Groundwater tools and resources
We've developed several analysis tools to help people assess the effects of groundwater use on the environment.
Well Interference Assessment tool
Our groundwater Well Interference Assessment tool is a web application that allows you to create a PRN file directly from our well and resource consent databases.

Our Excel-based drawdown tool calculates pumping-induced drawdown versus time and drawdown versus distance for radial flow to a well under confined or leaky conditions.
It uses the Theis or Hantush-Jacob functions supplied by Dr Bruce Hunt of the University of Canterbury.
