The Underground Roadmap: Why Hydrogeological Surveys are Essential for Borehole Drilling in Zimbabwe with Nakiso Borehole Drilling

Drilling a borehole in Zimbabwe, a country with diverse and often complex geology, is a significant investment in water security. However, treating it as a simple "dig and hope" exercise is a recipe for costly disappointment. This is where the Hydrogeological Survey, or Borehole Siting, steps in—it's the critical, scientific roadmap that turns a gamble into a calculated success.


Nakiso Borehole Drilling understands that knowledge is power when unlocking sustainable water. We champion the use of advanced geophysical surveys conducted by qualified hydrogeologists to give you the highest chance of a high-yield, safe, and long-lasting borehole.

💧 What is a Hydrogeological Survey?

Simply put, a hydrogeological survey is a detailed scientific investigation of the subsurface to assess the presence, depth, quality, and sustainability of groundwater. It moves beyond traditional dowsing by using cutting-edge technology like Electrical Resistivity (ER) and Vertical Electrical Sounding (VES) to peer into the earth's structure.

Instead of a vast underground lake, water often flows through aquifers—fractured zones, faults, or porous rock layers beneath the surface. The survey helps pinpoint these specific, water-bearing channels.

💰 Save Money, Increase Success: The Top Reasons to Survey

The cost of a preliminary survey is minimal compared to the loss incurred from drilling a dry hole or one with a low, unsustainable yield. Investing in a survey with Nakiso Borehole Drilling is the ultimate way to safeguard your investment.

1. Confirming Water Presence and Yield

The most crucial function is determining if a viable aquifer exists on your property. The survey identifies the geological structures likely to hold significant water, avoiding the tragic waste of time and money on a dry borehole. It estimates the expected water flow (yield) to ensure it meets your specific domestic, agricultural, or industrial needs.

2. Determining Optimal Depth and Location

Drilling too shallow misses the reliable water source; drilling too deep needlessly increases cost. The geophysical data gives an accurate estimate of the water strike depth, ensuring the drill targets the most productive water-bearing zone directly. Furthermore, it determines the best location on your site for easy access and sustainable extraction.

3. Ensuring Water Quality

Groundwater can sometimes be contaminated with natural minerals like fluoride, high salinity, or bacterial pollutants from nearby septic tanks. A comprehensive survey includes checks and analysis (often by testing nearby boreholes) to identify and mitigate these risks, ensuring your new water source is clean and safe for its intended use.

4. Protecting Your Investment for the Long Term

By understanding the aquifer's characteristics—its size, recharge rate, and the composition of the surrounding rock—Nakiso Borehole Drilling can recommend the correct borehole design and casing class (like the high-strength Class 9 or 10 favoured in Zimbabwe). This prevents premature collapse, reduces siltation, and ensures the sustainability and longevity of your borehole for generations.

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
