The community where we are working, Nungua,is a costal fishing neighbourhood in the Greater Accra region, Ghana. Though fish is often in good supply, fresh water is not. In order to grow vegetables in the community garden, fresh water is needed. A rainwater harvesting system is essential for the community to have a self-sustaining garden which can independently and economically obtain the water essential for its growth. Here is how the system works:
The collection of rainwater from the roof of a building. The collected water may have debris so it is filtered and then stored for use. The collected rainwater can be used to water gardens and for washing. In some places, the water is sterilized by boiling to be used for cooking and as drinking water (Aquagreen, 2011).
