Borehole Drilling Price in Kenya and Factors that Influence Borehole Drilling Costs

The cost of drilling a borehole refers to expense or expenditure associated with the process of drilling a borehole in kenya. It includes various factors such as cost of permits, equipment, labor, materials, and other expenses incurred during the drilling operation.

The cost of drilling a borehole in kenya is divided into 3 main components. These compotents are: Cost Hydrogeological survey, Cost of permits, and drilling cost.

The cost of Hydrogeological survey is around 40, 000, The cost of permits is around 50,000. The cost of drilling the actual well is changed per meter; and, it normally comes to Kenya Shillings 5,500 – 6,500 per meter.

The cost of drilling a borehole in Kenya is influenced by factors, including the survey, distance of drilling companies, pricing policies, geological characteristics, depth, pump used, licensing requirements, and the chosen drilling method. Understanding these factors and selecting a reliable drilling company can help individuals, communities, and businesses plan and budget effectively for the installation of a borehole, ensuring a sustainable and accessible water source for the future.

In this article, we will evaluate the 8 Factors that influence the cost drilling a borehole in kenya shown in this diagram.

Factors that Influence Borehole Drilling Costs

8 Factors that Influence the Cost Drilling a Borehole in Kenya

Hydrogeological Survey

A hydrogeological survey is a comprehensive investigation conducted to assess and understand the geological and hydrological characteristics of an area, specifically focusing on the availability, quality, and sustainability of groundwater resources.

A hydrogeological survey is an important part of assessing water resources because it tells us important things about the quantity, quality, and long-term viability of groundwater sources. These studies include thorough investigations to learn about the geological and hydrological features of an area. This helps people make smart decisions about drilling boreholes, planning water supplies, and managing water in a sustainable way. To do a hydrogeological study, we have to use a geologist.

The Physical Distance of Borehole Drilling Companies

The location of the drilling company in relation to the drilling site can affect the cost. If the drilling company needs to travel long distances to reach the site, transportation costs may be higher, therefore increasing the overall cost of the project.

Pricing Policy

The pricing policy of a borehole drilling company refers to the specific approach or strategy adopted by the company to determine the cost of their drilling services. It outlines how the company calculates and presents prices to their clients for drilling a borehole.

Different drilling companies have varying pricing policies. Some may charge a fixed rate for drilling, while others may charge per meter drilled. It is essential to understand the pricing policy of the chosen drilling company to accurately estimate the cost.

Geological Characteristics of the Site

The geological characteristics of a borehole drilling site refer to the specific geological features and conditions present in the area where a borehole is planned to be drilled. These characteristics provide valuable information about the underlying geological formations, which in turn influence the feasibility, cost, and success of the drilling operation, as well as the potential productivity and sustainability of the groundwater source. 

Examples of geological characteristics include: Soil and Sediment Composition, Rock Formations, Aquifer Presence and Characteristics, Faults and Fractures, Groundwater Recharge Potential and Geological Stability.

These characteristics play a crucial role in determining the feasibility, cost, and success of the drilling operation, as well as the potential productivity and sustainability of the groundwater source.

A study conducted by Kuria Zachariah  entitled “”Groundwater distribution and aquifer characteristics in Kenya.” The findings of a study or research project that aimed to assess the groundwater potential of Kenya using the borehole database from the Ministry of Water and Irrigation. The study focused on constructing a transmissivity map to understand groundwater potential and flow patterns across the country.

The geological composition of the site plays a significant role in determining the cost of drilling a borehole. Hard rock formations can require specialized drilling techniques and equipment, which can increase the overall cost compared to drilling in soft soil.

The depth of a borehole refers to the vertical distance from the ground surface to the bottom of the drilled hole. It indicates how deep the borehole has been drilled into the subsurface. The average depth of borehole in Kenya is between a few meters to 300 meters. 

The depth of a borehole is a significant factor that directly impacts the cost of drilling. As the depth increases, the cost of drilling a borehole tends to rise.

Deeper boreholes require more time, resources, and specialized equipment, which can significantly increase the drilling cost. The cost of drilling per meter ranges about 5,500 – 6,500. 

The Pump Used

A borehole pump, also known as a submersible pump or well pump, is a type of pump specifically designed for extracting water from a borehole or well. It is submerged in the water inside the borehole and is responsible for lifting the water to the surface for various purposes, such as domestic water supply, irrigation, or industrial use.

The type and quality of the pump used for extracting water from the borehole can influence the cost. More advanced and efficient pumps may come with a higher price tag but can provide long-term cost savings in terms of maintenance and water extraction efficiency.

Licensing Requirements

To drill a borehole in Kenya, several permits and licenses are required to ensure compliance with regulatory and environmental standards. The specific permits and licenses may vary depending on the location and purpose of the borehole, as well as the local regulations. Here are some common permits required for borehole drilling in Kenya:Water Resource User Permit and Environmental Impact Assessment (EIA). 

Obtaining the necessary permits and licenses for drilling a borehole is a legal requirement in Kenya. The cost of acquiring these licenses should be factored into the overall cost of the project.

Borehole Drilling Method

The borehole drilling method refers to the specific technique or approach used to excavate a hole or well in the ground to access underground water sources. Different drilling methods, such as rotary drilling, percussion drilling, or auger drilling, have varying costs. The choice of drilling method depends on the geological conditions and depth required. Each method has its associated costs, which should be considered when estimating the total cost.

Process of Drilling

The process of drilling a borehole typically involves several steps. After the initial survey, the site is prepared, and the drilling equipment is set up. Drilling begins, and as the borehole deepens, the drilling team may encounter different geological layers. Once the desired depth is reached, the casing is installed to prevent the borehole from collapsing. Finally, the pump and other required equipment are installed to ensure proper water extraction.

Drilling Companies in Kenya

There are several drilling companies in Kenya that specialize in borehole drilling. Some well-known companies include Drilling Technology Kenya Limited. It is important to research and choose a reputable and experienced drilling company that can meet your specific requirements.

Manual Borehole Drilling Cost

The cost of manual borehole drilling can vary depending on several factors, including the location, depth of the borehole, geological conditions, availability of skilled labor, and the type of equipment used. Manual borehole drilling is generally considered to be more affordable than using mechanized drilling rigs, but the expenses can still add up.
