Borehole collapse is a serious issue that can render a water source unusable and costly to repair. Understanding the common causes and prevention measures can help protect your investment and ensure a reliable water supply.
Common Causes of Borehole Collapse:
- Substandard Construction: Poorly constructed boreholes, using inadequate materials or improper drilling techniques, can be prone to collapse.
- Erosion: Over time, erosion can weaken the borehole walls, leading to instability and potential collapse.
- Groundwater Fluctuations: Changes in groundwater levels can exert pressure on the borehole walls, causing them to shift or collapse.
- Poor Casing: If the casing used to line the borehole is damaged, corroded, or inadequate, it may not provide sufficient support.
- Natural Disasters: Earthquakes, floods, or landslides can cause severe damage to boreholes, leading to collapse.
Prevention Measures:
- Professional Drilling: Engage a reputable drilling company with experienced professionals who use high-quality equipment and adhere to industry standards.
- Proper Casing: Ensure that the borehole is lined with appropriate casing materials that are resistant to corrosion and can withstand the expected water pressure.
- Regular Inspections: Conduct periodic inspections of the borehole to identify any signs of damage or deterioration.
- Protective Measures: Consider installing protective structures or barriers around the borehole to prevent erosion and other external factors from affecting its stability.
- Avoid Over-Extraction: Excessive water extraction can lead to groundwater level fluctuations and increase the risk of borehole collapse.
By understanding the causes of borehole collapse and implementing effective prevention measures, you can significantly reduce the risk of damage and ensure the long-term sustainability of your water source.

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.
