How Deep Should a Borehole Be in Nigeria? (Abeokuta & Ogun State Guide)
One of the most frequently asked questions on Google is: how deep should a borehole be? Discover the factors that determine drilling depth in Nigerian soil.
A question we get almost every day is, 'How deep do you need to drill to get good water?' The truth is, there is no one-size-fits-all answer. The ideal depth of a borehole in Nigeria depends entirely on your local geology and the results of your water survey.
Surface Water vs. Deep Aquifers
In some areas, you might hit water at just 30 meters. However, this is often 'surface water' or a shallow aquifer. Shallow water is highly susceptible to drying up during the dry season (harmattan) and is easily contaminated by nearby soakaways and surface runoff.
To guarantee a pure, uninterrupted water supply year-round, professional drillers aim for deeper, confined aquifers. In places like Abeokuta, this often means drilling between 80 to 150 meters down through solid rock to tap into pristine water veins.
Let the Science Decide
Never let a driller guess the depth. A proper geophysical resistivity survey will tell you exactly how deep the water-bearing rock fractures are located on your specific property before the rig even arrives.
