In the human body, there is 60% – 70% of the water content that flows in the body. This means that water is very important for the human body, because in a day humans can consume food as much as 3-4 times. But for water consumption, humans can consume 8-9 times or as much as 2 liters of water per day.
Unfortunately, we still encounter many crises on clean water in many parts of the world. For example, some parts of Africa, Asia, and America still lack clean water. There are many ways to provide clean water, one example is by channeling springs to areas that are difficult to reach. In fact, the existing springs cannot meet the water needs in the area, because of environmental pollution that contaminates the springs.
Solution after solution has been sought, one of which is to consume rain water. For example, Nigeria is one of the countries in Africa that is included in the category of poor countries. The problem of clean water in Nigeria is chronic, but with the help of technology, Nigeria can slowly overcome the clean water crisis.
The solution to this is to collect rainwater, which is then processed before being distributed to the community. Actually, rain water is not fit for consumption. According to the CDC (Centers for Diseases Control and Prevention), in order for the stored rainwater to be drinkable, it must go through a filtration process, then it must be disinfected and tested regularly. However, the process must be in accordance with the conditions in the area where the rainwater falls.
