Residential and non-residential/ commercial lawns cannot be watered with town water under level four restrictions starting on November 1.

High water users including "all schools" are being contacted by Dubbo Regional Council.

Its staff are notifying them of current level three water restrictions and the requirement of preparing a Water Saving Action Plan (WSAP) for implementation when level four restrictions begin in less than two weeks.

"Schools are one of the highest water users within the local government area and although council values the importance of a green lawn to play on, we are focussed on conserving the town water supply for the whole community," the council's chief executive officer Michael McMahon said.

"Council has stopped watering over 80 of its own open spaces and council assets to reduce the demand on the available town water supply."

Mr McMahon said council staff had been working with schools which had sought help in completing their WSAPs.

"We haven't received any resistance from schools to the incoming restrictions," he said.

"The schools that have been in contact with council have been very cooperative with the restrictions."

A Dubbo mother contacted the Daily Liberal when she learned of the water restrictions impacting school playgrounds.

"A lot of people who are following the restrictions don't have grass at home," Karen Cole said.

"We're relying on our kids having that green grass at school now."

The Dubbo resident contends schools would not have been impacted if the community had adhered to water restrictions from the start.

"I've heard of people using double the amount of water when level two restrictions began," she said. "Some gardens and lawns are greener than they have ever been."

Mr McMahon said the council-owned Rainbow Cottage day-care centre had become a "leader" in adhering to the restrictions and adopting water-saving practices.

"Simple ideas" such as encouraging kids to half-flush their toilets "when they can", reporting leaking taps, turning taps off after using them and converting gardens by planting drought-tolerant plants are being employed, he says.

Rainbow Cottage has also installed flow restrictors to reduce the pressure of water coming out of taps.
