Randfontein sits within the Malmani Dolomite zone, so local geology has a direct effect on drilling method, target depth, expected yield, and installation cost. This page gives you the local picture before you start comparing contractors.
Randfontein has a High (Sinkhole Risk). Use an experienced contractor, insist on a survey before drilling, and review the proposed method carefully.
Local Geology and Water Profile
In Randfontein, contractors usually work through Malmani Dolomite. That determines how quickly the rig progresses, which drilling method is appropriate, and how much uncertainty to expect around yield.
The most common approach here is Odex. Local water quality notes: High yields. Full chemical analysis required due to dissolved minerals.

What to ask local contractors
Ask each contractor to explain the expected depth, how they arrived at the drilling method, what is included in testing, and whether compliance paperwork is covered in the quote.
- Request an itemised quote, not a lump-sum estimate.
- Confirm whether yield testing and water testing are included.
- Check who handles DWS registration and municipality notices.
