring passenger comfort is important to the airport, which Condé Nast Traveler magazine recently named as the best airport in the U.S. for the third consecutive year in its annual poll of business travelers. And when installing convenient-to-use, dual-flush Flushometers also drastically reduces water usage, it simply makes good sense.

By installing the flush valves, we’ve been able to recognize real water savings and have a positive impact environmentally and on our business’ bottom line. In tight economic times, we're looking to save anywhere and everywhere we can.
