Borehole, how much water can I extract
When trying to determine the volume of water one can draw out of a borehole, it is crucial to have an accurate water yield test report. The driller of the hole will conduct a draw down test to determine how much volume the aquiver is providing to the specific well (hole). Should it be producing 100 litre per minute for example, we recommend that the user not install a pump greater than 50% of the yield.
The reason for this is that the actual well will not pull down completely and the level in the hole will remain static with a 50% draw from the yield. Premature borehole collapse is encouraged by rapid adn excess extraction by installing borehole pumps which are capable of removing the full yield volume or even more per minute.
Pedrollo 4 SR submersible deep well pumps provide a quality and efficient solution to both standard and solar power options. In South Africa we do not find any demand at this stage for 6″ pumps.
