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.

Client Testimonial

I would just like to say thank you to the GEOSS team especially to Corne and Lizanne for their assistance to date. I have learnt a tremendous amount from both of you and enjoyed working with you from day 1. GEOSS has taught me so much about groundwater extraction and the sustainability thereof and you can be sure that I have been referring all companies reps to GEOSS and the amazing services offered. GEOSS has played an extremely critical role at I&J Woodstock and VAP – the value add speaks for itself. I wish the GEOSS team all the best for all future endeavours and sincerely hope you positively impact all other clients the way you have I&J. God bless!
