How often should a borehole be serviced?
Regular borehole servicing prevents yield loss, pump failure, and costly repairs. Here is how often to service your borehole and what professional maintenance includes.
A borehole that is never serviced will eventually produce less water, consume more power, or fail without warning. Regular professional maintenance is not an optional extra — it is how you protect the investment you made in drilling, equipping, and commissioning.
Many borehole owners in Kenya only call a technician when the pump stops completely. By then, damage may have progressed far beyond what a routine service would have cost.
Recommended servicing frequency
As a general guide for domestic and light commercial boreholes in Kenya:
- Annual inspection — minimum for all active boreholes
- Every 6 months — recommended for high-use systems (irrigation, livestock, multi-unit supply)
- Immediately — if you notice reduced flow, increased power consumption, unusual noise, or discoloured water
Heavy agricultural use, sandy aquifers, or boreholes with history of iron or silt problems may require more frequent attention. Your equipping contractor should recommend a schedule based on test pumping data and local geology at commissioning.
What professional borehole servicing includes
A proper service visit goes beyond switching the pump on and off. Typical scope includes:
- Flow rate and pressure testing against commissioning records
- Pump amp draw and electrical connection checks
- Control panel, starter, and protection device inspection
- Rising main and headworks visual assessment
- Water level measurement and comparison to original static level
- Borehole cap, vent, and sanitary seal inspection
- Advice on sediment buildup, biofouling, or iron bacteria if symptoms present
If yield has dropped significantly, further investigation — such as CCTV downhole inspection or camera survey — may be recommended before attempting rehabilitation.
Signs your borehole needs attention now
Do not wait for annual service if you observe:
- Water output noticeably lower than when commissioned
- Pump running continuously without tank filling
- Higher electricity bills for the same water usage
- Sand or grit in delivered water
- Intermittent tripping of electrical protection
- Visible corrosion or leakage at wellhead
These symptoms often indicate pump wear, partial blockage, falling water level, or rising main damage — all of which worsen with delay.
Servicing vs rehabilitation
Routine servicing maintains a healthy system. Rehabilitation (air lifting, jetting, acid treatment, re-development) restores yield on boreholes that have declined due to encrustation, silting, or biofouling. Rehabilitation is more involved and costly than scheduled maintenance, which is why prevention matters.
Powerwell provides maintenance and after-sales support for boreholes we equip and, where feasible, for existing installations after site assessment.
Protect your water supply long term
The cost of one annual service is a fraction of emergency pump replacement or drilling a secondary borehole because the first was neglected. Build servicing into your property maintenance calendar the same way you would service a vehicle or generator.
