After the review of the plan which predates the amalgamation of Dubbo City Council and Wellington Council, it will be placed on public exhibition.

The council's new director of Infrastructure Julian Geddes announced the review of the plan at its public information session about water on Tuesday.

He later acknowledged the water restriction triggers in the document "won't line up with where our level of restrictions are now".

Rather than solely relying on a table of triggers in the plan, Mr Geddes said the council had taken into account "new circumstances" including zero inflows into Burrendong Dam and a cease-to-flow date for the Macquarie River when introducing water restrictions in the current drought.

The director said the revised plan would aim to give the council more tools than the table.

"What we are trying to do with the plan is build some flexibility so that councillors have got the ability to make decisions around a range of scenarios," Mr Geddes said.

"So we don't want them to say here's a table and we only go onto this level if the table says so.

"We're saying let's look at things like inflows, take advice from WaterNSW and have quite a broad strategic review of the situation."

The council identified the key principles of the revised plan at Tuesday's event.

They include ensuring human health needs are met, prioritising community and business needs, giving certainty to business and sustaining liveability and a sense of place.
