Water drilling licences

Before drilling a bore

Drillers need to follow these steps before drilling a water bore:

Step 1. Get a Registered Number (RN) from your regional Water Resources office. Your RN is unique. It must be displayed on the bore and included on the statement of bore form.

Step 2. If you are drilling in a water control district, you must read, understand and follow the conditions on the valid bore work permit.

Step 3. Fill in and submit a statement of bore to Water Resources for each bore within 28 days of completion.

Step 4. Submit strata and water samples to Water Resources for each bore within 28 days of completion.

Strata samples need to be 250g secured in sealed bags of each change in strata observed in the bore, while water samples of one litre need to be taken from each water-bearing bed found in the bore unless you have an exemption on the bore construction permit.

Responsibilities before bore construction

As a bore driller you have all of the following responsibilities before you begin drilling:

  • make sure the drilling is legal
  • bore design needs to suit the hydrogeological conditions, protect the aquifer, suit the purpose of the bore and meet the client's needs
  • the bore needs to be constructed by a qualified driller that has experience and the relevant class of licence and endorsement
  • a bore needs to be located to meet separation needs and provide a reliable and useful water supply
  • get all information on the hydrogeological conditions in the area
  • water bores should be a safe distance from possible sources of contamination, or designed and built to stop contamination
  • make sure the location meets any conditions in the bore permit
  • collect formation samples to work out the nature and type of strata and to confirm any changes in the formation
  • choose drilling fluids that help the drilling process, remove cuttings from the borehole and limit damage to formations
  • do not add chemicals and other drilling fluid that can leave a residual toxicity to any drilling fluids or cement slurries such as grout.
