Probleemstelling
The problem we’re trying to solve is no water-access in dry areas in the world. Our solution is a system which filters seawater with sand of the desert.
Oplossing
The seawater gets pumped into the Sahara, where it is sprinkled over the sand. The pumps we use pump the water with a speed of 4,580,400 litres/hour. The water flows into the ground and gets filtered. There are layers of sand, charcoal (which may be already used in barbecues) and gravel which work as a natural filtration system. There are pvc wall panels, made from onland and onshore plastic soup from Africa, in the ground to prevent the water flowing too deep. Eventually the salt of the seawater will form a clot in the sand. We are going to dig it out every quarter of a year and sell it to polar regions for the defrosting of roads. Vegetation in the desert prevents the water from evaporating. We are going to plant aloë vera (which can be used for products like: beauty products etc.) and tomato, potato and strawberry plants which are salt tolerant. They can handle large amounts of drought and can grow on salt soil.
The advantage of this system is that it can work in a lot of places such as Africa (Sahara) or also in Asia (Thar desert). This system is easy but solves a lot.
