Borehole Yield Testing SANS 10299 & BWA Approved

It is of vital importance to apply a yield test before the installation of a pump into a water borehole to determine the water stabilisation level, as well as the exact yield of the borehole. Generally not more than 75% of the yield could be utilised for domestic usage. A borehole yield test need to be conducted to determine with reference to the pump graph which pump is suitable for application.
