It is important to select the appropriate class of casing based on the desired pressure capacity to ensure optimal performance.

Distinguishing Class 6, 9, and 10 Casing:

In Zimbabwe, PVC borehole casing materials are classified into Class 6, Class 9, and Class 10, adhering to international standards. These classifications indicate the maximum pressure each class can withstand, providing a standardized measure of casing quality.

Class 6 PVC Borehole Casing:

Class 6 PVC borehole casing is designed to endure a maximum pressure of 6 bars or 600 kPa (kilopascals). It is suitable for applications with low to moderate pressure, such as domestic water supply systems and small-scale agricultural projects. Class 6 casing provides reliable performance in environments where the water pressure remains within the specified limits.

Class 9 PVC Borehole Casing:

Class 9 PVC borehole casing is engineered to withstand a maximum pressure of 9 bars or 900 kPa. It offers greater strength and durability compared to Class 6 casing. Class 9 is recommended for applications involving moderate to high water pressure, including commercial, industrial, and larger-scale agricultural systems. It ensures the borehole's integrity under more demanding conditions.

Class 10 PVC Borehole Casing:

Class 10 PVC borehole casing is the strongest and most robust option, designed to withstand a maximum pressure of 10 bars or 1,000 kPa. It surpasses Class 9 in terms of strength and resilience. Class 10 casing is commonly used in industrial, commercial, and large-scale irrigation systems, providing superior performance in high-pressure environments.

Addressing Misrepresentation Concerns:

Unfortunately, there have been instances outside Zimbabwe where individuals have been misled into believing they are receiving Class 10 PVC borehole casing when they are actually provided with Class 9 casing. This misrepresentation poses risks as the casing may be subjected to pressures beyond its intended capacity, potentially compromising the functionality of the borehole system. At Nakiso Borehole Drilling, we prioritize accuracy and transparency to ensure our clients receive the appropriate casing for their specific requirements.

Advantages of Locally Manufactured Casings:

Nakiso Borehole Drilling sources PVC borehole casings from reputable local manufacturers such as Driptech, Tregers, and Proplastics. Opting for locally manufactured casings offers several advantages over imported alternatives:
  1. Quality Assurance: Local manufacturers adhere to stringent quality control measures, ensuring that their products meet or exceed international standards. By sourcing casings from trusted suppliers, Nakiso Borehole Drilling ensures the delivery of genuine Class 6, 9, or 10 casings, providing clients with peace of mind regarding quality and performance.
  2. Timely Availability: Sourcing casings locally ensures a reliable supply chain and timely delivery. This minimizes project delays and enables efficient borehole installations, allowing clients to access water resources promptly.
  3. Cost-effectiveness: Importing casings can involve additional costs such as shipping, customs duties, and currency fluctuations. Opting for locally manufactured casings eliminates or reduces these expenses, making borehole installations more affordable for clients without compromising quality.
  4. Supporting the Local Economy: Choosing locally manufactured casings contributes to the growth and development of the Zimbabwean economy by supporting local industries and creating employment opportunities.

Nakiso Borehole Drilling is committed to providing accurate information, quality products, and exceptional services. Understanding the distinctions between Class 6, 9, and 10 PVC borehole casing is crucial for making informed decisions regarding borehole installations

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.
