If you’ve been wondering “how much does it cost to drill a borehole?” or “why do prices vary so much?”, you’re not alone. Borehole drilling in South Africa can feel confusing, especially when quotes look completely different from one provider to the next. That’s because the true cost isn’t just about drilling a hole in the ground — it’s a combination of several moving parts.
At LiquaFlo Borehole Solutions, we believe that transparency builds trust. So, let’s break down the hidden (and sometimes overlooked) costs you should include in your borehole budget.
1. Geological Conditions and Site Surveys
Before drilling begins, a geo-survey is often recommended. These surveys help predict water presence, rock layers, and drilling difficulty.
While optional, they can save you money by reducing the risk of drilling in the wrong spot. Hard rock, unexpected clay layers, or deep water tables also impact the final drilling cost.
2. Drilling Depth and Equipment
When people ask “what does a borehole cost?”, depth is usually the biggest factor.
The deeper the borehole, the more time, machinery, and labour involved — which leads to higher costs. South Africa’s geology varies greatly, even within Johannesburg, so depth estimates differ from property to property.
LiquaFlo sub-contracts only SABS-compliant drilling companies (SANS 10299-:2003), ensuring quality, safe drilling that meets industry standards.
3. Casing, Liners & Safety Materials
Many first-time buyers are surprised to learn that casing materials add a sizable chunk to the bill. High-quality SABS-approved casing prevents collapse, protects water quality, and ensures long-term stability. The type and length of casing required depends on soil conditions.
4. Pump Selection and Installation
Once drilling is done, you still need a pump suited to your borehole’s depth and yield. Different pumps come with different price points — from standard submersible pumps to solar-powered options for off-grid independence.
LiquaFlo supplies and installs a wide range of pumps, controllers, pressure regulators, underwater cabling, valves, and fittings — ensuring your system is reliable and tailored to your application.
5. Water Storage, Tanks & Stands
A complete water system often includes storage tanks, stands, and piping. Whether you choose a simple setup or a fully automated pressure-controlled system will influence your overall cost.
6. Purification and Filtration
Not all borehole water is ready to use as-is. Depending on the minerals or impurities found in your water analysis, you may need filtration or purification solutions. LiquaFlo designs custom purification systems based on your water profile — an important cost many buyers don’t anticipate upfront.
7. Electrical Components and Protection
Underwater cabling, control boxes, automatic or manual controllers, and surge protection equipment are essential for safe operation. These items ensure your pump runs efficiently and lasts longer.
8. Maintenance, Repairs & Long-Term Costs
Even the best system needs occasional servicing. Budgeting for annual maintenance, pump checks, and future upgrades will help you avoid expensive last-minute repairs.
LiquaFlo’s maintenance and repair services keep your system running smoothly while extending the lifespan of your equipment.
So, What Should You Realistically Budget For?
While costs vary based on depth, geology, equipment, and water quality, most homeowners and businesses in Gauteng can expect a total project cost that includes:
- Drilling & casing
- Pump & controller
- Tanks & plumbing
- Filtration (if needed)
- Electrical components
- Installation & testing
A transparent, itemised quote from a trusted provider like LiquaFlo makes the process easier and helps you plan for each phase with confidence.
