Process
How we drill a borehole
Eight steps, about two weeks, and a written record at each one. You always know what is happening on your plot and what comes next.
Step by step
From first visit to first water
Times are typical for a home in Kano metropolis. Larger or remote jobs take longer.
Start with a survey- Day 1
Site visit and survey
An engineer walks the plot with you, checks access and runs a resistivity sounding to pick the drilling point.
- Day 2 to 4
Report and quote
You get the survey graph, the recommended depth and a fixed price quote with stages.
- Day 3 to 7
Permit and booking
We file any drilling notice with the state water authority and book the rig.
- Day 8
Mobilise
Rig, compressor and pipe truck arrive. We protect your compound and set out the mud pit.
- Day 8 to 10
Drill, case and screen
Drilling to depth, logging each layer, then casing, screen and gravel pack.
- Day 10
Develop and test
Airlift development until the water runs clear, then a 6 hour pumping test.
- Day 11 to 14
Pump, tank and treatment
Installation of your chosen pump, tank stand, controls and treatment.
- Handover
Report and guarantee
Drilling log, test results, as built drawing and a 12 month workmanship guarantee.
Before we arrive
What we need from you
A little preparation keeps drilling to the planned days.
Clear access
A gate at least 3.5 m wide and a firm path for a 20 tonne rig.
Water for drilling
About 5,000 litres for mud rotary. We can bring a water tanker at cost.
Someone on site
A person who can open the gate and agree the spot each morning.
Plot documents
Proof of ownership or a letter from the owner for the permit.
Distance from soakaways
At least 30 m from any septic tank or soakaway, we check this at survey.
Daylight hours
We drill from 7am to 6pm and stop for prayer times on request.
Reporting
You get the evidence
Every borehole comes with a drilling log showing each layer, the depth of water strikes, casing and screen positions and the pumping test curve. Keep it, because whoever services the borehole later will need it.

Talk to an engineerYes, though very wet ground can delay rig access. Many clients drill in the dry season when the water table is lowest, which gives a more reliable borehole.
We tell you before you spend on drilling. Sometimes a second point on the plot or a deeper target works.
We lay boards for the rig, contain the mud and leave the site clean. Any damage we cause is repaired.
