A total of 81 non-binding agreements have been signed from people interested in buying water from the proposed Ruataniwha dam in Central Hawke's Bay.
The "expressions of interests" signed and recorded by the water storage scheme's commercial manager, Duncan McLeod, represent a total of 30 million cubic metres of water covering 9400ha.
Mr McLeod presented an update on buyer interest to the Hawke's Bay Regional Council on Wednesday. It was part of the council's investment company's report on progress on the Tukituki Catchment Proposal which included the Ruataniwha dam and Plan Change 6, measures to improve management of the catchment environment. He said a prospectus was expected to be released towards the end of the year.
Nailing down an accurate price to buy the dam's water would evolve once a builder to construct the dam was selected, and the construction costs defined. Bids from international companies Obrascon Huarte Lain and Bouygues Construction were being evaluated by a panel of 34 people, including seven selection members, involved in covering commercial, technical, economic and environmental compliance aspects of the scheme.
Representatives of each bidder were also being put through a question and answer process over a few weeks. A final decision on the winning bid was expected next month.
