Borehole Engineering Services was approached by a global drinks organisation to investigate reduced yield on its wellfield suppyling water to thier production facility in Scotland.
BES were called in by the drinks company along with a consultant to improve the yield on all four boreholes.
The yield on the boreholes had declined over a period of time and were struggling to keep up with production at the factory.
The fisrt part of the project involved removing each pump from its borehole one at a time. This had to coincide with a time that the factory was using the least amount of water to avoid disruption.
The consultant had engauged a Geophysical logging company to log each borehole once the pumps were removed.
During the pump removal of the first borehole, a frog was found attached to the riser section. The riser pipe was a screwed and socketed pipe and in a bad condition so it needed to be cut up, it was also coated in iron residue . Logging was carried out on the borehole, and it was decided not to put this borehole back into production due to the cost spent.
