Howard Water Allocation Plan

The Howard Groundwater System is a complex groundwater system that underlies a significant proportion of the Darwin Rural Area, including:

  • Humpty Doo
  • Girraween
  • Lambell’s Lagoon and
  • Koolpinyah Station.

Groundwater from the Howard Groundwater System is currently used for:

  • irrigated horticulture (such as mango production and market garden vegetables)
  • industrial purposes
  • rural domestic water supply and
  • to augment the reticulated urban water supply.

Subdivision for rural living and horticultural development has increased demand on groundwater in the rural area.

Since 1980, the number of bores extracting water from the Howard Groundwater System has increased from 200 to approximately 3,000.

A water allocation plan for this groundwater system is currently under development. 

The Howard Water Advisory Committee operated until 30 June 2019.
