Change to garden bore water restrictions

News Update 17 August 2022

From 1 September 2022, the domestic garden bore sprinkler roster will be changed to align with the two-days-per-week sprinkler roster for scheme water users in Perth and Mandurah, reducing from three days per week.

This is in response to climate change and rebalancing our groundwater use with reduced rainfall.

Alignment of the domestic garden bore and scheme water rosters will save up to 30 GL per year of groundwater, which will help to slow or reverse our declining groundwater levels.

Sprinkler rosters

A watering day roster applies to scheme and domestic garden bore sprinkler use in certain areas of the state.

Sprinkler roster days are based on the last digit of your house number. If you have no house number, use the lot number instead.
