we do for you
We use an underground water detector (up to 150 m) for finding the location of groundwater before borehole drilling.
Our remote sensing technique and technology from Zimgeo uses the natural electric field as electromagnetic field work source, based on the resistivity differences of underground rock, mineral or groundwater, measure the natural electric field in the soil of N different components of electric frequency field .
We provide a report in the form of a curve and profile map showing water depth and location.

We specialise in professional borehole drilling and casing services. Incase loose formation time of drilling,180mm Double casing is recommended.
The Water Borehole Drilling Process In 4 Steps
Step 1 – Hydro-geologists site the borehole
The very first thing that needs to be determined is where the water is, and how we’re going to get to it.
That’s why we employ hydro-geologists who make use of a variety of borehole drilling methods to assess the geophysical properties of the underlying area.
These are the guys that help us ensure we’re not drilling into natural hazards or man-made infrastructure (pipelines, cables, phone lines, etc).
Step 2 – Drilling and Construction
Once the hydro-geologists have helped us prep a path for borehole drilling, we follow through and construct the borehole.
It’s not as easy as Moses and the rock, unfortunately, and, contrary to popular belief, an endless supply of water won’t just surge to the surface following the drilling of the borehole; there are still steps to follow and processes to be completed.
Once the borehole has been drilled the necessary unstable lengths of the borehole are steel cased in an effort to reinforce the ‘tube’.
Step 3 – Determining the yield of the borehole
In order to most accurately gauge the yield of a domestic water borehole an aquifer test is performed.
This involves installing a test pump and pumping borehole water for a fixed set of variables; a given time at a given rate, and then assessing the test’s impact on the water level in the borehole.
Maximum yield is achieved by increasing the abstraction rate, ensuring optimum drawdown of water in the borehole.
Step 4 – Pumping and piping the borehole
The kind of pumping system and piping installed in your new domestic water borehole will largely depend on the intended use of the borehole water.
