Borehole water drilling

What we offer (Our Services)

  1. Underground water Survey

After the agreement has been formalized, our technical team will visit the site along with geologists to identify the best place to carry out the drilling process.

  1. Borehole Drilling

The drilling is carried out the size of the hole can vary depending on the requirement of the client. As the drilling process continuous, geological rock samples are taken at 2 meter intervals. Struck and water rest levels are constantly recorded.

This process enables us to estimate the yield of individual aquifers encountered. Well Casing Once the borehole has been drilled; it must be lined with UPVC casing. The casing process keeps the well open and protects the earth, similar to the efforts to protect groundwater. The hard metal casing shores up the wellbore and extends through both the verticality and the horizontal drilling phases, assuring the long-term integrity of the well from end-to-end. In addition to providing stabilization and keeping the sides of the well from caving in on themselves, casing protects the well stream.


  1. Well Development

 Once the screen, pack, seals and backfill have been installed, the well is developed. This development aims at repairing the damage done to the aquifer during the course of drilling by removing clays and other additives from the borehole. This also alters the physical characteristics of aquifer around the screen and removes fine particles.

We use of pump test as a means of development since it increases permeability in zones. This is an extremely efficient method of developing and cleaning wells.

  1. Well Testing

After development and preliminary tests, a long-duration well test is carried out. Well tests have to be carried out on all newly-completed wells, because not only does this give an indication of the success of the drilling, design and development, but it also yields formation on aquifer parameters which are vital to the hydro geologist.

A well test consists of pumping a well from a measured static water level (SWL) at a known or measured yield, and recording the rate and pattern by which the water level within the well changes. Once a dynamic water level (DWL) is reached, rate of inflow to the well equals the rate of pumping


Today, it is a common practice to carry out a ‘step drawdown test’, in which the yield is increased stepwise. Each step is continued until hydraulic equilibrium is reached after which the yield is increased with 50 to 100%.Towards the end of the test a water sample of 2 liters is collected for chemical analysis

The duration of the test is 24 hours, with a further 8 hours for a recovery test (during which the rate of recovery to SWL I recorded). The results of the test enables the hydro geologist to calculate the best pumping rate, the installation depth, and the drawdown for a given discharge rate


Cost of drilling a borehole

The cost of drilling a borehole depends on the location and depth of the borehole. Kindly get in touch with us for a quotation.
