If your borehole has slowed down or stopped producing water, the problem might not require a full redrill. Camera inspection and rehabilitation can restore yield in many cases at a fraction of the cost.
The most common causes of borehole yield decline are biofouling (iron bacteria building up on the screen), silt accumulation in the bottom of the hole, screen corrosion, and pump wear. These problems can often be resolved without drilling a new borehole — but only if caught early enough.
A camera inspection is the first step in any rehabilitation assessment. It costs a fraction of what a new borehole would cost, and it tells you exactly what the problem is before any money is spent on treatment. In our experience, around 70% of boreholes that appear to have failed permanently can be rehabilitated to produce usable yield.
