He said yesterday he was looking forward to the inquiry getting underway.
"I think it will be an interesting hearing. There are a lot of important issues that the board will have to grapple with. It's similar to a lot of board of inquiry hearings in that regard."
Almost 400 individuals and originations have lodged several thousands of pages of written submissions with the board and dozens of submitters and expert witnesses scheduled to appear before it during the hearing which has been scheduled to run until February.
A range of issues relating to the environmental, social and economic impact of the proposed water scheme will be fiercely debated during the course of the inquiry.
"The reason they [projects such as the Ruataniwha dam] are in front of a board of inquiry is that they're not easy and they're not simple, which is why you have both the process for a board of inquiry and some highly qualified commissioners sitting on it," Mr Robinson said.
Through its investment arm, Hawke's Bay Regional Investment Company, the council is applying for 18 different consents to develop the scheme which, if granted, will operate within the framework of the Tukituki Plan Change, a proposed amendment to the Hawke's Bay Regional Resource Management Plan.
The change, known as Plan Change 6, sets new rules for managing water and land in the catchment and sets limits and targets on nitrogen and phosphorus in the Tukituki River.
