CONSENTS granted by the independent commissioners for the wastewater treatment plant and submarine outfall pipe have been welcomed by Mayor Meng Foon.
The conditions for the 35 year consents were common sense, he said.
" I am very happy....This is one of the major decisions which is current council has embarked on, and it is a credit to my team of councillors to support the vision of our community.
"Personallly i have waited 12 years for this consent," Mr Foon said.
The "bug eating bugs" concept of the biological trickling filter (BTF) plant would deliver better cultural acknowledgement, better environmental outcomes and a cheaper running cost of ratepayers.
The project would cost about $5 million less than the previous treatment plant promoted.
It was now estimated to be about $25m opposed to $30m.
"The project is still a big bill and we need to walk cautiously during the implemention stage," said Mr Foon.
"The wastewater committee required by the commissioners will ensure that our community gets the best advice, the best efficiencies and the most effective plant in the world."
