A decision on whether the Otago Regional Council will invest in Tarras Water Ltd's irrigation scheme will be made next week. The Tarras investment - $3.5 million in dry shares and ongoing fixed costs - has been a controversial topic for more than six months.
The council has been putting off a decision until it has all the information it needs.
Council chief executive Peter Bodeker said a staff report pulling together the information provided, the independent advice and the analysis council staff had done would be released with the council agenda on Monday.
The council needed to make a decision so it could set its rates for the coming year.
If it invested, general rates would increase by 5.34%; if not, the rates would go up by 2.97%.
