Figure 3:<strong>Swaziland</strong> river networkGroundwater resources have been poorly studied and exploited in <strong>Swaziland</strong>. A surveycarried out between 1986 and 1991 by the Department of Geological Surveys and Minesconcluded that the groundwater potential was equivalent to a sustained flow of 21 m 3 /s, ofwhich 1,400 boreholes had tapped only 6% by 1992. To date there are over 2,000 boreholesin <strong>Swaziland</strong>, most of them (over 1,340) in the <strong>Swaziland</strong> portion of the Maputo River basin.It is estimated that the groundwater recharge rates range between 2 and 10% of averageannual rainfall.RDMU (<strong>Strategic</strong> Environmental Assessment of the National Adaptation Strategy) - Page 24
