The drought that has plagued California and other areas of the western U.S. has not left Las Vegas unscathed, putting the city's primary water resource in jeopardy.
The water levels in Lake Mead, which supplies 90 percent of the city's water, have been steadily decreasing over the past 14 years primarily due to the ongoing drought conditions on the Colorado River.
Currently, the lake's water levels are just below 1,100 feet above sea level and approaching the elevation mark for the first water intake straw, which is one of two that supplies water to the city. The intake sits at an elevation mark of 1,050 feet.
Drought conditions are nothing new for the city, which due to its arid climate averages only about 4 inches of rain per year. Through the first four months of 2014, roughly 0.31 of an inch of rain has fallen in the city and nearly two months have passed without measurable rainfall.
For casino resorts in town, described as the economic engine of the city, water conservation isn't just an option, it's a necessity.
During the early 1990s, resorts were one of the first sectors in the community targeted for conservation.
Any new resort that has been built since then is required to submit a water conservation plan as part of the approval process for construction.
Conservation techniques such as using water efficient technologies, minimizing landscaping, moving water features from outdoors to indoors among other measures are utilized.
"They need to be able to show us how and where they are working to save water," said Bronson Mack, a spokesperson for the Southern Nevada Water Authority (SNWA).
All casino resorts in Las Vegas use roughly 7 percent of the local water resources. However, their actual water consumption is around 3 percent, according to Mack.
"Here in Las Vegas, we have a distinction between what we use, as far as water resources go, and what we consume," Mack said. "Because we recycle nearly 100 percent of our indoor water use."
At the 10 MGM Resorts properties in Las Vegas, they take many steps to be efficient with their water usage, including building and retrofitting many of their operations to be water conservative.
Low-flow shower heads and toilets are installed in their hotel rooms and guests are offered the option to reuse towels, lines and bed sheets each day, according to MGM Resorts Spokesperson Yvette Monet.
The water for the iconic fountains at the Bellagio, does not come from municipal water, Monet said. Rather, it comes from an underground well, fed from its privately owned 8.5-acre lake, which holds 22 million gallons of water.
Annually, about 12 million gallons are replenished due to certain factors such as evaporation and leaky pipes.
Similarly to MGM, Caesars Entertainment has implemented low-flow shower heads and toilets in their hotel properties worldwide, nine of which are in southern Nevada. Caesars also offers the policy of changing sheets and towels in hotel rooms upon request.
The company has tried to move away from water-intensive uses in its Las Vegas properties. With the exception of the fountain outside Caesars Palace, there are minimal exterior water features. Water-intensive landscaping, such as sod, has been converted to desert-style landscaping.
"We're definitely aware of water as an important resource, in trying to implement practices and technologies that ultimately reduce consumptive use," said Eric Dominguez, corporate director of facilities, engineering and utilities at Caesars Entertainment.
Southern Nevada accounts for about 70 percent of the state's economy, according to Mack. The resorts are a huge economic element to the entire state, but they only use a very small amount of the water resources.
"We believe that's a pretty good investment in water," Mack said.
In fact, back in the early '90s, the resort industry helped fund the city's initial residential conservation programs, Mack said.
Due to the fact that indoor water is recycled, Las Vegas has been focusing conversation on outdoor water use. In 2002, the SNWA developed a drought response plan.
Part of the plan includes strict water restrictions for irrigation on residential landscaping. In the winter, watering is limited to one day per week. During spring and fall, residents can water on three days a week, with specific neighborhoods assigned certain days of the week to water their properties.
In the summer, anyone can use water for irrigation any day of the week, so long as it's not between the hours of 11 a.m. and 7 p.m.
Another tactic used by the SNWA is a turf rebate program. Residents are paid to have grass removed and water-efficient landscaping installed. Through the life of the program, about 168 million square feet of grass has been converted.
Construction of a third water intake at Lake Mead began in 2008 in an effort to continue to draw water from the lake, even as levels potentially drop below 1,000 feet, which is where the second intake was built. Set to be complete in 2015, it will help protect municipal water customers from water quality issues as the lake's water levels decline.
While there isn't any reason for panic yet, officials will be closely monitoring the lake's water levels and the construction process of the third intake.
"Our primary concern has been ensuring that we're able to maintain access to the Colorado River and to those water resources," Mack said.
Dominguez said in the U.S., water traditionally has been a utility that's been under-priced and people haven't been as concerned with water use. But he sees a shift in thinking that is beginning to take place in terms of conversation efforts, especially in areas like southern Nevada, where water should be used more smartly.
"It's something that we should be doing not only as an industry, but as a society of people that live here in this type of environment," he said.
