Building new wells in the Central African Republic is very expensive, something that no village in one of the poorest countries in the world can afford. In close partnership with each village work is initiated before drilling begins, so that villagers take ownership of their wells. The village chooses members for a well committee responsible for cleaning and caring for the well; the committee also raises $200 as a contribution towards their well and participates in selecting the well location. To drill in the Central African Republic, supplies must be shipped over a thousand miles overland on mostly unpaved roads and, in most of the country, drilling must be done through hard granite before finding pure drinking water. Despite all the wells drilled, about 80% of the Central African Republic still does not have access to clean water.
