Well Field Yield Determination

The correct and scientific yield testing of groundwater resources is often neglected in a South African context. Following the geophysics, drilling and testing of municipal supply boreholes – GEOSS undertook wellfield testing for a wellfield consisting of four production boreholes and several monitoring boreholes. The testing was done according to SANS 10299_4-2003 and the results were analyzed using the FC, Cooper-Jacob and Barker Fracture Flow methods to compare long term sustainable yield predictions of the wellfield. The developed wellfield supplies the town with an estimated volume of over 1.5 Billion Litres per year.
