In Las Vegas, money isn’t the most sought-after resource — water is. With nearby Lake Mead supplying most of the city’s water, the Las Vegas Valley needed to find ways to conserve its most valuable commodity. The Southern Nevada Water Authority developed a ground water management programme to protect and manage the valley’s water supply. As part of the programme, they encourage sites with existing ground water wells to use specific allotments of this underground water to reduce strain on lake usage. Working with Ecolab, one premier resort hotel found an innovative new way to utilize and recycle water from the aquifer, cutting usage by over 57 million gallons in just four years.
