	A report in ~~2105~~ stated that 73% of known water systems across Angola use groundwater sources, and that drilled boreholes equipped with hand pumps represented 36% of all water supply systems (Cowater 2015). The use of groundwater varies across the country, with some provinces obtaining over 90% of their water supplies from groundwater, but most obtaining between 40% and 80% of water supplies from groundwater. Only three provinces obtain less than 20% of water supplies from groundwater (Cowater 2015).

Only three provinces obtain less than 20% of water supplies from groundwater (Cowater 2015).

	The provincial capitals of Malange, Bengucia, Lubango and Namibe, and the urban centres of Tobwa and Lobito, rely on groundwater to a greater or lesser extent. In general, groundwater use in urban areas is concentrated in southern and coastal areas, where the climate is more arid and surface water is less available. Additionally, groundwater is being increasingly developed for local systems to augment water supplies in rapidly growing peri-urban areas, particularly Luanda (SADC 2002).

	The centre and north of Angola have many perennial rivers. In the south there are only three perennial rivers: the Cunene, Kuando and Cubango (which flows to the Okavango) rivers.		The centre and north of Angola have many perennial rivers. In the south there are only three perennial rivers: the Cunene, Kuando and Cubango (which flows to the Okavango) rivers.

	The Zambezi River and several tributaries of the Congo River have their sources in Angola. Many rivers originate in the central uplands, but take quite different flow paths. Some flow more or less due westerly to the Atlantic, providing water for irrigation and the potential for hydroelectric power in the dry coastal strip. Two of the largest rivers, the Cuanza and the Cunene, take a more indirect route to the Atlantic, the Cuanza flowing north and the Cunene flowing south before turning west~~. navigable~~. The Kwango and other rivers flow north from the high plateau to join the Kasai River (one of the largest tributaries of the Congo). Some rivers flow south into the Zambezi River system and from there to the Indian Ocean; others to the Okavango River (called the Cubango River in Angola) and thence to the Okavango Swamp in Botswana.
