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.
Borehole camera test
Borehole data logger
water quality test
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.
Test Pricing structure
Traveling cost to location, R4.50/km
Before the test can commence the borehole will be handed over to Arena in good order by the drilling company.
If the pump get’s stuck during the lowering procedure the operator will inform the owner.
If requested to continue the lowering process by the client and any damages occur RE: Borehole wall collapses or the pump gets stuck it’s the client will be held liable for the costs of any damages on equipment / Borehole.
Any delay costs caused by the pump getting stuck and/or any scenario not caused by Arena Pumps, the client will be held liable for additional costs.
Delay costs at R350/P-Hour. Not including the test period, applies to faulty boreholes only.
If Arena Pumps suspects any faults, we will recommend a camera inspection to confirm any faults.
Camera inspections costs:
Standard costs R4500.00
Traveling Costs R3.50/Km
Labour Costs R350/P-Hour
