Muswellbrook and Denman will be on Level 1 water restrictions from July 1.
The restrictions are in place in a bid to encourage water to be used sustainably as the Upper Hunter continues to suffer from drought.
At the moment Glenbawn Dam is sitting on 51.4 per cent capacity and with below average winter rainfall forecast for the area and the country Council has agreed to adopt the restrictions.
Muswellbrook Shire Council has said that while there isn't "an imminent water shortage it is conscious of, and sensitive to, ongoing drought conditions and possibly an extended bushfire season and wishes to encourage the community to use water effectively and sustainably".
"In addition, neighbouring rural areas are facing potable water shortages and Council, in partnership with local Lions Clubs, is supplying free water to be carted to farming families to top up domestic water tanks. In order to support these measures Voluntary Level 1 Water Restrictions have been adopted."
The decision is also on the back of collaborative consultation through the Upper Hunter Water Alliance group with Muswellbrook Shire, Upper Hunter Shire and Singleton Councils.
There will be moratorium on enforcement of the restrictions in place for any one caught misusing water from September 1, 2019.
Upper Hunter Shire Council will be looking to adopt the same Level 1 water restrictions at their Council meeting next week.
Singleton's Level 1 water restrictions are in place from July 1.
