Opportunities for rainwater harvesting

Rainwater can be collected in relatively simple ways. Rain that falls in ditches, on rooftops or on other surface areas is collected in storage facilities such as water tanks or ponds. This water is stored and used for domestic and agricultural purposes. There are also other ways of rainwater harvesting, such as storing it in the ground where it can be used as groundwater for human consumption or for nature. 

The new app demonstrates opportunities for rainwater harvesting. For example, a person in Turkana county in Kenya can enter her location (Kenya, Lodwar), the length and width of the roof of the house (in metres), the number of family members, and the quantity of water used per day. 

The app returns the estimated amount of rainwater that can be harvested, and the quantity of water for a family. It also proposes the size of the rainwater harvesting system as well as its estimated cost.
