Water Borehole Drilling in Kenya: Process and Cost

borehole water

In Kenya, boreholes have become a crucial alternative water source, especially in areas lacking a reliable supply of fresh water. While manual digging was once the norm, the advent of drilling machines has revolutionized the Borehole Drilling process. But what is the actual cost of drilling a borehole in Kenya? This article aims to provide a detailed understanding of the process and costs associated with these projects, ensuring informed decisions and effective planning.

Factors Affecting Water Drilling Costs

When it comes to drilling a borehole in Kenya, several factors come into play. These include expenses for environmental impact assessments, NEMA certification, and the actual drilling process. The scale and scope of the borehole project also significantly impact the overall cost.

For real estate developers, landlords, and industrialists, drilling is often the preferred method of ensuring a reliable water supply. This not only addresses issues of water scarcity but also enhances the attractiveness of properties to potential tenants. However, the total cost of drilling hinges on the following factors:

Geographical Location

The geographical location of your drilling site is critical in determining total expenses. Areas with difficult terrain or geological complexity may necessitate specialist equipment and knowledge, thereby increasing costs.

Depth of the Water Table

The depth at which water is found significantly influences drilling costs. Deeper water tables may necessitate more advanced drilling equipment, potentially leading to higher expenses.

Soil Composition

The type of soil at the drilling site is a crucial factor. Soft soils are generally easier to drill through, while rocky or compacted soils may require specialized tools and techniques, thereby increasing costs.

Regulatory Permits and Compliance

Compliance with local regulatory requirements and obtaining necessary permits can add to the overall project expenses. It’s essential to factor in these legal aspects when estimating costs.

How much will it cost to drill a borehole in Kenya?

Despite concerns regarding cost and complexity, the entire borehole drilling operation normally costs between Ksh 1.2 million and Ksh 3 million. A hydro-geological survey is conducted to determine groundwater levels and hydraulic properties. This survey must be carried out by a recognized and qualified geologist.

The Step-by-Step Process of Water Borehole Drilling in Kenya

1. Site Assessment and Survey

The first step involves a thorough site assessment to determine suitability for borehole drilling. This includes geological and hydrogeological surveys to understand the underlying rock formations and water table levels.

2. Obtain Necessary Permits and Licenses

Before drilling can commence, it’s essential to obtain the required permits and licenses from relevant authorities. In Kenya, Once the groundwater potential is confirmed, the drilling company seeks authorization from the Water Resource Management Authority (WRMA) to proceed. This is followed by an Environmental Impact Assessment (EIA) to evaluate the project’s suitability and potential environmental effects. If the National Environmental Management Authority (NEMA) greenlights the EIA findings, licenses are granted for drilling to commence.

3. Mobilization of Equipment and Personnel

Once the necessary permits are obtained, the drilling company will mobilize the required equipment, which typically includes drilling rigs, compressors, pipes, and other specialized tools. Trained personnel, including drillers, geologists, and support staff, will be on-site.

4. Drilling Commencement

The drilling process begins with the setup of the drilling rig at the chosen location. The drilling rig will penetrate the ground to reach the aquifer. The depth of drilling will depend on factors such as the expected water demand and geological conditions.

5. Drilling and Casing Installation

As the drilling progresses, sections of steel casing are lowered into the borehole to prevent the walls from collapsing and to protect the well from contamination. The casing also helps to isolate different aquifers if present.

6. Formation Testing

At certain depths, it’s important to conduct formation tests to assess the permeability and productivity of the aquifer. This involves collecting water samples and measuring flow rates.

7. Installation of Well Screen and Gravel Pack

In some cases, a well screen and gravel pack are installed to filter out fine particles and ensure optimal water flow into the borehole.

8. Development and Well Cleaning

After the drilling is complete, the well needs to be developed to remove any drilling mud, cuttings, and other debris. This is usually done by surging, airlifting, or other methods.

9. Pump Installation

Once the well is cleaned and ready, a submersible pump is installed at an appropriate depth to lift water to the surface.

10. Testing and Water Quality Analysis

The newly drilled borehole is subjected to pump tests to determine its yield and assess its sustainability. Water samples are collected for quality analysis to ensure it meets the required standards for potable water.
