"Hot, dry weather and a lack of rain has resulted in a significant drop in river levels activating a reduction in the amount of water council is permitted to take. This means that we are unable to meet the current level of demand from the town supplies."
The council implemented water restrictions in December in an attempt to avoid having to place more severe restrictions as summer ramped up.
"The forecast for a drier than normal summer has come to pass and there is now an immediate need for communities to conserve water and abide by the total hosing ban."
The total hosing ban will be in place until further notice. Updates will be shared on the council's website and Facebook page, and announced via local radio stations.
Additionally, posters will be delivered to the central business districts in the affected towns.
