Database. The data-sets include borehole location (co-ordinates and place name); the
thickness and type of strata intersected; the depth at which water was found; the depth
to which the water rises (water-rest level); yield and the type of pump fitted, if known.
Two consulting engineering firms appointed by the KwaZulu Departmentof Agriculture and
Forestry, namely, Drennan Maud and Partners, P 0 Box 30464, Mayville, 4058, and
Davies Lynn and Partners, P 0 Box 2328, Durban, 4000, have compiled groundwater
resource data-sets for some districts in KwaZulu (see the bibliographic database). The
data concern boreholes and springs, pumps, taps on pipelines, dams and cattle dips. The
data have been plotted on 1 : 10 000 scale orthophoto maps. It should be noted that
1 : 50 000 scale transparent overlay maps shoWing the geographic location of most of the
boreholes drilled in KwaZulu since the mid-1970s, have been compiled by the KwaZulu
Department of Agriculture and Forestry. The data include information supplied by the two
consulting engineering firms.
Chemical and/or bacteriological water quality data (where applicable) for boreholes drilled
inter alia by the KwaZulu Departmentof Agriculture and Forestry, the KwaZulu Department
of Works, and the KwaZulu Water Development Fund are available at the CSIR Division of
Water Technology regional laboratory, PO Box 17001, Congella, 4013, and at the CSIR
Isipingo regional laboratory. (The bulk of the KwaZulu Agriculture and ForestrylWorks data
are available atthe Isipingo laboratory). Groundwater chemical and bacteriological analysis
is also undertaken by Mhlatuze Water, P 0 Box 1264, Richards Bay, 3900, on behalf of
the KwaZulu Departmentof Agriculture and Forestry and the Zululand Joint Services Board
(in the north eastern areas of KwaZulu). The data will be incorporated in the current
NatallKwaZulu groundwater survey (see above). Both yield and water quality data (where
applicable) provided by other organizations such as the Geological Survey of the
Department of Mineral and Energy Affairs; the Natal Parks Board; the Joint Services
Boards; irrigation boards; the (South African) Department of Agriculture, and the (Natal)
Development and Services Board will likewise be included in the groundwater survey of
the province*.
