If you’ve ever wondered why so many South Africans rely on borehole water, the answer is simple: it’s one of the cleanest and most reliable natural water sources we have. But while borehole water can be perfectly safe to drink, it’s not always guaranteed — and knowing the difference is key.
At LiquaFlo Borehole Solutions, we help homes, farms and businesses across Johannesburg’s South region understand their water better so they can enjoy safe, sustainable and cost-effective supply all year round.
So, what exactly is borehole water?
Borehole water comes from groundwater stored beneath the earth’s surface. Over time, rainwater slowly filters through layers of soil, sand, and rock. These natural layers work like a built-in filtration system — removing many impurities long before the water even reaches your borehole.
That’s why groundwater is often cleaner than surface water (like rivers or dams) which is more exposed to contamination.
Why borehole water is naturally clean and safe
Here’s what makes untreated groundwater surprisingly pure:
1. Natural filtration through soil and rock
As water travels underground, sediments trap dirt, debris, and many microorganisms. By the time it reaches the aquifer, it’s been filtered multiple times.
2. Protection from environmental pollution
Unlike surface water, borehole water isn’t exposed to industrial runoff, sewage spills, or surface-level chemicals — making it a safer and more stable supply.
3. Mineral-rich and untreated
Groundwater naturally contains minerals like calcium and magnesium. These minerals not only improve taste but can also offer health benefits.
But here’s the catch — borehole water isn’t always safe to drink
Even though borehole water starts out clean, several factors can affect its quality:
1. Nearby agricultural or industrial activity
Farms, factories, and fuel storage can introduce nitrates, chemicals, or other contaminants into the ground.
2. Old or damaged borehole infrastructure
Cracked casings, faulty seals, or aging pumps can allow contaminants to seep in.
3. Shallow or poorly drilled boreholes
If drilling wasn’t done correctly or didn’t follow standards (such as SABS SANS 10299-1:2003), the water may be at risk.
4. Mineral overload
Some areas have naturally high iron, manganese, or hardness levels — not dangerous, but not ideal for taste, appliances, or plumbing.
How to know if your borehole water is safe
The only way to be completely sure is through a professional water test. LiquaFlo provides comprehensive borehole assessments and tailors purification systems based on your actual results — no guessing, no unnecessary equipment.
Testing typically checks for:
- Bacteria
- pH levels
- Minerals (iron, manganese, hardness)
- Nitrates and chemical contaminants
- Turbidity (cloudiness)
What borehole water can be used for
Depending on its quality and purification setup, borehole water is suitable for:
- Drinking and cooking
- Bathing and household use
- Irrigation and gardening
- Livestock watering
- Commercial and agricultural processes
- Full off-grid water supply systems
With the right filtration and ongoing maintenance, you can safely use borehole water for everything — without relying on municipal supply or rising utility costs.
