Geophysical Survey
We find the optimal drilling location before the rig moves in, so you are not left to chance.
DetailsOur Services
Complete groundwater solutions.
From finding the optimal drilling location to installing the pump, Onyx covers every step of your water project with one accountable team.
What We Do
Four services. One dependable water supply.
Choose a single service or let us deliver the complete system. Either way, it starts with understanding your site.
Borehole Drilling
Boreholes for residential, commercial and industrial use, drilled properly the first time.
DetailsStanchion Construction
Strong steel stanchions that safely raise large water tanks for steady pressure.
DetailsPump Installation
The right pump for your borehole, installed by experts, with after-service support.

01
Geophysical Survey
More than 1,986 boreholes have taught us where the water hides. Before any drilling, our team surveys your site to locate water-bearing layers, estimate the depth to drill and pick the best point on your land. It is the step that turns drilling from a gamble into a plan.
- Site visit and geological assessment
- Geophysical (resistivity) survey
- Recommended drilling point and expected depth
- Clear findings explained before you commit
02
Borehole Drilling
A borehole done properly outlasts the hands that drilled it. We drill to the depth the survey calls for, case and screen the hole correctly, then develop and flush it so you get clear water and a long working life — for a family home, a farm, a business or a whole community.
- Residential boreholes
- Commercial and institutional boreholes
- Industrial and agricultural boreholes
- Casing, screening, development and flushing
03
Stanchion Construction
Water needs height to flow well. We fabricate and erect steel stanchions (tank stands) that carry large overhead tanks safely, on proper foundations, so homes, estates, schools and community water points enjoy steady pressure for years.
- Steel tank stands for large tanks
- Proper foundations and bracing
- Tank mounting and plumbing connections
- Community and solar-powered water points
04
Pump Installation
A good borehole deserves the right pump. We size and install pumps — including solar-powered systems — to match your borehole and your daily needs, and we stay available after installation for servicing, repairs and advice. We do right by every client long after the rig has left the compound.
- Submersible and solar pump installation
- Pump sizing for your yield and demand
- Controls, wiring and protection
- Expert after-service support and repairs
How We Work
Four steps to dependable water.
Talk to us
Call, WhatsApp or send the form. We ask about your site, your water needs and your budget.
Survey the site
Our geophysical survey finds the best drilling point and the depth to aim for.
Drill & build
We drill and develop the borehole, then erect the stanchion and install the pump.
Water & aftercare
We hand over a working system and stay on hand for after-service support.
Common Questions
Answers to common questions.
Do I really need a survey before drilling?
Yes. A geophysical survey shows where water-bearing layers are likely to be and how deep to drill. It costs far less than a dry or low-yield borehole, and it lets us give you an honest quote.
How deep will my borehole be?
It depends on the geology under your site. Depths can vary a lot even within one town, which is why we confirm the expected depth from the survey before drilling.
How long does the whole job take?
Once the survey is done and the site is accessible, we give you a clear schedule covering drilling, stanchion construction and pump installation.
Do you build tank stands and install pumps too?
Yes. We can deliver the complete system — survey, borehole, steel stanchion and pump — so you deal with one team from start to finish.
What happens after installation?
We stay available. Our after-service support covers pump servicing, repairs and advice, because we build for the long relationship.
Where do you work?
We are headquartered in Abeokuta, Ogun State, Nigeria, and take on projects across Nigeria and the rest of Africa. Send us your location and we will advise on mobilisation.
