THE council was not concerned by a recent study's finding the city had "inadequate" water security for the next 20 years.
The Namoi joint organisation of councils has released its water for the future strategy which had 33 recommendations to improve security across the five local government areas.
The report by Rhelm, a specialist environmental and engineering consultancy crew, found Tamworth was "likely to have inadequate water security within the next 20 years, potentially sooner with its forecast residential and industrial growth".
"Water constraints in the medium term will limit the number of water intensive industries able to be sustained," the report said in its recommendations.
However, that finding wasn't a concern for mayor Col Murray.
"Not at all," he said.
"We've known that for a long time."
He said if the city remained at one per cent annual growth it would hit a population of 80,000 by 2041.
Cr Murray said the work was being done now to get funding from the state and federal governments to "ensure that longer term security".
The Namoi Unlimited report found no "immediately viable large scale options" in terms of water infrastructure.
It said potential options included the upgrade of Dungowan Dam with pumped hydro-power and a cross-catchment transfer pipeline from the Apsley-Manning catchments to the Namoi.
"Both of these may involve significant environmental and social impacts which would need to be considered and managed in order for such a project to succeed," the report said.
The research report, which has gone on public exhibition for feedback, found Walcha currently had inadequate security.
Quirindi and some Liverpool Plains' towns had the lowest risk when it came to water security because of the diversity surface and ground supplies it accessed.
