Borehole Drilling is an essential aspect of water resource management in Zimbabwe, where access to clean water is critical for domestic, agricultural, and industrial purposes.
What is Borehole Casing?
A borehole casing is a pipe that lines the drilled borehole to prevent it from collapsing and to keep out contaminants.Borehole Casing: Understanding the Difference Between Class 6 and Class 10 in Zimbabwe |
What is Class 6 Borehole Casing?
Class 6 borehole casing is a PVC casing with a wall thickness of 1.5mm. It is the most common borehole casing used in Zimbabwe, and it is suitable for shallow wells with a depth of up to 100 meters. Class 6 casing is cost-effective, lightweight, and easy to install, making it a popular choice for small-scale borehole projects.What is Class 10 Borehole Casing?
Class 10 borehole casing is a PVC casing with a wall thickness of 2.0mm. It is a more robust casing option than Class 6 and is suitable for deeper wells with a depth of up to 250 meters. Class 10 casing is more expensive than Class 6, but it is more durable, providing better resistance to pressure and bending forces.Key differences between Class 6 and Class 10 borehole casing
- Wall thickness: The main difference between Class 6 and Class 10 borehole casing is their wall thickness. Class 10 casing has a thicker wall, providing greater strength and durability than Class 6 casing.
- Depth of well: Class 6 casing is suitable for shallow wells with a depth of up to 100 meters, while Class 10 casing can be used for deeper wells with a depth of up to 250 meters.
- Price: Class 10 casing is more expensive than Class 6 casing due to its increased strength and durability.
Which casing is best for your borehole project in Zimbabwe?
The choice of casing depends on several factors, such as the depth of the well, the geology of the area, and the budget available for the project. If you are drilling a shallow well with a depth of up to 100 meters, Class 6 casing may be suitable. It is cost-effective and easy to install, making it a good choice for small-scale borehole projects.borehole casing is an essential component of any borehole drilling project in Zimbabwe. Choosing the right casing type, whether it be Class 6 or Class 10, will ensure that the well is efficient, safe, and long-lasting.

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.
