Borehole Rehabilitation in Ghana
A borehole that yields less water, pumps sand or produces poor-quality water is not always finished. Rehabilitation can restore performance in some cases, and the first step is to find out why it declined.
Signs a borehole may need attention
Common warning signs include falling yield, a changed water level, sand or silt in the water, a change in taste or clarity, and a pump that runs but delivers less than before.
- Reduced or inconsistent flow
- Sand or silt in the water
- Noticeable change in water quality
- Pump working harder for less water
How rehabilitation works
The work usually begins with inspection and testing to identify the cause. Depending on the findings, it can include cleaning and redevelopment, repair or replacement of components, and a fresh pumping test to confirm the result.
Frequently asked questions
Is rehabilitation cheaper than drilling a new borehole?
Often it can be, but it depends on the cause of the problem and the borehole's condition. An inspection shows whether rehabilitation is worthwhile.
Will rehabilitation always restore the original yield?
Not always. Some causes can be corrected and others cannot, which is why the borehole is tested before and after the work.
