Abstract:
Boreholes are drilled using a variety of techniques including Jetting and Rota-sludge. The video below shows the drilling process from start to finish.
As well as drilling and installing a borehole, it is also important to make a sanitary closure area around it so that animals cannot enter, and the borehole and water remain clean and undamaged.
