The Provincial Growth Fund is investing $1.4 million to help Wairarapa gain a clearer picture of the region’s water resources.

The investment will allow the Greater Wellington Regional Council and the three district councils to use SkyTEM, the latest airborne electromagnetic survey technology, to increase their understanding of the region’s water resources.

This in turn will support informed decision-making and better economic and environmental outcomes in Wairarapa.

The new technology finds and maps the geology and hydrology as deep as 300m, giving councils a better understanding of the nature of their aquifers and their characteristics.

Current knowledge and understanding of the area’s groundwater resource has depended on a network of boreholes. However, this information is very site-specific, hugely expensive and spatially limiting compared with the quality and quantity of information SkyTEM can gather.

Co-funding for the $2.5m project is coming from the Greater Wellington District Council, South Wairarapa District Council, Carterton District Council and Masterton District Council.
