The court directed the board to rewrite part of the plan change and it is currently working through a process to consider submissions on how it should be reworded.
"The dam has all its consents.
"The dam could start tomorrow but we don't have clarity for the farming community about how they will operate within the plan change," Mr Wilson told yesterday's meeting.
Asked if the council's part-funding of the scheme would push up rates, Mr Wilson said: "The returns projected on that are 6 per cent and it is envisaged that if it gets up and running it will actually help rates."
Grey Power members at the meeting also asked if the regional council was making money by selling aquifer water for bottling. Work is under way at Awatoto on a bottling plant commissioned by a company with consent to take more than 400 million litres of water from a bore on the site.
"I wish we were selling water to China. That would offset the rates even further," Mr Wilson said.
He said water bottlers, like any other extractors such as orchards, had to meet a range of conditions that were agreed with the regional council before consents were granted.
"They've got to have a use very clearly laid out, and volumes very clearly laid out. The impact on the aquifer is paramount to any of these negotiations."
Mr Wilson was also asked if the council was planning to sell its prime asset, Napier Port.
The idea had been "kicked around for years," he said, but "it's not for sale".
