How Borehole Casing Diameter and Quality Can Impact Your Drilling Costs and Long-Term Value

When planning your borehole drilling project, one critical factor that’s often overlooked is the diameter of the casing. Did you know that many service providers in Zimbabwe opt for 110mm casings instead of 140mm to cut costs? While this might seem like a good deal initially, it can lead to long-term problems that undermine the value of your investment.



At Nakiso Borehole Drilling, we prioritize both quality and durability, which is why we always choose 140mm casings paired with high-grade Class 10 PVC. Here’s why our approach stands out.

The Case for 140mm Casings

The diameter of your borehole casing has a direct impact on its longevity, functionality, and future adaptability. Here's why 140mm is a superior choice:

  • Durability: A wider casing provides greater structural integrity, reducing the risk of collapse or damage over time.
  • Enhanced Water Flow: A 140mm casing ensures better water flow rates, optimizing the efficiency of your borehole.
  • Flexibility for Upgrades: With a larger diameter, you can easily upgrade or modify your system to accommodate higher-capacity pumps in the future.

While 110mm casings might save money upfront, they often lead to costly repairs and upgrades, making 140mm a wiser long-term investment.

Why Class 10 PVC Casings Matter

Not all PVC casings are created equal. At Nakiso Borehole Drilling, we exclusively use Class 10 PVC casings because they offer unmatched durability and performance.

  • Strength Under Pressure: Class 10 PVC can withstand high water pressure, ensuring the stability of your borehole in challenging conditions.
  • Resistance to Corrosion: Unlike lower-grade alternatives, these casings resist corrosion, extending the lifespan of your borehole.
  • Low Maintenance Costs: Class 10 PVC is more resilient to environmental factors, minimizing the need for frequent maintenance.

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
Fact 5: Know The Risks
