Water
As a major operator of resorts, many of which are in the desert destination of Las Vegas, we understand the importance of water as a critical resource. We are committed to water efficiency and driving down consumptive use. In 2022, MGM Resorts President and CEO Bill Hornbuckle endorsed the CEO Water Mandate, a UN Global Compact initiative encouraging business leaders to advance water stewardship. MGM Resorts was one of approximately 250 endorsing companies, the first gaming company and the first Las Vegas-based company to make the commitment. With this endorsement, MGM Resorts commits to action and continuous improvement across six elements of water conservation.
Water Strategy
As part of our journey toward corporate water leadership, we developed a water whitepaper, a data-driven and stakeholder-informed piece that helped us understand the condition of water in jurisdictions where MGM Resorts operates. This work, guided the creation of our Global Water Policy and a strategic framework for water stewardship with five key pillars, including water measurement, water efficiency, water quality, water citizenship and water culture. This work underscores our commitment to being a leader in advancing responsible water management across the Colorado River Basin.
Water Efficient Operations
We’ve saved more than 17 billion gallons of water since 2007 through extensive installation of low-flow and touchless fixtures across new and existing properties. Ongoing upkeep through our Zone Maintenance Program ensures optimal performance and prevents leaks. At MGM National Harbor, a 700,000-gallon cistern captures and reuses rainwater for cooling and other needs, reducing reliance on municipal sources.
Water Recycling
At MGM Resorts, we design and develop with water recycling in mind, diversifying sources and reducing future demand. In Southern Nevada, nearly all water returned to the drain is recycled and in Las Vegas, more than 75% of our water use is returned to Lake Mead for reuse. The Fountains of Bellagio use an onsite well and pool water from the 'O’ Theater' as source water, avoiding reliance on water from Lake Mead, saving an equivalent of 3.3 million gallons of water annually. More than 90% of the water of the Shark Reef Aquarium at Mandalay Bay is reused.
Water Efficient Evaporative Systems
The landscapes at our resorts are designed with water efficiency in mind. We’ve removed over 250,000 square feet of grass, replacing it with artificial turf and drought-tolerant plants—making all Las Vegas Strip properties grass-free. Our horticulture programs also prioritize native and adapted plants to further reduce irrigation needs.

Water Efficient Evaporative Systems
Cooling towers are one of our most water-intensive systems. By upgrading to advanced models and doubling efficiency in Las Vegas, we’re saving up to 50% more water. At Bellagio, a first-of-its-kind hybrid cooling tower will save 19 million gallons annually.

Water Citizenship
At MGM Resorts, we build innovative partnerships to advance water stewardship nationwide. In 2024, we committed $500,000 to the Southern Nevada Water Authority Water Innovation Fund to support enhanced residential water conservation rebates for our 50,000+ employees in Southern Nevada. Partnering with the Las Vegas Grand Prix, we also installed an atmospheric water generator at MGM Grand, capturing cooling tower plumes to produce non-local water for track preparation. By mid-2025, it had generated nearly 400,000 gallons of water.

Water Culture
We are committed to increasing employee awareness of water issues. The MGM Planet Protectors is a business resource group (BRG) with a vision that every employee can be an environmental champion through environmental education and volunteerism. Regular activities build an educational foundation of environmental sustainability, provide a forum for involvement in environmental initiatives and create a network of environmental champions across the company. Guest engagement on water includes linen and towel reuse and in-room messaging of positive environmental behaviors.
