The Drilling Process

We are a company that has seriously decided to address the challenges of the lack of clean water.

To do this, we have modern water surveying and drilling equipment that meets international standards.

The drilling process starts with a hydro-geological study to locate accurately, where, how deep we have to drill to reach the water which exists underground in the area of study. The reservoirs or underground water springs are known as aquifers.

Once the survey is completed, we then proceed and apply for the required permits and easements as required by the government.

The drilling involves the mobilizing and setting up of the equipment at the site. We erect the mast, and use a spirit level to ensure that the machine is set upright. This guarantees a straight well in to the ground.

Our equipment drills using an air hammer (DTH), which will allow us to penetrate through both dirt/soil and the hard rock underneath, until we reach the determined depth, where there is enough water in the aquifers to feed/charge/recharge the borehole.

Drilling has to be done through a few aquifers, since the yield from the first, second and third aquifers might not be sufficient to sustain the submersible pump that is installed in the borehole. On average, the boreholes in Kenya range in depth from about 150 meters (492Ft) to about 350Meters (1,148Ft) depending on the locality and the geological specifics of the region.

Once water has been struck, we supply and insert the casing/ slotted casing at the well bottom, which basically is a steel or PVC rim that supports the borehole walls to ensure that the walls do not collapse. The option of using PVC versus steel casings is discussed and determined by the customer prior to drilling.

A one meter piece of steel casing is left protruding above the ground level to ensure that run-off rain or other water and silt does not find its way into the borehole.

We then pack the circumference of the well on the exterior of the casing using specially graded sand or gravel that serves as a water filter.

A raised slab is also build around the borehole, which ensures that any sitting water flows away.

The final step is the test pumping of the borehole, a process which allows for measuring how much water the borehole is yielding versus the recharging rate. A portable submersible pump and power generators (if this is no existing power on site) are installed temporarily for testing purposes.

Once installed, water is continuously pumped out of the borehole for a sustained period.

We have high quality of workmanship and skill, which you definitely will experience working with our team.

The actual drilling process, start to finish normally takes 2-4 days depending on depths and eventualities.
