Is your borehole producing less water than it used to?
Is your borehole producing less water than before? Lower yield rarely means the well is dry — sediment, pump wear, and electrical faults are common causes. Here's what to check.
Has your borehole's water output reduced over time? A decline in water production does not always mean the borehole has dried up. In many cases, the problem can be identified and corrected through professional inspection and maintenance — which is why regular professional checks matter before the supply fails.
What causes reduced borehole yield?
Several factors can affect borehole performance. Sediment and mineral deposits may accumulate around the borehole screen, restricting the flow of groundwater. Pumps can also wear out with age, reducing their efficiency — sometimes because the original unit was never matched to the borehole's real yield (see pump selection factors). In some cases, damaged pipes, electrical faults, or changes in groundwater levels may contribute to lower water output.
Ignoring these warning signs can lead to more serious problems, including pump failure, higher energy costs, and interruptions to your water supply. Following a clear servicing schedule helps identify issues early, extending the lifespan of both the borehole and the pumping equipment.
What a professional assessment includes
A professional borehole assessment typically includes inspecting the pump, checking electrical components, evaluating water levels, and conducting performance tests to determine the cause of reduced yield. Once the issue has been identified, appropriate maintenance or rehabilitation can restore the borehole's efficiency — and in some cases test pumping on an existing well clarifies whether the aquifer or the equipment is the constraint.
Powerwell's maintenance and after-sales support covers pump inspection, electrical checks, and yield assessment so you know whether the fix is cleaning, pump repair, or a wider rehabilitation — not guesswork. Where rework or re-equipping is required, we align with the same disciplined approach used across our drilling and equipping projects.
Act early — servicing costs less than failure
Routine servicing is far less expensive than replacing damaged equipment or drilling a new borehole. If you notice a drop in water production, unusual noises from the pump, or increased pumping times, it is advisable to seek professional assistance before the problem worsens — whether you are in Nairobi or elsewhere in our service network.
