Why Choose Bonvic Drilling for Your Borehole Project

Drilling a borehole is a decades long water infrastructure investment. The contractor you choose decides whether that investment pays off or fails early. Here is what makes our services different.

✅ Fully Licensed and Compliant

Every borehole we drill is registered with the WRA, environmentally compliant with NEMA, and properly documented. You receive a registration certificate, drilling log, hydrogeological report, water analysis certificate, and operation manual on completion.

✅ Modern Drilling Equipment

Our rigs are equipped to drill from 30 metres in coastal regions to over 300 metres in arid Northern Kenya. We work in every geological condition Kenya has, from weathered rock in Western Kenya to hard volcanic formations in Lower Eastern.

✅ Complete Service Under One Roof

No subcontracting to unknown third parties. From survey to commissioning, every step is delivered by our own engineers, hydrogeologists and technicians. One company. One accountability point. One result.

✅ Lasting Results

A properly drilled borehole should last 30 to 50 years. We achieve that through quality casing, proper grouting, full borehole development and accurate test pumping. Every job is built to last.

1. Borehole Drilling in Kenya

Our core service is professional borehole drilling for residential, agricultural, commercial and industrial clients. Every project begins with a proper hydrogeological survey to confirm where to drill, how deep, and what yield to expect.

We use modern rotary drilling rigs and cased boreholes range from 30 metres in coastal regions to over 300 metres in arid Northern Kenya. The depth and equipment choice depend entirely on your site’s geology, which we map out in our guide to the average water table in Kenya.

What is included:

• Hydrogeological survey by WRA licensed geologists (VES & EM profiling)
• WRA, NEMA and county permit applications on your behalf
• Drilling using modern rotary rigs suited to your site’s geology
• Steel or uPVC casing installation (see our PVC vs steel casing guide)
• Gravel pack and bentonite grout seal
• Full borehole development to maximise yield
• 24 to 72 hour test pumping
• Water quality analysis by certified laboratories
• Drilling log, registration certificate and complete documentation handover

For a complete breakdown of every step involved, read our 2026 guide to drilling a borehole in Kenya.

2. Borehole Equipping & Pump Installation

Once your borehole is drilled and tested, the next step is installing the right pump system. Pump sizing is critical. Install a pump too large and you over draw the aquifer and burn out the pump. Install one too small and your water supply is inadequate.

Our team selects the right pump based on the test pumping data from your borehole. We then size the rising main, electrical supply, control panel and storage tank to match.

What is included:

• Submersible pump selection and supply
• Surface pump options for shallow boreholes
• Pump installation at the correct depth based on test pumping
• Rising main, control panel, dry run protection
• Storage tank supply and installation
• Full system commissioning and handover

3. Solar Borehole Pump Systems

Solar powered borehole systems are one of the fastest growing service categories in Kenya. They eliminate monthly electricity costs entirely, continue working during power outages, and pay back the higher upfront cost within 3 to 5 years for most installations.

Our solar systems are designed for the specific water demand and geographical conditions of your site. We offer pure solar setups for sunny regions and hybrid solar plus grid configurations where dependability matters more than savings.

What is included:

• Solar panel array sized to your pump and daily water needs
• Solar pump controller and inverter
• Submersible solar pump installation
• Battery backup options for evening pumping
• Grid tie capability for hybrid setups
• Lightning protection and proper earthing

4. Borehole Rehabilitation & Maintenance

Older boreholes lose yield. Pumps fail. Water quality deteriorates. We restore these boreholes through professional rehabilitation rather than letting clients waste money drilling a new one.

If your borehole is producing less water than before, has murky output, or makes strange noises, read our piece on signs your borehole needs flushing. For ongoing problems, our complete guide to common borehole problems covers what to look for.

What is included:

• Borehole flushing and cleaning (see our borehole flushing guide)
• Camera inspection of casing and screens
• Pump repairs and replacements
• Yield testing and performance optimisation
• Casing repair or replacement where needed
• Annual and quarterly maintenance contracts

5. Water Tower Fabrication & Installation

Every borehole needs proper water storage to deliver consistent pressure and supply during pump downtime. We fabricate custom elevated water towers from galvanised steel, designed and installed to your site requirements.

Whether you need a 2,000 litre tower for a family home or a 50,000 litre industrial tower for a factory, we build to the specification. All towers are structurally engineered for Kenyan wind loads and local soil conditions.

What is included:

• Custom water tower design and structural engineering
• Galvanised steel fabrication
• Foundation design and concrete works
• Tank supply (plastic or steel, various capacities)
• Installation, plumbing and pressure system setup

6. Water Treatment & Filtration

Finding water is only half the job. Making it safe is the other half. Many Kenyan boreholes have natural fluoride (Nakuru, Naivasha, Baringo), salinity (coastal areas), iron, or bacterial issues that require treatment before the water is safe to drink.

We design and install water treatment systems specific to your borehole’s water analysis results. Read our full guide on borehole water quality testing for the tests every borehole owner should run. We also cover the hidden dangers in borehole water in detail.

What is included:

• Water quality testing at certified laboratories
• Filtration systems for sediment and turbidity
• Reverse osmosis systems for drinking water
• Fluoride removal systems for affected regions
• Iron and manganese removal
• UV sterilisation and chlorination
• Water softening for hard water

You can also use our free water quality test results interpreter if you already have a lab report and want to understand what it means.

7. Irrigation & Water Distribution Systems

For farmers and estate developers, water from the borehole is only useful when it reaches where it is needed. We design and install full irrigation and water distribution systems tailored to your land size, crop type, and water demand.

Our irrigation work spans smallholder farms to commercial agribusinesses. Drip systems for water efficient farming, sprinkler systems for larger fields, and full piping networks for estates and gated communities.

What is included:

• Drip irrigation system design and installation
• Sprinkler irrigation for lawns, farms and pasture
• Pipe reticulation networks
• Pressure boosting pumps and pressure tanks
• Reservoir and water storage solutions
• Crop specific irrigation scheduling guidance

8. Permits & Licensing Assistance

Drilling a borehole without proper permits is illegal under Kenya’s Water Act 2016. The WRA actively decommissions unregistered boreholes, and unregistered boreholes cannot be insured, financed or properly valued.

We handle the entire permit process for our clients as part of our standard drilling service. Most clients never have to visit a single government office. You sign where indicated, we handle the rest.

What is included:

• Water Resources Authority (WRA) authorisation to drill
• National Environment Management Authority (NEMA) EIA licence
• County government no objection letters
• Hydrogeological report compilation
• Final borehole registration with the WRA
• Complete documentation handover
