NHL arenas are using water more efficiently in their ice making, food services, plumbing and landscaping. The Staples Center in Los Angeles replaced all 178 conventional urinals with waterless urinals for total annual savings of more than 7 million gallons of water. MTS Centre in Winnipeg uses reverse osmosis to filter water instead of treating it chemically. The water is free of impurities and results in a harder ice surface which requires less maintenance. Amalie Arena in Tampa features an outdoor hydroponic garden which grows fresh produce sold in premium areas. The garden uses a closed system for watering and fertilization, which means all water and nutrients not used by plants or lost in evaporation returns to the tanks below to be used in the next watering.
The League is also working with outside organizations to restore freshwater to rivers and streams in North America. Since 2011, the NHL has restored approximately 50 million gallons of water through its partnership with Bonneville Environmental Foundation. For every fan that pledges to conserve water, the League will restore 1,000 gallons more. Text "NHL" to 77177.
