Talk to us
Call, WhatsApp or send the form. We ask what the water is for, roughly how much you use each day and where the site is.
Drilling and Investigation
Borehole drilling built to last.
A borehole is a long-term investment, and most of its quality is decided before and during drilling. From our base in Abeokuta, we have drilled more than 1,986 boreholes for homes, farms, institutions and industry, and every one follows the same survey-led process.
What we do
- A site visit and geophysical survey to choose the drilling point
- Drilling to the depth your ground and your water needs require
- Casing and screens chosen for the layers we meet underground
- Gravel packing and development until the water runs clear
- Yield and water-level checks before handover
- Pump, tank and plumbing installation if you want the complete system
When to talk to us
- You are building a home, estate or business and need your own water
- Public supply is unreliable and you are buying water by tanker
- A farm, poultry or livestock operation needs a steady daily supply
- A previous borehole on your land failed, ran dry or gives sandy water
- A school, hotel, hospital or factory needs water it can plan around
How it works
One accountable team from the first call to the day the water flows, and after.
Survey the site
We study the ground before the rig arrives and recommend the drilling point and the depth range to expect.
Drill and case
We drill, install casing and screens, gravel-pack the hole and develop it until the water runs strong and clear.
Test and equip
We check the yield and water level, then install the pump, tank and plumbing if they are part of your project.
Handover and aftercare
We show you how the system works and stay available for servicing and advice.
Why clients choose Onyx
More than 1,986 boreholes (1,579+ residential, 289+ agricultural and 118+ industrial) have taught us how the ground behaves across Ogun State and beyond. You deal with one accountable team from survey to handover, you get a clear explanation of what we are doing and why, and you can still reach us after the rig has left. We are registered with the Corporate Affairs Commission (RC 8215994) and are members of AWDROP, the national association of borehole drilling professionals.

Frequently asked questions
How deep will my borehole be?
Depth is decided by the ground, not a fixed number. The survey shows where water-bearing layers are likely to be, and the final depth is confirmed during drilling.
How much does it cost to drill a borehole?
It depends on depth, ground conditions, casing and screens, and the pump and tank you choose. We give a written quotation after the site visit and survey, so you are pricing your actual site rather than a guess.
Is borehole water safe to drink?
Groundwater quality varies from place to place. We sample and test the water ourselves after drilling and tell you plainly whether it needs treatment before drinking.
Should I do a survey before drilling?
We strongly recommend it. Ground conditions change from plot to plot, and a survey greatly improves the chance of a productive borehole.
What size of borehole do I need?
It depends on what the water is for. A household, a farm and a factory have very different demands, so we design the borehole around your daily water need.
How long does drilling take?
Once the survey is done and the rig can reach the site, we give you a clear schedule for drilling, casing, development and any pump or tank work. Rig access, depth and ground conditions all affect the timing.
Do I need a permit to drill?
It depends on the size and purpose. Large commercial and industrial abstraction can require registration or permits from the relevant water-resources authority, and we will advise on what applies to your project.
Do you drill outside Abeokuta?
Yes. We are based in Abeokuta, Ogun State, and take on projects across Nigeria and the rest of Africa. Tell us the location and we will advise on mobilisation.
