fREQUENTLY ASKED QUESTIONS

Before any drilling is done, we recommend a hydro geological survey to be carried out. A specialized geologist will walk around the site and pin point different areas where the borehole can be drilled.

Borehole drilling cost varies from depth, and location of the area. Hence we recommend knowing the area to enable us to quote favourably.

The first step in borehole drilling is hydro geological survey which is carried out on the land to check if the land has water aquifers. A report is then done with the findings. This is carried out by a certified geologist.
After this is completed the hydro geological survey report is then taken to the water resource management authority (WRMA) who in turn processes the drilling permit.
An environmental impact assessment report is then done by NEMA to check if the borehole use will affect the environment. This is done by NEMA and a license is given by NEMA.

Once the geologist has surveyed the area, he/she will provide you with a detailed report on the geology of the parcel of land. This report will also indicate the estimated depth of the water and the exact location of the borehole.

A NEMA report consists of an environmental impact assessment report that details the impact of drilling a borehole on the environment. This is a mandatory requirement by law before drilling of the borehole (in Kenya only)

After drilling the borehole and doing test pumping, we will take a water sample to the government laboratory for testing. The test results in a water analysis report that indicates whether or not the water is safe for domestic/industrial consumption.

A good constructed Borehole can last for generations to generations although some boreholes which require rehabilitation after some years to ensure that they are in good working order. In Kenya we have successfully drilled and rehabilitated many Boreholes for commercial and domestic use which are still up and running properly.
Borehole drilling in Kenya will majorly depend on the hydrogeological survey depth estimates for the borehole. Borehole Drilling companies usually dig the borehole according to the recommended depth from the hydro geologists however it can be deeper or shallow as per the conditions found.
We use either Galvanized class B or C pipes or Specialized UPVc pipes. The depth and weight of the pump determines the type of pipes we use.

After drilling and test pumping of the borehole, we take water sample and take it to a government laboratory to be tested. Once the test results are out we offer this to the client with different recommendations.

There are various factors that demonstrate a good drilling company; the experience of the team, the qualifications of key consultants, total understanding of the whole process, type of machinery that is being used; These give an indication of the professionalism and quality of the work that is done.

Borehole drilling is a specialized job as such it requires well-equipped machinery, materials and highly trained personnel to deliver. The cost of inputs such as the fuel used, gravel pack, drilling bits, steel rods, casings and other items that are used in the borehole drilling are costly.

The period depend on many factors; the distance and accessibility to the site, the geology of the landscape and any complications that might arise on the site . Once the rig land the site a borehole of approximately 250M takes 3 to 4 days if no complications.

There are two types of casings available in borehole drilling in Kenya, plastic casing and a steel casing. Plastic casing is cheap and is usually used for depths less than 100 meters because its not strong. On the other hand steel is quite expensive, strong and rigid and can go for large depths however this just like household piping can rust over time.
