Here’s a few answers to our most common questions.
The cost of drilling a borehole depends on the location and depth of the borehole. Kindly get in touch with us for a quotation
Being a long-term investment, how long a well will last can depend on many factors. If taken good care of, a good borehole dug by Tiwi Drilling Limited in Kenya can last through generations. Additionally, the duration before the borehole runs dry may depend on the availability and sustainability of the underground water levels and amounts.
The good thing is that the best service providers will always have a hydro-geologist, who is an expert that determines the water table levels in an area long before a borehole drilling project begins. Most of these specialists are so good at their job that rarely does a borehole drilling project fail to produce water. However, it is important to be advised that some wells may require renovation for them to last long.
- Geological/Hydrological Survey carried out by a registered geologist in the designated country.
- Water Resource Management Authority (WRMA) Authorization.
- Conducting Environment Impact Assessment (EIA) & getting License from NEMA
- No Objection Letter from Water Service Provider like Nairobi Water Company
If required, we can assist in acquiring the above permits and licenses.
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.
Borehole drilling services in Kenya may vary among service providers. However, there are those common tasks that Tiwi Drilling will handle. These are:
- Borehole equipping.
- Plumbing and piping.
- Borehole cleaning.
- Underground water surveys.
- Test pumping.
- Borehole renovations and servicing.
- Water level assessment.
