According to the Global Health Organisation (WHO), 748 million people lack access to unpolluted clean water supplies. Moreover the WHO estimates that 1.8 billion people use fecally infected drinking water supplies, 2.5 billion lack access to better health facilities, and more than 840,000 people die from water-related diseases per year. Polluted water is the number one cause of death in developed countries, causing diseases like cholera, measles, typhoid fever, malaria, ascariosis, dengue fever and many other devastating diseases.

 In fact, dirty water is the number one public health concern worldwide, according to the WHO, based on its impact on population. Luckily, the WHO estimates that 10 percent of the global disease burden could be eliminated with better water supply and sanitation. With this in mind, a variety of developments and technologies are providing growing solutions to this issue.

Ultraviolet water filtration devices use ultraviolet (UV) radiation to kill toxic bacteria in drinking water, such as the Camelbak 25 Ounce All Clear Container and the UV Waterworks systems. The filtration of UV light is highly efficient, removing up to 99.9 percent of harmful water microorganisms. The Camelbak Bottle has many benefits, including fast filtration, convenient portability, and ease of use it takes only one minute to deliver clean water). Additionally, the UV lamp inside the Camelbak lasts for 10,000 cycles and provides enough energy for seven years to clean three liters of water.

 Its high cost includes some of the drawbacks of the Camelbak bottle; it could be outside the reach of many consumers at $99, especially in developing countries. In addition, Camelbak purifies drinking water only and is not ideal for the washing of other water, such as boiling water. It has restricted uses for sanitation, too.The benefit of UV waterworks is that they can purify up to four gallons of water per minute, which is enough drinking water for nearly 2000 people. Its only downside lies in the fact that electricity or another power source, such as a car battery or solar cell, is needed to operate.
