"My overall emotion is not one of satisfaction, but sadness that this district has wasted $27 million," he said.
He said the recommendations of such a considered report needed to be implemented and that council always needed to improve its processes and seek best practice.
Jack Bullock said the inquiry achieved what it set out to do "and it came in a lot cheaper than expected so that's a bonus".
"Mr Domm has done an outstanding job over a short period of time on such a complex issue."
He said he "absolutely" supported the recommendations because they highlight potential issues and risks.
Ray Stevens he was satisfied with the Domm report and he supported the recommendations "that clearly lay a path for transparent processes heading into the future".
Philippa Baker-Hogan said she wasn't happy with the review because it failed to address the question if the original plant was salvageable.
"It's telling us what we already know - the old plant failed."
And she claims the report has been truncated three and-a-half weeks early in an attempt to influence the coming election but didn't explain how.
However, she did support the recommendations Mr Domm has made.
Sue Westwood she supported the Domm report and especially its recommendation of a more rigorous reporting regime to Horizons Regional Council.
Rob Vinsen said he supported the need for this inquiry "in the misguided belief that the question 'Is the current plant salvageable' would be independently addressed.
"That Mr Domm did not address this question - the only question that really matters now - is not his fault. The terms of reference ruled out seeking technical advice," he said.
"It's tragic, for ratepayers especially, that no resolution of the key questions is offered by the inquiry."
Former Whanganui mayor Michael Laws welcomed the findings of the report.
"I feel very sorry for the governance team that is elected next month, and the good folk of Whanganui, that they will inherit the consequences of such management...of 12 years ago," he said.
Mr Laws said the findings in the report that senior managers misled the mayor and councillors of the time, "still has the capacity to shorten one's breath. You do wonder if [charges] should not be considered."
THE RECOMMENDATIONS
Among the recommendations Robert Domm has flagged are:
* amend council's procurement policy to cover provisions for major procurements over $1 million (current policy threshold is $200,000)
* review council's tenders board processes to ensure value for money, quality and fairness
* independent peer reviews and risk assessments for major projects must be considered and approved by full council
* strenghten council's internal procedures covering annual consents reports and notices of non-compliance to Horisons Regional Council
* Local Government NZ and central government consider creating guidelines for water and wastewater treatment infrastructure to assist smaller councils
* revise and strengthen council's trade waste by-law
