Borehole Rehabilitation restores the performance of a borehole that has lost yield or become blocked by silt, scale, iron bacteria or collapsed sections. It works on the borehole itself. A pump fault is a Borehole Repairs job, and routine checks are Borehole Maintenance.
Describe the drop in yield and the borehole history to get rehabilitation quotes.
Get the Best QuoteWhat Does Borehole Rehabilitation Include?
- Camera inspection. A downhole camera shows casing, fractures, blockages and bacterial growth.
- Airlifting or jetting. Removes silt and debris.
- Brushing. Cleans casing and screens.
- Chemical treatment. Approved products to break down scale and iron bacteria.
- Repairs. Liners or new casing where sections have collapsed.
- Retest. A yield test to measure the improvement.
Who Needs Borehole Rehabilitation?
- Owners whose yield has dropped over time.
- Boreholes producing sand, silt or slimy, discoloured water.
- Old boreholes being brought back into use.
How the Process Works
- Assess. History, yield records and a camera inspection.
- Plan. Cleaning and treatment chosen.
- Treat. Pump removed, borehole cleaned and developed.
- Test. Yield retested.
- Reinstall. Pump refitted at the right depth.
What Affects the Cost?
- Borehole depth and diameter.
- Type and severity of the blockage.
- Methods and chemicals used.
- Casing repairs or liners.
- Retesting.

Limitations
Rehabilitation can only restore what the aquifer can supply. If the water table has dropped, cleaning will not bring back the original yield. Badly collapsed boreholes may be cheaper to redrill.
Frequently Asked Questions
Is it cheaper to rehabilitate or drill a new borehole?
Rehabilitation is often cheaper when the borehole structure is sound. A camera inspection helps decide.
What are iron bacteria?
Bacteria that feed on iron and form slime that blocks fractures and screens, often with orange water and a smell.
Will rehabilitation fix sand in the water?
If the cause is damaged casing or screens, repairs or a liner can help.
