The condition of a borehole is paramount to its on-going performance. Checks on newly drilled boreholes ensure that design and specification have been met and allow benchmark readings for monitoring future hydro-geological changes.
Checks to existing boreholes should be made part of an on-going maintenance programme, thus highlighting any potential problems before they develop into major problems or disruptions in supply. Prior to the decision to rehabilitate a borehole, various methods can provide vital information so that the most suitable and economical decisions can be made.
