The World Summit for Children adopted a standardised definition of clean water that has been included in the DCAT-II. The water is considered safe when it comes from an improved source of supply such as: • Taps installed inside or outside the housing; • Standpipes or public taps; • Wells and boreholes with pumps; • Covered or protected wells; and • Bottled water. According to this definition, we see that overall for drinking, 76% of households use water from an improved source, mainly public taps / fountains (27%) and taps in the yard / compound (22%) . The proportion of households whose consumption of water from an improved source shows marked differences according to the place of residence: in rural areas, only 41% from public taps / fountains (40%) than urban households obtain their drinking water, while in rural areas in 22% of cases, the water consumed is from water surface.
