Enhancing Borehole Longevity: The Vitality of Double Casing with PVC for Zimbabwean Region

In the heart of Zimbabwe, where water sustains life, the efficacy of borehole drilling cannot be overstated. Yet, the endurance and reliability of these crucial water sources heavily rely on the careful selection of casing materials and techniques. Nakiso Borehole Drilling understands this necessity and advocates for the utilization of double casing, specifically endorsing PVC casings as the ideal choice for optimal functionality.



The Need for Double Casing

Zimbabwe's diverse geological composition demands a robust approach to borehole construction. The prevalent occurrence of fractured rocks and varying aquifer conditions often exposes boreholes to potential contaminants and structural instability. This makes the implementation of a double casing strategy imperative for the protection and preservation of the borehole.

Double casing involves the installation of two layers of protective tubing: an outer and an inner casing. This method serves as a barrier against geological disturbances and ensures the integrity of the water source. The outer casing shields the borehole from external factors like soil infiltration and physical damage, while the inner casing fortifies the well against corrosive elements and maintains water quality.

PVC Casings: Unrivaled Excellence

Among the array of casing materials available, PVC (Polyvinyl Chloride) emerges as a superior choice for multiple reasons:

1. Corrosion Resistance: PVC's innate resistance to chemical reactions ensures longevity and prevents degradation even in aggressive soil conditions prevalent in some regions of Zimbabwe.

2. Smooth Surface and Non-Reactivity: The smooth interior surface of PVC casings minimizes friction during installation and maximizes water flow. Furthermore, it doesn't react with water or soil components, preserving water quality.

3. Strength and Durability: PVC's robustness withstands the rigors of installation and endures the test of time, minimizing the need for frequent maintenance or replacements.

4. Cost-Effectiveness: PVC casings offer a cost-efficient solution without compromising quality, making it an ideal choice for sustainable borehole construction.

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
