Borehole Drilling Nigeria — Geophysical Siting, Drilling, and Complete Water System Installation
Karoch Engineering provides end-to-end borehole services — from geophysical survey and siting through drilling, casing, pump installation, and water quality testing. We do not drill and leave. We deliver a working water supply.
Borehole Drilling That Delivers Water — Not Just a Hole
The borehole is only one part of the water supply system. The siting survey determines whether there is water to find. The drilling method determines whether the borehole is stable for 20+ years. The pump selection determines whether the flow rate meets demand. The casing protects the aquifer from surface contamination. Karoch Engineering manages the entire chain — from the geophysical survey to the point where treated water flows from the tap.
What We Deliver
▸ Geophysical survey and borehole siting — resistivity and electromagnetic survey to identify the best drilling location
▸ Rotary and percussion borehole drilling — to depths appropriate for Nigerian aquifer conditions
▸ Borehole casing and screen installation — PVC or steel casing and gravel pack for aquifer protection
▸ Pump installation — submersible pump selection, installation, and testing
▸ Borehole yield test — pumping test to confirm sustainable yield and aquifer characteristics
▸ Water quality testing — laboratory analysis of source water quality before treatment design
▸ Rising main and pump controller installation — surface equipment for operational water supply
▸ Integration with water treatment and storage — connecting source to treatment plant and storage tanks
We Drill the Borehole and Supply the Storage Tank — One Contract, One Contractor
Karoch Engineering is one of the few contractors in Nigeria who can drill the borehole, design the treatment system, and supply and install the GRP or Braithwaite storage tank on the same project. For clients who want a complete independent water supply from a single contractor, this is the most efficient route.
FAQ
Common Questions
Q: How deep do boreholes need to be in Lagos?
A: Lagos boreholes typically reach productive aquifers at 50–150 metres, depending on the specific location and the aquifer targeted. Geophysical survey before drilling improves the probability of a successful yield at the optimal depth.
Q: What yield can I expect from a Lagos borehole?
A: Typical Lagos borehole yields range from 2 to 15 cubic metres per hour depending on the aquifer, depth, and borehole diameter. A pumping test after drilling confirms the sustainable yield for system design.
Q: How long does a borehole drilling project take?
A: Geophysical survey: 1–2 days. Drilling: 3–7 days depending on depth and ground conditions. Pump installation and testing: 1–2 days. Full project from survey to operational supply: typically 2–3 weeks
