Water Surveys & Siting
Finding the water line before moving rigs.
Find the water before you commit to drilling
Before any rig moves onto your property, our team carries out a geophysical water survey to locate the most promising drilling position. Accurate siting reduces the risk of dry holes and helps you invest with confidence.
This is the stage that happens before any other, and the one that most affects whether the rest of the project goes smoothly. A good survey does not guarantee water, but it meaningfully improves the odds compared to choosing a drilling position without one.

We use ground based instruments to read subsurface conditions across your property, commonly using resistivity and magnetic survey methods. These readings help identify fractured, water bearing rock beneath the surface, rather than relying on guesswork or general assumptions about the area.
Gauteng's geology varies significantly from property to property, including dolomitic ground in some areas and harder quartzite and granite in others. A survey accounts for what is actually beneath your specific site, not just the general area.
Why Siting Matters: Reducing the Risk of a Dry Hole
Drilling without a survey means choosing a position based on convenience or assumption rather than evidence. A survey identifies the strongest water bearing fracture zones on your property first, so the drilling position is chosen because it is genuinely the most promising spot, not simply the easiest place for a rig to reach.
The Survey Process, Step by Step
- 01
Site Walk & Discussion
We walk the property with you, talk through what you need the borehole for, and note any practical constraints on where drilling can realistically take place.
- 02
Geophysical Survey
Ground based instruments are used to read subsurface conditions across the site, looking for the strongest water bearing fracture zones.
- 03
Data Interpretation
Survey readings are interpreted to identify the most promising drilling position and an estimated depth.
- 04
Report & Recommendation
You receive a written report with a recommended drilling position and estimated depth, before any rig moves onto your property.
What's Involved
- On-site geophysical survey and interpretation
- Identification of the strongest water-bearing fracture zones
- Recommended drilling position and estimated depth
- Written survey report for your records
Water Survey Questions Answered
What is a geophysical water survey, exactly?
It is a ground based survey that reads subsurface conditions before any drilling starts, using this information to identify where water bearing fracture zones are most likely to be found on your specific property.
How does a survey reduce the risk of a dry hole?
By identifying the strongest water bearing fracture zones before drilling begins, a survey significantly lowers the chance of drilling in a position with little or no water, rather than choosing a position without this information first.
What geophysical methods do you use to find water?
We use established geophysical siting methods, such as resistivity and magnetic surveys, chosen based on what suits the conditions found at your specific site.
How accurate is the estimated depth from a survey?
The survey gives a realistic estimated depth based on subsurface readings. The confirmed depth is only known once drilling actually reaches water, and ground conditions can still cause some variation from the original estimate.
Do I need a new survey if I already have an old borehole on my property?
It depends on your situation. If you are planning a new borehole nearby, or want to confirm ground conditions have not changed, a fresh survey is worth considering. Ask us and we will advise based on your specific case.
