Another issue here was the fact that some of the
boreholes had substantial water yields and diverting
the water from the drilling area was challenging.
There was also no Eskom electricity on site but luckily,
this could be overcome with the use of a generator.
“There were no serious challenges, but planning
was important,” explains Holden. “The project was
simplified thanks to a great deal of assistance by the
main construction contractor.” PA
