In the arid landscapes of Nevada, where daily water use tops a staggering 489 million gallons, the urgency for effective water reuse has never been more pressing. 90% of those 489 gallons of water are from the Colorado River. Lake Mead water levels have been dropping significantly, with more than 150 feet of water dropped since the year 2000. Water usage and consumption is a global issue, but it is especially critical in Nevada, a state grappling with a desert climate, rapid population growth, and heavy tourism demands. In this challenging environment, how can we reuse water effectively and efficiently?
There are a lot of campaigns and water efforts towards water consumption in Nevada. You may have seen signs around Las Vegas promoting having shorter showers, using less water, etc. But, have these efforts been working? There’s a whole network of sewage water underneath our floors that are all connected with pipes. This sewage water is transported to a treatment facility, where it is purified repeatedly until deemed clean. The treated water is then released into the Las Vegas Wash, which flows back to Lake Mead. This process provides return flow credits, meaning that for each gallon of wastewater treated, the state can withdraw more water from the Colorado River. This has allowed Nevada to use more water than the 2% of water from the River that it was allocated. Implementing low-flush toilets and shorter showers and recycling every drop of water has allowed Nevada to keep on running. By utilizing these efforts, Nevada has successfully reduced its per capita water usage by 58% compared to 2002 levels (Carson, B. Look at the Future: Will Nevada Run Out of Water?). Considering how the population has grown by 50%, this is very impressive. This means the per-capita water usage is lower than it was in the early 2000s, despite a significant population increase. This system of reusing water from Lake Mead, as respectable as it is, will not be enough for Nevada in the future. As Las Vegas’s population continues to grow and as Lake Mead water levels keep declining, it is only a matter of time until the city faces a serious water crisis. In fact, Nevada made a water shortage declaration in 2021. As climate change gets worse, our temperatures increase and our drought gets worse. In order to fix this, the government has been implementing short-term and long-term plans to fix this issue.
The process of desalination, getting fresh water from salt water is in the process of being used. There are also groundwater recharge strategies and implementing more water treatment are ways the government is planning to help address the water issue. Surprisingly, using less water helps a lot more than you think. Simple actions like turning off the tap while brushing your teeth, taking shorter showers, using low-flush toilets, and running water-efficient dishwashers can all contribute to solving this issue. Bill Gates has also invented a toilet where you can flush without using water or energy. If Las Vegas were to implement Bill Gates’s innovative toilet, which operates without water or energy, it could potentially replace thousands of traditional toilets, particularly in public facilities and new residential developments, thereby reducing the city’s water consumption by millions of gallons annually and making a noticeable impact on its overall water conservation efforts. In addition, this could be helpful if it was implemented in Las Vegas since this toilet can convert feces into fertilizer, clean water, and electricity, which are all resources Las Vegas needs. New machines called omni-processors, can be used to support a fecal sludge treatment plant or complement a waste-water treatment plant. And they require a fraction of the energy, space and cost that a traditional sewer and wastewater treatment plant require.
Although a lot of these methods are expensive, conserving water waste in Las Vegas is very important and necessary as our population grows, especially due to tourism. An example of how tourism depletes water is the Bellagio water fountain, “Yet, water activists often criticize the Bellagio for this man-made lake because it loses nearly 12 million gallons of water per year due to evaporation. With the average household swimming pool holding approximately 20,000 gallons of water, the water lost per year is enough to fill six hundred pools.” (Brutekka, C. A Study of Water Use by Casinos in Las Vegas, Nevada: the Transformation of a Desert into an Oasis). Las Vegas’ drought issue has been a problem for years, and although these efforts have kept Las Vegas running, there’s only a matter of time until it becomes a really serious problem. Spreading awareness and educating ourselves about this water crisis can make a significant difference—not just for individuals but for the entire community of Las Vegas. Together, we can empower each other to take meaningful action in conserving our precious water resources and ensuring a sustainable future for our city.
