Why is it important to save water?
In the creation myths of many cultures, from ancient Mesopotamia to the book of Genesis, from the Inuit of the frozen north to the Kuba people of the Congo; their stories explain that the world began with formless primordial waters. While science may have a different explanation, we do know that water is important to everyone. All together there is 1.386 billion km3 of surface water or ice, which may already sound like a lot but compared to the size of earth- it is even more significant. Viewed from space, the oceans of our planet cover more than 70% of the Earth’s surface.
Water use has been growing globally at more than twice the rate of population increase in the last century, and an increasing number of regions are reaching the limit at which water services can be sustainably delivered, especially in arid regions. Water scarcity limits access to safe water for drinking and for practising hygiene at home, in schools and in health-care facilities. Scarce water also becomes more expensive. Four billion people, almost two thirds of the world’s population, experience severe water scarcity for at least one month of each year. By 2040 roughly 1 out of 4 children worldwide will be living in countries with extreme water scarcity.
Where does the UAE get water from?
Gulf countries such as the UAE are among nations with some of the highest gaps between water supply. Over 65 % of the world's desalination sector operates in the Gulf countries. The United Arab Emirates alone accounts for 26% of global desalination. Dubai has had to look for alternative sources of freshwater to support its rapid urban development and the increase in population growth. Dubai experiences arid climatic conditions with average summer temperatures of 107 degrees Fahrenheit, which means the emirate does not receive enough rainfall as a natural water source.
Water filtration is the process of removing or reducing any particles, including suspended particles, parasites, algae, bacteria, viruses, and fungi. This process makes the water safe and clean. The filtration systems for drinking water usually have a five-stage filtration process: sediment, mechanical, chemical, mineral, and bacterial. The use of home water filtration has existed for many years in the U.S., where tap water has been assumed to be microbiologically safe to drink.
