Wells, bores & groundwater

Stay within the limits if you want to drill a well or bore, and take and use groundwater without needing resource consents.

Wells & bores

You don’t need a resource consent to drill a well (up to 20m deep) or bore (more than 20m deep) as long as you meet the relevant conditions:

Bores

You must:

  • Supply the Council with a copy of the bore log within four weeks of its completion.
  • Ensure the bore is cased and sealed so that there is no leakage from the aquifer.
  • Ensure the bore is more than 50m from any effluent treatment pond, septic tank or silage pit.
  • Ensure the bore is more than 500m from the high-tide mark or any water-supply bore.

Wells

You must:

  • Ensure the well is at least 25m from the sea, adjacent wells and any other water body.
  • Ensure the well is at least 50m from any effluent treatment pond, septic tank or silage pit.

In each case, you will need to apply for a resource consent if you cannot meet these conditions.

Taking and using groundwater

You do not need a resource consent if:

  • You’re taking less than 50 cubic metres a day or 1.5 litres a second.
  • The well or bore is more than 50m from any effluent pond septic tank or silage pit.
  • The well is more than 25m from the sea, any other well or a surface water body.
  • The bore is more than 500m from the sea or other bores.

If you can’t meet these requirements, you’ll need to apply for a resource consent. Your application will be approved if:

  • No saltwater will enter the groundwater as a result of the taking.
  • The water level in any adjacent well will not be lowered significantly as a result of your groundwater draw-off.

If these conditions can’t be met, your application will be assessed and considered by the Council.
