Understanding Borehole Casing Costs and After-Sales Service: Key Considerations for Your Zimbabwe Project

Planning a borehole for your Zimbabwean property? A reliable water source is essential, and a borehole offers a sustainable solution. But before you embark on this project, it's crucial to understand the costs involved, especially regarding borehole casings, warranties, and after-sales service.

Borehole Casing: The Foundation of Your Water Well

The casing acts as a vital lining for your borehole, protecting it from collapse and ensuring clean water flow. Understanding casing options and their impact on cost is key to making informed decisions.

Casing Class: Strength Matters

The casing class refers to its pressure rating, indicating how much pressure the casing can withstand before collapsing. Here's a breakdown focusing on commonly used classes in Zimbabwe:

  • Class 6 Casing: While available, we generally don't recommend Class 6 casing for most borehole projects in Zimbabwe. It has a lower pressure rating and is suitable for very shallow depths (less than 20 meters) and ideal conditions with minimal stress on the casing. Opting for Class 6 in deeper boreholes or challenging geology can lead to potential well failure in the future.
  • Class 9 Casing: This is a strong and reliable option for moderate depths (around 40 meters) and most ground conditions in Zimbabwe. It offers a good balance between affordability and strength.
  • Class 10 Casing: This is the most robust casing option, designed to handle the highest pressure loads. It's ideal for:
    • Deeper Boreholes: When drilling deeper than 40 meters, the increased pressure on the casing necessitates the extra strength of Class 10.
    • Unstable Geology: If your area has particularly hard rock formations or loose soil, Class 10 casing provides superior protection against collapse.

Casing Diameter: Size Matters for Water Flow

In addition to class, the diameter of your borehole casing is another crucial factor to consider. Here's a general guideline for standard borehole drilling casings in Zimbabwe:

  • 110mm (4.3") Casing: This is a common choice for domestic boreholes with moderate water requirements.
  • 125mm (4.9") Casing: Offers a good balance between water yield and affordability for many household and agricultural applications.
  • 140mm (5.5") Casing: This larger diameter allows for increased water flow, ideal for high-volume water needs like agriculture or commercial applications.

It's important to note that a larger diameter casing generally translates to a higher capacity for water pumping. Nakiso Borehole Drilling can help you determine the optimal casing diameter based on your specific water requirements and project goals.

Warranty Considerations: Peace of Mind with Your Investment

While borehole casing warranties aren't as common in Zimbabwe as in other regions, some manufacturers offer guarantees on specific casing materials and pressure ratings. Here's what to consider:

  • Impact on Cost: Casings with warranties may come at a slightly higher price compared to those without. However, the added peace of mind and potential coverage for material defects can be worthwhile.
  • Warranty Length and Coverage: Carefully review the warranty terms to understand the duration of coverage and what types of issues it addresses. Look for warranties that cover manufacturing defects or material failure within a reasonable timeframe.

After-Sales Service: Your Long-Term Security

Don't just consider the upfront cost – factor in the after-sales service offered by the drilling company. Here's why it matters:

  • Warranty Support: A reputable company will assist you with warranty claims and ensure proper repairs if a casing issue arises due to a covered defect.
  • Technical Expertise: Beyond warranties, reliable after-sales service includes access to qualified technicians for troubleshooting and potential repairs after the initial installation. This ensures long-term well functionality and avoids costly future problems.
  • Preventative Maintenance: Some companies offer maintenance packages to help identify and address minor issues before they escalate. This proactive approach can save you money in the long run.

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.
