How Much Do They Charge for Manual Borehole Drilling on Average?
By Raeli Hydro
If you are looking for a lower-cost way to access groundwater, you may be asking: how much does manual borehole drilling cost on average? Manual drilling can be cheaper than using large mechanized drilling rigs, especially where the groundwater is shallow and the soil is relatively soft.
However, the final price depends on depth, ground conditions, drilling method, casing, location, labour and water requirements. Manual drilling is also not suitable for every site. Hard rock and deep aquifers usually require specialized drilling equipment.
For clients considering a water project, understanding these costs before work starts can help prevent unexpected expenses.
What Is Manual Borehole Drilling?
Manual borehole drilling involves using human-powered or small-scale equipment to create a narrow groundwater well. Depending on the ground conditions, methods may include hand augering, sludging, jetting or bucket augering.
These methods are generally more suitable for shallow groundwater and softer formations.
According to Raeli Hydro, hand-auger drilling can cost approximately KSh 5,000 to KSh 10,000 per metre in suitable conditions, while manual jetting or sludging can make shallow water projects considerably cheaper.
The key point is that manual drilling is not simply a cheaper version of conventional borehole drilling. It has depth and geological limitations.
Average Cost of Manual Borehole Drilling
The average price can vary considerably. A small shallow project may cost much less than a conventional deep borehole.
| Manual Drilling Method | Approximate Cost Per Metre | Suitable Conditions |
|---|---|---|
| Hand auger | KSh 5,000–10,000 | Soft soils and shallow water |
| Manual jetting/sludging | Variable; often below conventional drilling costs | Loose formations and shallow groundwater |
| Bucket auger | KSh 12,000–18,000 | Soft formations, deeper shallow wells |
| Mechanized drilling | About KSh 3,000–10,000+ | Deeper and harder formations |
These figures are indicative rather than fixed quotations. Raeli Hydro reports bucket auger projects of around 50 metres at approximately KSh 800,000–1.2 million, while manual jetting or sludging can cost under KSh 500,000 for shallow projects.
Other 2026 Kenyan market estimates for conventional borehole drilling place drilling rates around KSh 3,000–8,000 or more per metre, depending on the contractor, geology and location.
Why Manual Borehole Drilling Can Be Cheaper
One of the main advantages of manual drilling is the reduced need for large drilling rigs and heavy machinery.
A conventional drilling rig can require trucks, compressors, specialized drill pipes and a larger crew. Transporting this equipment to a remote property can add significantly to the project cost.
Manual drilling equipment is lighter. It can be useful in areas where access roads are narrow or where heavy machinery cannot easily reach the drilling location.
Lower equipment and transport requirements can therefore make a shallow manual borehole more affordable.
However, lower equipment costs do not mean that every manual borehole will be cheap.
Depth Has a Major Effect on Price
Borehole depth is one of the biggest factors affecting the final cost.
A shallow groundwater source may be reached at 10, 20 or 30 metres. Another location may require a much deeper borehole before a suitable aquifer is found.
Hand augering is generally suited to shallow depths. Raeli Hydro lists hand-auger drilling as being suitable for depths of up to approximately 30 metres, depending on the ground conditions.
If the required water source is deeper, a contractor may need to use a more powerful drilling method.
This is why a contractor should not quote a final price based only on the client’s preferred depth. The hydrogeology of the site must be considered first.
Ground Conditions Affect Manual Drilling Costs
The type of material below the ground can make manual drilling easy or extremely difficult.
Soft clay, sand, loose sediments and weathered formations can sometimes be drilled using simple equipment.
Hard rock is a different matter.
If the drilling encounters hard volcanic rock, granite, basalt or other resistant formations, manual equipment may not be practical. Specialized rotary or air-percussion equipment may then be required.
Kenya has very different geological formations across its counties. This is one reason drilling prices vary from one location to another.
Casing Is an Additional Cost
The drilling price is not always the complete borehole cost.
A borehole normally requires casing to help stabilize the drilled hole. Screens may also be installed where necessary to allow groundwater into the borehole while limiting the entry of unwanted sediments.
The type and quantity of casing depend on the depth, diameter, geological formation and borehole design.
A quotation that only gives a drilling price per metre may therefore not represent the complete cost of a usable water source.
Before accepting a quotation, ask whether it includes:
- Drilling
- Casing
- Screen
- Gravel pack
- Borehole development
- Test pumping
- Water-quality testing
- Pump installation
- Transport and mobilisation
Water Testing Is Important
Finding water does not automatically mean that the water is safe for drinking.
Groundwater can contain bacteria, minerals, salts, iron, fluoride and other substances depending on the local geology and surrounding activities.
A water-quality test should therefore be considered after the borehole is developed.
Current Kenyan borehole cost guides place water testing in a broad range depending on the number of parameters tested. Raeli Hydro estimates approximately KSh 8,000–15,000 for water testing in its general cost guide.
For drinking-water projects, testing is particularly important before connecting the source to a household, school, hospital or commercial facility.
Pumping and Storage Add to the Cost
A drilled hole is only the beginning of a water-supply project.
If the groundwater is below ground level, a pump is normally needed to move it to the surface.
The final pump cost depends on factors such as:
- Borehole depth
- Water level
- Required flow rate
- Daily water demand
- Power source
- Pump brand and capacity
You may also need a water storage tank, rising main, electrical system, solar system or distribution pipes.
This means a manual borehole that appears inexpensive at the drilling stage can have a higher final project cost after all the water infrastructure is installed.
Does Manual Drilling Make Sense for Your Property?
Manual drilling can make sense where the groundwater is shallow, the formation is suitable and the required water volume is modest.
It may be suitable for some rural households, small farms, gardens and other projects.
It may not be suitable for large commercial farms, institutions or properties where high water demand requires a deep and high-yield borehole.
A proper hydrogeological survey can help determine whether groundwater is likely to be available and what type of drilling method may be appropriate.
Raeli Hydro’s general borehole cost information places hydrogeological and geophysical survey costs in the tens of thousands of Kenyan shillings, depending on the type of investigation required.
Manual Borehole vs Conventional Drilling
The cheapest option is not always the best option.
| Factor | Manual Drilling | Conventional Drilling |
|---|---|---|
| Initial equipment cost | Lower | Higher |
| Suitable depth | Usually shallow | Shallow to very deep |
| Soft ground | Good | Good |
| Hard rock | Limited | Much better |
| Access requirements | Lower | Higher |
| Large water demand | Limited | Better suited |
| Speed | Generally slower | Generally faster |
| Project flexibility | Limited | High |
The correct choice depends on the water requirement and geology, rather than price alone.
Get a Proper Borehole Cost Estimate
So, how much do they charge for manual borehole drilling on average?
For suitable shallow sites in Kenya, you may encounter manual drilling rates of roughly KSh 5,000–10,000 per metre for hand-auger work, while other manual methods can have different pricing. Bucket auger projects may cost substantially more depending on depth and equipment.
The actual project price can only be estimated properly after considering site conditions, expected depth, drilling method and the required water system.
Raeli Hydro recommends assessing the site before choosing a drilling method. This can help determine whether manual drilling is technically practical or whether a mechanized borehole would provide a more reliable solution.
