You will need this licence to undertake water bore activities, such as carry out drilling operations in artesian and sub artesian aquifer systems.
Driller's licences are classified according to aquifer type and are endorsed with the drilling methods that may be used. This ensures the skills, knowledge and experience of a driller match the groundwater protection requirements. The classifications are:
- Class 1: permits work in non-flowing (subartesian) single aquifer systems.
- Class 2: in addition to operating in Class 1 conditions, permits work in non-flowing (subartesian) multiple aquifer systems.
- Class 3: in addition to operating in Class 1 and 2 conditions, permits bore drilling in flowing aquifer systems.
The drilling method endorsements are for cable tool, auger, rotary air, rotary mud, non-drilling rig and sonic drilling. Water bore drillers must have the correct licence endorsements for the construction of new bores or any other work on an existing bore.
