Frequently asked questions

Yes, you can. Our inspectors are out in force 7 days a week and all complaints are investigated, with $100 on the spot fines issued for breaches of watering rosters.

Remember – you should only water once, either before 9am or after 6pm on your allocated watering days.

If they have a bore, they’re allowed to water 3 days a week, once a day either before 9am or after 6pm. If they don't have a bore, then they can water 2 days a week.

If you suspect a watering breach we encourage you to report it using our sprinkler breach form or contact our waterwise helpline on 13 10 39 and we can send an inspector to investigate.

Yes, while you get an extra watering day, sprinkler rosters and times apply to bore water users as well. Most garden bores draw from our precious shallow groundwater resources. These are shared resources that provide water for our natural environment, public open space and other users. So, it’s important we use this resource carefully – sticking to our watering days is just one way we can all do this.

If our inspectors catch a bore user not following the rosters, we pass it on to Department of Water and Environmental Regulation who may issue an infringement.

The State Government has announced a proposal to align Perth and Mandurah garden bore users' sprinkler roster with the scheme sprinkler roster (two watering days per week). This is in response to the impacts of climate change and increasing groundwater use. To learn more and have your say, visit the Department of Water and Environmental Regulation's website.

The watering days roster uses your street number, so you don’t need to worry about your personal apartment or villa number.

For example, if you live at Unit 1, 22 Water Street, you should use 22 in the watering days search. If your property spans multiple street numbers, like 22-24 Water Street, you use the higher of the numbers to find your rostered watering days. So in this instance, you would use 24 in the watering days search.

Temporary water restrictions are short term measures imposed in times of drought or emergency in order to reduce demand and conserve water supply for essential needs. Water restrictions specifically target non-essential uses, such as garden irrigation. Water Corporation requests a temporary water restriction be enacted through the Minister for Water so essential needs are met.

Permanent water efficiency measures (PWEMs) are in place to ensure best practice for the efficient use of outdoor water use. They include the sprinkler watering rosters which are ongoing, rather than temporary. These measures were introduced in WA in October 2007 after a trial and extensive consultation. They are established via regulation administered by the Department of Water and Environmental Regulation, and enforced by Water Corporation.
