Borehole Rehabilitation

Bring an existing borehole back to service, often for less than drilling a new one.

About this service

Boreholes lose yield as screens clog and sediment builds up. We assess the well, test what it delivers today, then clean and redevelop it by airlifting, brushing and screen cleaning, and test it again so you can see the result.

Who it is for: Owners of boreholes that underperform, pump sand or have stopped

What you receive

  • Before-and-after test results
  • Works report

Where it fits in the well

Rehabilitation restores the parts a well loses with age: the screen and gravel pack are cleaned and redeveloped until the yield returns.
