Planning Your Project
How do I make sure I don't get ripped off?
The first step is education. Request a copy of our “A Layman’s Guide to Borehole Ownership”.
Always deal with a reputable contractor who uses a clear contract detailing deliverables, costs, and delivery times. The Nakiso Borehole Drilling Standard Form of Contract is available on request to ensure both parties are clear on responsibilities.
Where should I drill the borehole?
Start with basic research. Are there producing boreholes nearby? This is a good sign but not a guarantee.
We recommend using a Hydrogeologist to carry out a scientific survey (siting). They use geological maps and geophysical instruments to pinpoint the spot with the best chance of intersecting strong water flows.
Can the drilling rig access my property?
Most residential stands have walls or fences. Getting a 25-tonne rig onto the property can be difficult. You may need to do some deconstruction (e.g., removing a section of a wall) to allow access.
This cost is usually not included in the drilling quote. Discuss access with us beforehand so we can offer a practical solution.
The Drilling Process
What if the driller does not find water?
Your agreement is to drill a hole with the possibility of finding water. If good siting procedures were followed but the hole is dry, you are still required to pay for the drilling.
However, you will not pay for materials like the pump, piping, or electrics, as these are only necessary if water is found.
We hit water! Now what?
After flushing the hole, we perform a Yield Test. This involves pumping water at a measured rate to determine the borehole's sustainable capacity. While this adds a cost, it is crucial for selecting the correct pump size.
Pumps & Installation
What kind of pump do I need?
The pump must match the yield of the borehole. Avoid generic "specials" like a 0.75kW pump unless it matches your specific data.
The electrical installation MUST be done by a qualified electrician familiar with groundwater systems to ensure safety and compliance.
Care & Maintenance
How should I care for my borehole?
- Pollution: Ensure the top of the borehole is sealed to prevent run-off, pesticides, or hydrocarbons from entering the aquifer. Cleaning up a polluted aquifer is expensive and difficult.
- Conservation: Irrigate in the late afternoon to reduce evaporation. Use automatic systems with rain sensors to prevent waste.
What lifespan can I expect?
If installed correctly, you can expect a 20-year lifespan for major components. With proper management, the groundwater resource itself should last for generations.
Is a borehole a good investment?
Absolutely. It adds significant value to your property and provides water security. Over time, the savings on municipal water bills and the benefit of a reliable supply make it a smart financial decision.

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.
