A major step to stop treated waste water going into rivers has been taken by South Wairarapa District Council.
The council has bought 118 hectares alongside the town's waste water treatment plant for $2.8 million.
Mayor Adrienne Staples said the unexpected chance to buy the land, bounded by the Waiohine and Ruamahanga Rivers, was "too good to miss".
"This land will eventually take most of Greytown's treated waste water, instead of it being discharged into the rivers," Mrs Staples said.
An irrigation system would be installed on the land when funding permitted, but in the meantime the land would be let for grazing to offset the price. The purchase would be funded by borrowing and rates will be in line with those forecast in council's 2012/22 Long Term Plan.
