How Seattle’s Climate Pledge Arena is conserving water

700+ water closets, urinals, flushometers, and faucets combine to save water at the 18,300-person venue.

Since it opened in 2021, Seattle’s Climate Pledge Arena has set a goal to be the most progressive, responsible, and sustainable arena in the world.

As the home of the NHL’s Seattle Kraken and the WNBA’s Seattle Storm, Climate Pledge Arena can host up to 18,300 people. With that volume of visitors, even the smallest amount of water conservation per restroom fixture can go a long way.

The venue—sponsored by Amazon—has joined over 375 other corporations in taking the Climate Pledge, an agreement to reach net-zero annual carbon emissions by 2040.

The arena is creating the first International Living Future Institute-certified zero-carbon arena and was the the first arena to announce its intention to eliminate single-use plastic.

When it comes to water conservation, the arena’s “Rain to Rink” system harvests water off its roof, collecting it into a 15,000-gallon cistern and turning it into the greenest ice in the NHL. In addition, on-site retention tanks reduce stormwater runoff.

Sloan commercial restroom fixtures are helping the facility reach its water-saving goals. With over a combined 700 water closets, urinals, flushometers, and faucets throughout the arena, Sloan is giving Climate Pledge Arena a boost with its water conservation efforts.

Climate Pledge Arena specified 45 Sloan SU-7009 Washdown Urinals, along with 110 WES-1000 Water-free Urinals. The WES-1000 uses no water for maximum LEED credits and minimizes water and sewage costs. The washdown urinals are paired with touch-free, high-efficiency Sloan 8186 Exposed Sensor Urinal Flushometers with a 0.125 gpf flush volume to deliver premium water savings.

Sloan’s 329 water-saving water closets throughout the arena are making this vision a reality. These ST-2459 Vitreous China Wall-mounted Water Closets have paired with Sloan G2 8111 Exposed Sensor Flushometers, resulting in low water consumption and high efficiency.

Sloan’s water-efficient products at Climate Pledge Arena extend to the handwashing experience.

Sloan’s Optima EAF-350 Battery-powered Deck-mounted Faucets provide a touch-free and hygiene-friendly experience for all guests, while delivering sustainable flow rates as low as 0.35 gpm.

“Sloan is well-known for its track record of high-quality products, and its performance at Climate Pledge Arena has been no exception,” said Kevin Melsby, Senior Director of Operations, Climate Pledge Arena. “Sloan has brought a high level of forward-thinking in water consumption and sustainability to our facility."
