Hydrogeological Survey
Required before you can drill
A geologist maps the aquifer, marks the drilling point and writes the report the Water Resources Authority needs. Skip it and you risk paying for a dry hole.

A borehole that has stopped giving water is usually blocked, not finished.

When a borehole's yield falls, the instinct is to assume the aquifer is finished. It rarely is. Far more often the screen has silted up, the casing has been damaged, or the pump is failing, and all three are fixable for a fraction of the KES 1 million a new borehole costs.
The diagnostic step is a camera inspection, which sends a camera down the hole and shows you exactly what is happening.

100m · air rotary · electric pump
The most common depth in the Nairobi metro. Covers the survey, permits, 100m of air-rotary drilling with casing, test pumping and an electric submersible pump.

150m · air rotary · electric pump
Where the water table sits deeper, as in much of Kajiado, Machakos and the drier counties. Same scope as the 100m package with 50 more metres of drilling and casing.

Per metre · stable rock formation
The standard method where there is solid rock beneath. The per-metre rate already includes mobilisation, casing, graveling, well development and test pumping.

Solar pump, panels and controller
No power bill and no grid dependency, which matters on farms and off-grid plots. It costs more upfront than an electric pump and pays back through saved tokens.

Authorisation to drill
The Water Resources Authority permit and the NEMA environmental licence. Drilling without them is illegal and the borehole can be sealed.
The most common cause is a silted screen: fine sand gradually blocks the slots that let water in, usually because the gravel pack was too thin to begin with. Flushing and redeveloping the borehole clears it.
The next is pump failure, often from a pump sized for more water than the borehole can sustainably give. Then there is casing damage, which lets sand or surface water in and needs a proper repair, not a flush.
A camera run down the hole shows the state of the casing, whether the screen is blocked, the actual water level, and any collapse. It turns a guess into a decision.
Do it before agreeing to any repair. Redrilling a borehole that only needed flushing is one of the more expensive mistakes in this market.

A borehole is five jobs bundled into one: the survey that finds the water, the permits that make it legal, the drilling, the test that proves the yield, and the pump. We run all five for you, with licensed rigs and a quote broken down line by line, so you know exactly what you are paying for before anyone starts.
Tell us where the plot is and what the water is for. We will handle the survey, the permits and the drilling, and come back to you with the likely depth and what it will cost. Countrywide, all 47 counties.

The condition of the casing, whether the screen is blocked, the real water level and any collapse in the hole. It is the step that stops you redrilling a borehole that only needed flushing.
A check every one to two years is sensible, along with keeping the test pumping certificate as a baseline so you can see when yield has genuinely changed.
