Scientific Borehole Siting: Precision Before Drilling
Nakiso Borehole Drilling is a knowledgeable and experienced borehole siting services company based in Harare but operates across the country. We don't just guess; we analyze the earth.
Borehole siting is the critical first step in establishing a reliable water supply. It involves the scientific assessment of the geological landscape to determine the most promising location and depth for drilling.
At Nakiso, we have specialised and qualified borehole siting personnel and hydro-geologists who undertake comprehensive site visits for assessment purposes. We aim to minimize the risk of dry holes and maximize the yield of your investment.

The Two Approaches to Siting
In Zimbabwe, there are generally two methods used for siting boreholes: the traditional method and the scientific survey method. Understanding the difference is key to your success.
1. The Traditional Method (Dowsing)
Also known as water witching or divining, this practice involves locating underground water using a forked stick, L-shaped rods, or a pendulum. The tool reacts when the individual moves above a potential water source.
Note: Although dowsing can yield results, hydrologists and geologists generally do not endorse the practice as it lacks scientific data verification.
2. The Geological Survey Method
This scientific approach involves the use of electronic resistivity meters and geological maps. These maps show the types of rocks that exist below the ground and the direction of their dip.
By studying the dip of rock units and the topography, our experts can determine the direction of groundwater flow, potential recharge areas, springs, and discharge points.

Deep Dive: How Geologists Find Water
Our process is rigorous. Nakiso geologists analyze data from previous wells drilled in the local area to understand the subterranean environment. We keep a detailed file of rock types penetrated and the quantity of water produced for each well drilled in specific zones.
Advanced Techniques for Difficult Areas:
- Aerial Photography: It is common for hydrologists to examine aerial photos when siting a borehole in a challenging area. These photos often show linear features (lineaments) that may indicate fracture zones beneath the surface where water accumulates.
- Resistivity Sounding: Sending electrical signals into the ground to detect changes in rock resistance, which often indicates the presence of water-bearing fractures.

Fact 1: Know Your Borehole Casings
The Preferred Borehole Casing In Zimbabwe Is Class 9 and 10 (Pressure Classes.)
This is because Class 9 and Class 10 Casings are more collapse resistant. The strength of a Casing is often described as collapse resistance.
Fact 2: Borehole Drilling Depth
The exact depth, of where the water is located, cannot be established by the drilling contractor nor the Water Surveyor (Borehole Siter).
Fact 3: There Is No 100% Guarantee
It is important to note that it is never a 100% guarantee that any hole will yield water, the amount and water quality can also not be guaranteed by the drilling contractor and water surveyor.
Fact 4: Siting Is Important
Making use of a hydrologist or traditional water diviner will increase your chances of having a successful borehole that will yield a sufficient amount of water.
Fact 5: Know The Risks
The risk of the borehole drilling lies with the property owner. The client will still be liable for the drilling costs irrespective of a borehole yielding water or not.
