Greater Wellington has used advanced electromagnetic survey technology called SkyTEM to learn more about what's below the Ruamāhanga Valley floor and identify where potential aquifers might be. 

We’ve now made this information available through an online mapping tool. You can use it to explore Ruamāhanga Valley’s potential aquifers. Keep in mind: the tool shows where aquifers may exist, but it doesn’t confirm whether groundwater is actually present.

This guide explains how to use the tools within the interactive map, the information they generate, and the underlying map layers. 

Please see our RuamāhangaSkyTEM project webpage for more information on this project.
