Where to Drill a Borehole: How Professionals Choose the Best Spot

If you’ve ever wondered “Where do I drill a borehole on my property?” or even “Where does borehole water actually come from?”—you’re not alone. Borehole drilling is an investment, and choosing the right location is one of the most important steps to ensure a reliable, long-lasting water supply. This is where specialised geo-surveying and expert assessments come into play.

At LiquaFlo Borehole Solutions, selecting the perfect borehole site isn’t guesswork—it’s a science backed by experience, technology, and professional geohydrological insight.


Where Do Boreholes Get Water From?

Before choosing a spot, it helps to understand where the water actually comes from. Boreholes tap into underground water-bearing layers called aquifers. These aquifers store water between rocks, gravel, sand, and fractures deep underground. The goal is to identify these water-rich zones and drill exactly where they’re most productive.

But because aquifers vary across Gauteng—sometimes even from one property to the next—professionals rely on structured assessments to pinpoint the best drilling spot.


How Professionals Choose the Best Drilling Location

1. Geophysical (Geo) Surveying

This is one of the most important steps in modern borehole drilling. Using specialised instruments, technicians scan the subsurface to detect fractures, faults, and underground water pathways.
A geo-survey helps determine:

  • Depth of water-bearing formations
  • Best drilling direction
  • Areas with the highest likelihood of strong water yield

LiquaFlo uses trusted geophysical partners to ensure all surveys comply with SABS standards and are performed with precision.

2. Geohydrological Assessments

Once the survey is complete, the data is interpreted by trained professionals who understand Gauteng’s geological conditions. They analyse:

  • Soil and rock composition
  • Aquifer structure
  • Water movement patterns
  • Potential risks like contamination or collapse

This assessment guides the exact drilling point and expected depth.

3. Avoiding High-Risk Areas

Professionals also look at risks that may affect borehole performance, including:

  • Foundations or building structures
  • Septic tanks or sewage lines
  • Underground utilities
  • Flood zones
  • Low-yield areas identified in surveys

This ensures the borehole stays safe, efficient, and compliant with regulations.

4. Local Expertise Matters

LiquaFlo’s team has years of experience working across Johannesburg and surrounding areas. Because groundwater conditions can vary dramatically from street to street, local knowledge becomes a huge advantage when predicting the most reliable drilling point.


Why the Right Location Matters

Choosing the right borehole location affects everything—from the strength of your water flow to the longevity of your pump. A properly positioned borehole ensures:

  • Better water yield
  • Lower risk of contamination
  • Longer pump lifespan
  • Fewer repairs and maintenance issues

In short, a well-chosen drilling site saves you money and stress over the long term.

Frequently Asked Questions

Where do boreholes get water from?
Boreholes draw water from underground aquifers—natural layers of rock, sand, and gravel that store groundwater.
How do professionals find the best spot to drill?
They use geo-surveys, geohydrological assessments, and local geological expertise to identify the most productive and safest drilling point.
Can I choose the drilling spot myself?
You can give input, but a professional assessment ensures accuracy, better water yield, and long-term reliability.
Is a geo-survey necessary?
While not legally required, it significantly reduces drilling risks and increases the chances of finding a strong, reliable aquifer.
How close can a borehole be to buildings?
Professionals typically avoid drilling near foundations, septic tanks, and utilities to ensure safety and prevent water contamination.
