Groundwater investigations for Auckland City Council

The 1994 Auckland region drought prompted an investigation into the groundwater resources of the isthmus. Auckland City Council formed a team to identify and develop these resources for both potable and non-potable supplies. Large volumes of groundwater are potentially available from the volcanic formations on the isthmus during a drought. Following the lifting of the drought the schemes were re-examined under normal economic and environmental constraints. Only those potable supplies able to comply with these parameters were selected to continue. Three schemes were chosen to be taken to the Resource Consent application stage. These schemes propose to supply a total of 15000m³/day of potable water to the council’s reticulation network. The applications are currently being reviewed by the Auckland Regional Council.
