Scenarios+and+Requirements

Many rural areas of sub-Saharan Africa lacks proper functioning water systems. The lack of available clean water creates many social problems such as health and education. The fact that many people have to journey long distances to acquire fresh water creates the need for alternative methods to obtain water. Rainwater is somewhat abundant in many parts of sub-Saharan Africa but most if not all homes lack the proper equipment to effectively capture rainwater for usage. If an effective and economical rainwater harvesting system can be equipped, then there would be less burden to acquire fresh and clean water in many water lacking communities.

 * __ Scenario 1 __**

=
Our target location- the sub-Saharan Africa has extreme amount of rainfall during the year. In the area where the weather is tropical wet and dry, the amount of rainfall is not consistent throughout the year. In winter months, sub-Saharan Africa experiences dry season. During winter, the area receive very little amount of rainfall. This leads to droughts at this period of time. Water shortage becomes a serious problem that the residences have to face during the winter. Moreover, the tropical wet and dry climate also cause the amount of rainfall becomes irregular from one year to the next. As a result, sub-Saharan Africa would experience floods this year and droughts next year.======

=
In sub-Saharan Africa where excess rainfall occurs in summer months or a certain year, the massive reproduction of mosquitoes cause by wet conditions can affect the health of the people. It is because the life-threatening disease named Malaria is transmitted by bites of infected mosquitoes. Malaria is caused by parasites that reproduces fast in wet condition. According to World Health Organization, most cases and deaths are in sub-Saharan Africa. A child dies every thirty seconds because of Malaria in sub-Saharan Africa. Malaria also causes nearly one million deaths every year. Since Malaria is preventable, the problem of water condition is needed to be fixed so that the reproduction of mosquitoes can be eliminated and thus decreases the cases of Malaria.======
