Arena Group has Satellite Units placed over the Eastern and Western Cape.
With a Core Unit in both Clanwilliam and George.
We’ve got a fleet over 18 vehicles servicing a broad spectrum of clients.
Equipped with 7 Borehole testing units in the area & qualified technicians.
We also offer Borehole Camera inspections and Data Logging.
This allows us to examine walls, casings, screen, gravel, deteriotation and perforation blockage and/or other physical problems.
The inspection is visible on a live inspection and recorded on a storage device to be analysed after inspection.
Such measurements can include: air temperature, relative humidity, barometric pressure , temperature, water level, dissolved oxygen, rainfall.
We offer testing services ranging from:
The Yield test calculates the maximum water that can be pumped out of the borehole and the time it takes to recover the recharge of water from the water source/vain.
The Flow is calculated to never drop lower than the strike/Water source.
Step Test :
During this test the pump rate is increased in steps at regular intervals. These intervals will be calculated after assessing the borehole.
Constant rate test duration ranges from 8-48 Hours (not exceeding 48 Hours), the time is usually calculated proportional to the yield test.
During the recovery, the draw down is calculated measuring the level directly after the constant rate test.
The quality of the water is very important, especially for domestic purposes.
The Samples are send to Test Lab for a detailed analysis report.
