The Warka Water Tower

The Warka Water Tower harvests water from the atmosphere. This tower works best in places with high humidity, so dry deserts might not be the best place for installation, however along coastlines where there is a lot of humidity but not a lot of drinkable water might be suitable. The water tower also produces a maximum of 10 to 20 gallons of drinking water per day, so it may only be suitable for small communities, or multiple towers might be necessary. However, the goal of Warka Water is to exclusively use local materials that are natural, biodegradable, and 100% recyclable. It is also designed to be able to be maintained by villagers with whatever tools they have on hand.

The tower works by collecting dew, fog, and rain using a combination of netting on the outside and inside of the structure. The water then falls into a basin below. The basin is protected from evaporation via a canopy. This canopy also allows for people to gather and congregate in a protected area. The design of the tower is based on the Warka tree which grows in Ethiopia, the home of a village known as Dorze, where the first Warka tower was installed. These towers have also been installed in Cameroon, Haiti and Togo.
