Werris Creek will move to level 2 water restrictions from Wednesday due to the ongoing drought.
This will mean residents will no longer be able to use sprinklers at any time of day and drippers and hoses can only be used between 6pm-8pm.
Those with pools over 2000L must have a permit to fill them, and top-ups are via hoses only, for two hours per day.
Water supplies at Quirindi, Wallabadah, Willow Tree, Spring Ridge, Caroona, Premer and Blackville will be on level 1 restrictions.
Liverpool Plains Shire Council mayor Andrew Hope said the continued dry conditions made it "important for consumers to be water wise to conserve what water we have".
"With longer range forecasts predicting extended drier than average conditions there is no room for complacency," Cr Hope said.
"If everyone is responsible and abides by the restrictions, consumers will be contributing to extending the life of their water supply that will continue to dwindle until substantial falls occur in the catchment areas."
The council's water services manager Rod Batterham urged residents to "protect this vital asset to forestall the need for even tougher restrictions".
"Everyone is urged to abide by the restrictions and where possible to take other steps to conserve water. The restrictions being implemented now are not onerous," Mr Batterham said.
"If we are forced to go to level 3 restrictions, use of sprinklers, drippers and hoses is banned and use of buckets is restricted to 6pm to 8pm. Level 4 and 5 restrictions would see no watering at any time, no washing down of outside areas or vehicles at any time, and no filling or topping up of pools."
Mr Batterham also said any property in the shire with a town water connection planning to use an alternative water source such as rainwater or private bore supply outside the restrictions must apply for a Water Management Plan and display the sign issued by the council at the front of their property.
