Pietermaritzburg, 55 p. + app., in an overview analysis <strong>of</strong> certain<br />
borehole records held by the KwaZulu Department <strong>of</strong>Agriculture and<br />
Forestry and the Directorate <strong>of</strong> Geohydrology <strong>of</strong> the Department <strong>of</strong><br />
Water Affairs and Forestry, found that mean borehole yield per<br />
district varied from 1 440·6 120 I h- 1 . Maximum yield per district<br />
varied from 6 120 - 108 000 I h- 1 . Of the 1 211 boreholes<br />
examined in the 19 NatallKwaZulu magisterial districts, 362<br />
boreholes or approximately 30% were regarded as dry (yielding less<br />
than 360 I h- 1 ). The boreholes assessed were those drined since<br />
the early 1970s. Most KwaZulu boreholes are equipped with<br />
handpumps. Better yields are likely in some cases, if engine-driven<br />
pumps were to be fitted. Relatively high yields were noted in the<br />
Ngotshe, Vryheid, Eshowe and Nkandla magisterial districts.<br />

Note: (i) The difference between a well and a borehole was not explained.<br />
(ii) Wells providing usable water were most numerous in the Lower<br />
Tugela, Hlabisa, Port Shepstone and Estcourt magisterial districts.<br />
(iii) Dry wells were a feature <strong>of</strong> the Pinetown and to a lesser extent the<br />
Dundee and Lower Tugela magisterial districts. Water too saline to<br />
drink was found on occasion in the Pinetown and Lower Tugela<br />
magisterial districts.
