Borehole drilling is an essential part of Zimbabwe's water infrastructure, providing access to clean and reliable water sources for both rural and urban communities. One critical component of borehole construction is the choice of casing material. Traditionally, metal casing has been the preferred option worldwide. However, in Zimbabwe, there is a growing trend towards using PVC (Polyvinyl Chloride) casing instead. This article explores the reasons behind this shift and why PVC casing is becoming the material of choice for borehole drilling in Zimbabwe.
Cost-Effectiveness
One of the primary reasons for the increasing use of PVC casing in borehole drilling is its cost-effectiveness. PVC is considerably cheaper than metal casing materials such as steel or cast iron. In a country like Zimbabwe, where budget constraints often influence infrastructure development decisions, the affordability of PVC casing makes it an attractive option. It allows more boreholes to be drilled with the available funds, thereby expanding access to clean water sources.
Corrosion Resistance
Zimbabwe's climate, characterized by frequent rainfall and high humidity, can accelerate the corrosion of metal casing materials over time. Corrosion not only weakens the casing but can also contaminate the groundwater, rendering it unfit for consumption. PVC casing is highly resistant to corrosion, making it a durable choice that ensures the longevity and reliability of the borehole. This resistance to rust and decay is particularly advantageous in regions with harsh environmental conditions.
Lightweight and Easy Installation
PVC casing is significantly lighter than metal alternatives, making it easier to transport and handle during borehole construction. This lightweight characteristic simplifies the drilling process and reduces the labor required for installation. In remote or rural areas where access to heavy machinery and skilled labor can be limited, the ease of PVC casing installation is a practical advantage.
Low Maintenance
Once a borehole is drilled and the casing is installed, maintenance becomes a critical consideration. PVC casing requires minimal maintenance compared to metal casing. It does not corrode or rust, eliminating the need for regular repainting or anti-corrosion treatments. This low-maintenance requirement translates to reduced operational costs for borehole owners and ensures that the borehole remains operational for an extended period.
Chemical Resistance
Groundwater composition can vary significantly, with some areas having water that contains high levels of minerals and chemicals. PVC casing is highly resistant to the chemical interactions that may occur between the casing and the groundwater. This resistance prevents the casing from deteriorating or leaching harmful substances into the water supply, thus maintaining water quality.
Versatility and Customization
PVC casing comes in various sizes and can be easily customized to suit the specific needs of a borehole. This versatility allows for flexibility in borehole design and ensures that the casing fits the geological conditions of the drilling site. Whether drilling in rocky terrain or softer soils, PVC casing can be adapted to the situation.
Conclusion
The shift towards using PVC casing instead of metal casing in borehole drilling in Zimbabwe is driven by a combination of cost-effectiveness, corrosion resistance, ease of installation, low maintenance requirements, chemical resistance, and versatility. These advantages make PVC casing an attractive and practical choice for ensuring access to clean and reliable water sources in a country where water scarcity is a significant concern. As borehole construction practices continue to evolve, the adoption of PVC casing is likely to grow, further improving access to clean water for Zimbabwe's communities.

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.
