Many assume that this will inevitably lead to "water wars" between needy states.

In 2012, when New Hampshire student Deepika Kurup was thirteen, she witnessed problems caused by tainted water firsthand when she traveled with her family to India. As Karup later explained, “I saw kids being forced to drink water that is too dirty. So dirty, that I wouldn't even touch it.… [This] compelled me to try and address the water crisis.” Kurup was passionate about science and understood that two inexpensive chemicals—titanium oxide and zinc oxide—undergo a chemical change when exposed to sunlight. The chemicals produce molecules that attack and destroy certain types of deadly bacteria found in water

The systems purify two types of waste: graywater, which is wastewater from bathroom sinks, showers, and washing machines; and blackwater, which comes from toilets, kitchen sinks, and dishwashers.

cities such as Phoenix, Las Vegas, and Los Angeles share scarce water supplies with large-scale agricultural regions such as California's San Joaquin Valley. Central California receives only a few inches (centimeters) of rain each year, but with irrigation water imported from the Sierra Mountains and the Colorado River, it has become "America's salad bowl." Much of the produce (lettuce, tomatoes, avocadoes) stocking the grocery store shelves in the United States comes from irrigated fields in the deserts of California and Texas. The Colorado River is so heavily used by the states along its path (Colorado, Utah, Arizona, Nevada, and California) that it contains only a trickle of water where it crosses the Mexican border and it no longer reaches the ocean

argued that the best use of nature was to improve the life of common citizens. Pinchot's ideas were inspired by his observations of environmental destruction and social inequality that resulted from unregulated wilderness exploitation during the 1800s. He was also influenced by the writings of other nineteenth century explorers and naturalists including George Perkins Marsh and John Wesley Powell.

The DPR process begins with water that goes down toilets and drains in homes and businesses. This wastewater, called effluent, is contaminated with human waste, soap, detergents, personal care products, and everything else that flows down the drain. Sewers carry effluent to wastewater treatment plants, where it is filtered and cleaned until it meets sufficient cleanup standards as defined in EPA regulations
