YIELD TESTING

The yield test is completed in order to establish the sustainable yield of the borehole in litres per hour.  This allows for us to correctly size the pumping equipment required.

How is this done? – We record the Static Water Level – that is the natural groundwater level in the borehole.  We then install a test pump to allow for controlled pumping of the borehole.  During pumping, two items are monitored and recorded – the drawdown (lowering of water table in the borehole) and the discharge (or pump yield).  This information allows us to quantify how much water can be extracted L/hr from this borehole. On completion of the test (which can range from 3 hours to 72 hours) the pump is shut off and the water level in the borehole is recorded as it recovers (called the “recovery”).  This recovery information and other data is used to make predictions on the sustainability of the aquifer from which the borehole is drawing the water.

With the yield test results we will be able to assist you with planning the pumping system for your borehole.

WATER QUALITY TESTING

During the yield testing two samples are collected for chemical analyses.  One sample is for microbiological analyses (Sterile bottle) and the other for macro elements (anions & cations).  The typical test undertaken is known as the SANS-241 drinking water test.  The results of these tests will allow for the appropriate treatment / filtration options to be recommended to make your water safe to drink and safe for your pipes.

Domestic Boreholes uses accredited laboratories and will provide you with a report explaining the results of the chemical analysis including suggestions on how to filter your water to resolve any problems with the quality.
