How big is the property?
Borehole Water Survey South Africa is the work done before the rig books: walking the property with instruments to find the structures that hold water, then marking a target and a likely depth. It costs a few thousand rand against a dry hole that can cost tens of thousands.
- Know what a survey should cost, so you never pay too much.
- Say where the property is and what the water is for, and quotes come back fast.
- From LEADERR APPROVED providers, vetted and backed by many verified 5-star reviews. Peace of mind that the hole is sited by someone with instruments.
Say where the property is and what the water is for, and get survey quotes.

Prices JUST UPDATED. Ballpark figures, rounded, excluding VAT. They reflect typical South African borehole drilling, pump and water treatment rates. They are not our prices or quotations, and no provider is bound by them. Drilling is quoted PER METRE and the depth is not known until the hole is down, so confirm what each quotation includes, such as mobilisation, casing, development and what you pay if no water is found.
What the Instruments Look For
- Magnetics. Finds dykes and intrusions. The contact zones alongside them are where water often sits.
- Electromagnetic traversing. Picks up conductive zones, fractures and weathering across a traverse.
- Resistivity sounding. Gives depth information down a chosen point, so the target has a number on it.
- Geological mapping. The published geology of the area, which sets what is worth looking for at all.
- Existing boreholes nearby. Depths, yields and water levels. The best data there is, and it is free.
- Not dowsing. A survey is an instrument traverse with a plot. Divining is not, and it is not what you are buying.
What a Survey Report Should Contain
- A marked position. Pegged on the ground and given as coordinates, not a vague area.
- A target depth. And the depth range the water is expected in.
- The traverse plots. The data the recommendation was made from.
- A reasoned interpretation. Why this spot and not thirty metres away.
- A second choice. Where to move to if the first hole is dry. This is worth asking for.
- An honest probability. A likelihood, not a guarantee. Nobody can guarantee groundwater.
Where a Survey Pays Most
- Hard rock areas. Where water sits in fractures and a few metres sideways decides everything.
- Large properties. Where there is real choice about where to drill.
- After a dry hole. The expensive way to learn that the first spot was picked by eye.
- High value abstraction. Irrigation and commercial supply, where a weak hole is a failed project.
- Where access is limited. So the target chosen is one a rig can reach.
- Less so in known aquifers. In uniform, well documented ground the local drilling history may be enough.

Get the Best QuoteWhat Affects the Price
- The size of the property. More ground means more traverse lines and more time.
- How many methods. Magnetics alone is cheaper than magnetics plus resistivity.
- The geology. Complex ground needs more lines before a target is defensible.
- Travel. A geohydrologist on site for a day on a remote farm.
- Whether a formal report is needed. A pegged position and a verbal depth is less than a signed report.
- How many targets. A farm wanting three holes is a bigger survey than a stand wanting one.
What to Include in Your Request
- The address and property size. And ideally the erf or farm portion number.
- What the water is for. A garden, a house, livestock or irrigation, and roughly how much.
- Any existing holes. On the property or next door, with depths and yields if you have them.
- Where you cannot drill. Servitudes, buildings, septic tanks, the driveway, planted areas.
- Access. Where a rig can get to, so the target is a usable one.
- Whether you need a report. For a water use application or just to drill from.
Before You Appoint a Surveyor
- Ask what methods they use. And ask for the plots, not just the peg.
- Ask about their success rate locally. And how it is counted. A straight answer here tells you a lot.
- Get a second target. It costs little on the same visit and saves a whole mobilisation later.
- Confirm it is instrument based. If the answer involves rods or a pendulum, that is divining.
- Keep the surveyor separate from the driller. Independent advice on where to drill is worth more.
- Give the report to the driller. Target, depth and the reasoning, so the rig is set up for it.
Borehole Water Survey FAQs
Does a borehole survey guarantee water?
No, and no reputable geohydrologist will say otherwise. A survey finds the structures that are likely to hold water and picks the best available target, which materially improves the odds and gives a sensible target depth. It cannot see water. What it buys you is a better bet and a reason for the position.
How much does a borehole water survey cost?
Around R2,500 to R7,500 on a domestic stand, R4,500 to R12,000 on a smallholding, and R9,500 to R35,000 on a farm with several targets. Against a dry hole at R15,000 to R40,000 and a wet one at R45,000 to R85,000, most people find it is the cheapest decision in the project.
What is the difference between a survey and water divining?
A geophysical survey is an instrument traverse that produces data and a plot, interpreted against the known geology, with a written reason for the chosen position. Divining uses rods or a pendulum and produces neither. Some diviners have a good local record; the distinction matters because only one of the two gives you something a driller or an application can be built on.
How long does a survey take?
A few hours on a domestic stand and most of a day on a smallholding. A farm with several targets can take two days. The report usually follows within a few days, and a target pegged on the ground is normally left before the surveyor leaves.
Should I survey before or after getting drilling quotes?
Survey first if you can. A target depth makes a drilling quote far more useful, because the rate per metre can be put against a likely total, and a driller setting up for a known depth and position prices more sharply than one working blind.
My neighbour has a strong borehole. Do I still need a survey?
It is good evidence and worth telling the surveyor about, but it is not a substitute in fractured hard rock, where a strong hole and a dry one can be thirty metres apart. In uniform, well documented aquifers the local drilling history can be enough, and an honest surveyor will tell you when a desk study is all you need.
Siting is the first service worth booking through Borehole Drillers South Africa and the cheapest way to improve the odds.
