According to https://thewaterproject.org/water-crisis/water-in-crisis-ethiopia, Ethiopia is located in Africa's Horn where drought and politics are two leading causes of water shortage. In a study conducted by Water.org, they found that "42% of the population has access to clean water supply" and only "11% of that number has access to adequate sanitation services". In rural areas of the country, these figures drop even lower, resulting in health problems in the villagers as well as their animals. There is a lack of water in Ethiopia and the Horn of Africa. There can be many reasons but the most common one is wastage. This design solves the major water wastage of car wash service. As seen in the attached pictures, the common car washing mechanism has a very high amount of water wastage in Ethiopia. I took the picture in the capital city of Ethiopia, Addis Ababa near my area of residency. The car wash uses drinking water to clean cars as seen in the picture. And it is common water will not be available from time to time in the capital. This is a major issue and it needs to be dealt with.
The objective of the design is to build a containerized car wash mechanism that captures water for re-use, is cheap and easy to deliver and set up, and is quick to manufacture and uses solar power to run the system. This means reusing the water that is discharged from washing the vehicle. In our country water shortage is common but you do not see water preservation mechanism. And car wash service provider consumes a large amount of drinking water for their business while the society lucks regular supply of drinking water. So my invention makes car service providers self-sufficient and saves the life of society by ensuring their supply of drinking water. The mechanism contains a closed structure, water pump, gate valve, non-return valve, sand filter, reservoir, pipe, solar system, hose, and bar screen. The car enters into the container for trapping the waste car. Then dirty water passes through bar screen for trapping slugs. Then by using a pump the water is forced to go to sand filter, it can not be drinkable after filtration but we can wash the car with it. Then finally the filtered water is directed to the tank and to washing hose by using a small pump. Car wash mechanism has 3 phases, prewashing, detergent washing and finishing. The prewashing and finishing water can be easily filtered by the sand filter and can be used only for prewashing and finishing. since the sand filter does not filter the detergent we separately filter the detergent washing.

I have dedicated my life for invention and research because not only I have big dreams but also it is my only way out of poverty. We all have a talent we know or did not find out yet. Mine happens to be inventing. I discovered this talent of mine when I was in second year student during my university life. Starting from that point everything seemed not important except creating new ideas. So, until now I have invented more than 50 inventions which are new to the world and the rest are intended for Ethiopia that will change the life of many people including mine. But because of poverty, theft and many reasons I could not manage to make it. But all that matter is I will never give up. I will invent until and after I become successful. That makes me a strong entrepreneur. My skills are aided with a mechanical engineering degree on design, production and sales expertise.
