Development of water filtration system for the rural areas

D. (a) Problem being addressed
According to Helmer M. (2016) , Water pollution is a global problem, especially in developing regions of Africa. About 70 percent of Earth is covered in water but only 2.5 percent of Earth's water is fresh, drinkable water, and most of that is trapped in ice at the poles or deep underground. That leaves about 0.007 percent of Earth's water available for almost seven billion of us to use for drinking, growing food, providing energy, and producing goods. Even items you might not think about require water to produce. For example, a single pair of blue jeans requires about 3,000 gallons of water to produce because they are made of cotton, and cotton is a water-intensive crop.
Like so many other issues we face today, water shortage is the price we pay for a booming population as well as industrial and technological progress. Because of Africa's environmental, demographic, and economic issues, the region is one of the hardest hit areas of the water crisis, and serves as a warning sign for the rest of the globe.
Like Africa, Many of the third world countries do not have access to clean drinkable water. Water laced with contaminants such as bacteria, viruses, lead, arsenic ,human waste, animal waste, fertilizers, and industrial by-products lead to diarrhea, lethal parasites, and diseases such as typhoid and dysentery that claims millions of lives each year. Children are especially vulnerable to fighting off sanitation-based illnesses, and it is estimated that over half a million children die annually as a result of drinking polluted water. But an inexpensive solution that effectively clears such contaminants from water may help solve this problem.

We want to create a cheap method to help the people living in rural areas by giving them food and make their processed waste as filter systems after eaten.

(c) Specify Requirements
- We want the water to have a pH value of 7
- to be removed of dirt, big particles, toxics and solutions that may lead to cancer
- to be purified and filtered of Cancer-causing molecules.
