Key points
- A driller’s quote covers the hole only. Pump, filtration, storage, compliance, and testing routinely add tens of thousands of rands on top of a mid-range drilling invoice.
- Drilling rates range from R310 to R1,500 per metre (Borehole Price Guide 2026), so depth is the single biggest variable in your budget.
- Johannesburg dolomite zones require a hydrogeological study costing R3,000 or more plus written municipal consent 14 days before any drilling (joburg.org.za).
- Filtration is not optional in most South African aquifers, iron, sulphur, and hardness problems are common. Get a SANS 241 water test before buying any equipment.
Why the quote you received is probably incomplete
Ask ten homeowners what their borehole cost and you will get ten different answers, because almost nobody is quoting the same scope. The driller quotes the hole. The pump supplier quotes the pump. The filtration company quotes the filters. The plumber quotes the pipework. Nobody hands you a single invoice that covers all of it, and that is how a R40,000 drilling quote becomes a R120,000 project before the water even reaches your tap.
That gap between the quoted price and the final invoice is exactly what drives people into signing before they understand the total cost. This article breaks every cost layer apart so you can budget for the actual system, not just the hole in the ground.

Layer 1: The hole itself
Before a drill rig arrives, a geo-physical water siting survey costs around R3,000 (LiquaFlo Borehole Price Calculator). This is money well spent. Drilling blind in the wrong spot and hitting nothing useful is a far more expensive mistake.
Drilling rates range from R310 to R1,500 per metre (Borehole Price Guide 2026). The enormous spread reflects geology, casing requirements, and whether you are in a sand aquifer or hard fractured rock. A 60-metre hole at R500 per metre costs R30,000. The same depth in hard rock at R1,200 per metre costs R72,000, and neither figure includes a pump, electrical connection, or a drop of treated water.
One homeowner’s experience on Reddit illustrates the depth gamble perfectly:
