Why Do Boreholes Collapse - Everything You Need To Know About Water Boreholes

Borehole collapse is a common problem that can be both frustrating and costly for homeowners and businesses in Zimbabwe. 

This article will delve into the primary causes of borehole collapse, providing essential information to help you prevent this issue.

Understanding Borehole Collapse

Borehole collapse refers to the caving in of the borehole walls, often resulting in the complete or partial blockage of the water source. 

Why Do Boreholes Collapse - Everything You Need To Know About Water Boreholes

This can occur due to a variety of factors, including:

Poor Drilling Practices:

1. Inadequate Casing: The most common cause of borehole collapse is the absence or improper installation of casing. Casing is a protective pipe inserted into the borehole to prevent the walls from caving in.
2. Substandard Casing Materials: Using low-quality or recycled materials for casing can compromise the borehole's integrity, leading to collapse.
3. Incorrect Casing Depth: If the casing does not extend deep enough into stable rock formations, the borehole is susceptible to collapse.

Geological Factors:

1. Soil Conditions: Boreholes drilled in unstable soils, such as clay or sand, are more prone to collapse.
2. Groundwater Levels: Fluctuations in groundwater levels can exert pressure on the borehole walls, increasing the risk of collapse.
3. Rock Formations: The type of rock encountered during drilling can affect the borehole's stability. Soft or fractured rocks may require additional support.

Human-Induced Factors:

1. Over-Pumping: Excessive water extraction can lead to borehole instability and collapse.
2. Nearby Construction: Vibrations from construction activities can weaken the borehole walls.
3. Chemical Contamination: The introduction of harmful chemicals into the borehole can erode the surrounding soil and cause collapse.

Preventing Borehole Collapse

To minimize the risk of borehole collapse, it is essential to work with a reputable borehole drilling company that employs experienced professionals and uses high-quality materials.

1. Choose a Reputable Driller: A qualified driller will assess the site conditions and recommend appropriate casing materials and installation methods.
2. Invest in Quality Casing: Opt for virgin casing made from durable materials like PVC or steel. Avoid recycled or substandard options.
3. Regular Maintenance: Monitor your borehole's performance and conduct regular inspections to identify potential issues early on.
4. Avoid Over-Pumping: Excessive water extraction can destabilize the borehole. Implement water-saving measures and consider alternative water sources if necessary.

By understanding the causes of borehole collapse and taking preventive measures, you can protect your investment and ensure a reliable water supply for years to come.

Five Facts About Borehole Drilling That You Need To Take Note Of:
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.

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).

3. The Is No 100% Guarantee On Water: 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.

4. Borehole Siting or Water Surveying 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.

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.
