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.
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. At Apexx Boreholes & Engineering Co. we treat each borehole like our first with a lot of care and attention; this ensures that you have a quality product for generations to come at pocket friendly prices. We are a listening partner in the field of borehole drilling in Kenya.
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. At Apexx Boreholes & Engineering Co. we try our level best to ensure the price given to our clients is still reasonable compared to other service providers?
The period depend on many factors; the distance and accessibility to the site, the geology of the land scape 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.
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.
After drilling the borehole and doing test pumping, ABEco 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.
Borehole Drilling cost in Kenya varies due to many aspects. The main cost of drilling borehole is largely dependent upon the depth and amount of casing that the borehole will require. Drilling cost is per depth (metres). The type of Geology that we have to drill through does have some influence as well as the actual ground conditions. Although many people think that the easiest way to drill a borehole in kenya is through the soft and loose geologies. However, this is not the case, in fact, the opposite is true. This is made more difficult if the hole is collapsing due to the ground being loose. Clients distance from our head quarters in Nairobi will also affect slightly the costing of drilling. The drilling diameter also is considered during costing. We usually start our borehole drilling at a larger diameter of about 20.3 cm (8 inch) to allow the casing be installed thro the soft upper regions thereby prevent collapse. The borehole drilling is then continued at 16.5cm through the solid rock to the target depth or water strike. After drilling the following activities follow;
