Frequently Asked Questions
There are various factors that demonstrate a good drilling company. These are type of machinery that is being used; the experience of the team and the number of boreholes sank. These give an indication of the professionalism and quality of the work that is done. A Borehole is a lifetime investment it is essential to choose the right company to deliver the standards that you deserve. While drilling 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.
National Water Harvesting and Storage Authority is a very mobile organization in its work and we have dug boreholes in almost every region in Kenya. We have served various communities and done some good work for NGOs in Kenya. In addition to this we have worked with government agencies, county governments and institutions.
As a Water drilling company in Kenya we have not limited ourselves to institutions we have done a lot of boreholes for people who want clean, secure and reliable water regardless of the region.
In some occasions Boreholes can turn out to be dry owing to a variety of reasons such as seasonality changes. The water table is entirely reliant on nature; there is no guarantee that there will be water. In our drilling business we recommend the best hydro-geologists in the market who can give you a better chance of finding water, we have a high success rate and have drilled most boreholes successfully.
A properly constructed borehole can last for an approximate period of 30 years. There are however some boreholes which require rehabilitation to ensure that they are in good working order. In Kenya we have successfully rehabilitated many Boreholes and tested the water content to ensure that the water was clean and safe for use. Many of our boreholes have been used for commercial or domestic use without any problems.
Borehole drilling is a specialized job as such it requires well-equipped machinery, materials and highly trained staff to deliver the right results. The cost of inputs such as the fuel used, steel rods, casings and other items that are used in the borehole are also a bit costly. You can rely on us to give you amongst the most competitive rates in the market.
As a client there are two types of casings available, plastic casing and a steel casing. Water Drilling requires that the borehole uses one material and cannot mix the two materials. Each have their advantages and their drawbacks. Plastic casing while cheaper, lighter and rust proof is also brittle and can break; the casing is usually used for depths less than 100 meters. On the other hand steel is quite strong and rigid and can go for large depths however this just like household piping can rust over time, this should be noted that it takes a while for this to happen, roughly about 75 years.
To help determine the borehole yield and subsequent characteristics. This data is then used in the selection of an adequate sustainable pump for the borehole.
The following factors will either make the cost of a borehole to be high or low:
- Drilling technique determined by the geological formation
- Depth and size of the borehole
- Type of casing
- Borehole Yield/Pump requirements
- Source of power (Electric or Solar)
Boreholes in Kenya are dug according to the hydrogeological survey which estimates the depth of a borehole. Water Drilling companies usually dig the borehole according to the recommended depth from the hydro geologists however can dig further upon a request from the client.
A borehole is dependent 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. Our drilling teams are well versed with many terrains and can deliver in a timely manner. The most typical time for the drilling and equipping of a borehole is a week but can be less or more depending on the above factors.
