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).

A 2014 report stated that 73% of known water systems across Angola use groundwater sources (Cowater 2015). Drilled boreholes equipped with handpumps 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).  
  
 
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 (Groundwater Consultants Bee Pee (Pty) Ltd, SRK Consulting (Pty) Ltd, 2002).
