Nakuru is a rapidly growing city in Kenya, and with increasing population and urbanization, the demand for clean and reliable water sources is higher than ever. Borehole drilling has become a crucial solution for households, businesses, and institutions seeking an independent and sustainable water supply. At Eunidrip Irrigation Systems, we offer professional borehole drilling in Nakuru, ensuring efficiency, cost-effectiveness, and high-water yield.
This article provides in-depth insights into borehole drilling services in Nakuru, covering essential aspects such as the cost of drilling, geological factors affecting the process, and the types of rocks in the region.
Understanding Borehole Drilling in Nakuru
Borehole drilling involves creating a deep hole in the ground to access underground water. The process includes geological surveys, drilling, casing, and installation of pumping systems to ensure a continuous water supply.
Nakuru’s geology plays a crucial role in determining the feasibility of drilling and the costs involved. The city’s underground structure consists of different rock types that impact the ease of drilling and the depth required to reach the water table.
The Water Table in Nakuru
The water table refers to the underground level where water is found in sufficient quantity for extraction. The depth of the water table in Nakuru varies depending on factors such as:
- Location: Some areas have a higher water table, meaning shallow boreholes can provide adequate water, while others require deeper drilling.
- Seasonal Variations: During the rainy season, the water table rises, while it drops in the dry season, affecting borehole productivity.
- Rock Formations: The presence of hard rock layers or porous soil impacts the movement of groundwater and the depth at which water is found.
Types of Rock in Nakuru
Nakuru sits within the Great Rift Valley, which has a complex geological structure consisting of:
- Volcanic Rocks – Predominantly found in Nakuru, including basalt, pumice, and tuff. These rocks influence the drilling method and the type of equipment required.
- Sedimentary Rocks – Some parts of Nakuru contain sedimentary deposits such as limestone and clay. These rocks affect water retention and aquifer formation.
- Alluvial Deposits – Found in low-lying areas, these are loose soil formations composed of sand, silt, and gravel, making drilling relatively easier compared to hard volcanic rocks.
Understanding the rock type in your specific area is crucial in determining the drilling technique and overall cost.
How Much Does It Cost to Drill a Borehole in Nakuru?
The cost of borehole drilling in Nakuru depends on various factors, including depth, rock type, and additional installations such as casing and pumping systems. Here’s a breakdown of the costs:
1. Cost Per Meter
Borehole drilling costs are usually calculated per meter, with rates varying based on the difficulty of drilling through different rock formations.
- Soft soil and alluvial deposits: Ksh 6000 – Ksh 6,800 per meter
- Sedimentary and moderately hard rock: Ksh 6,500 – Ksh 8,000 per meter
- Volcanic and hard rock formations: Ksh 8,500 – Ksh 12,000 per meter
2. Full Borehole Drilling Cost
For a complete borehole project in Nakuru, the cost includes:
- Hydrogeological survey: Ksh 40,000 – Ksh 80,000
- Drilling: Based on depth (average borehole depth ranges from 70m to 250m)
- Casing: PVC or steel casing (Ksh 3,500 – Ksh 6,500 per meter)
- Pumping system installation: Ksh 50,000 – Ksh 200,000 depending on pump type
- Water testing and purification: Ksh 10,000 – Ksh 30,000
Total cost estimates range between Ksh 500,000 and Ksh 3,000,000, depending on site conditions and required depth.

Factors Influencing Borehole Drilling Costs
Several factors impact the cost of borehole drilling services in Nakuru, and understanding these can help you plan accordingly.
1. Geological Conditions
The type of rock formation at the drilling site significantly affects costs. Soft soils and loose sediments are easier to drill, requiring less power and time, thereby reducing costs. However, Nakuru has extensive volcanic rock formations that demand specialized drilling rigs and reinforced drill bits, which increase expenses. The presence of hard rock layers such as basalt may necessitate advanced techniques like air hammer drilling, further elevating the costs.
2. Borehole Depth
The deeper the borehole, the more expensive the project becomes. In areas where the water table is low, more drilling is required, increasing material usage and labor costs. Shallow boreholes (50m – 100m) are cheaper compared to deep boreholes (150m – 250m), which require additional casing and stronger pumping systems to extract water efficiently.
3. Pump Installation
The type of pump selected for the borehole depends on the depth and intended water usage.
- Submersible pumps: These are recommended for deep boreholes and are relatively costly due to their durability and efficiency.
- Hand pumps: Suitable for shallow boreholes and are more affordable.
- Solar-powered pumps: A sustainable but expensive option ideal for agricultural and commercial use.
Choosing the right pump affects the overall cost of borehole drilling services in Nakuru, as installation and maintenance costs vary significantly between models.
4. Casing Material
Casing is crucial for maintaining the structural integrity of the borehole and preventing contamination. Boreholes in Nakuru require durable casing due to the region’s geological conditions.
- PVC casing: A cost-effective option suitable for soft soil formations but may not withstand hard rock pressure.
- Steel casing: More expensive but highly durable, especially for boreholes drilled in volcanic rock regions.
- Stainless steel casing: The most durable but also the most expensive, commonly used for commercial boreholes.
Investing in high-quality casing ensures longevity and reduces the risk of borehole collapse, making it a crucial cost consideration.
5. Water Quality Testing and Treatment
Once drilling is completed, water quality testing is essential to ensure the borehole water is safe for consumption. The cost of testing depends on factors such as:
- Bacteriological and chemical analysis: Testing for contaminants like E. coli, fluoride, and heavy metals.
- Water treatment: If contamination is detected, treatments such as chlorination, reverse osmosis, or UV filtration may be necessary, adding to the total cost.
Ensuring water quality is crucial for both domestic and commercial use, making it an important factor in borehole drilling services in Nakuru.
