Your watering days are determined by the climatic conditions in the region you live. 

Scheme water users in Perth, Mandurah and towns south of (and including) Kalbarri and Kalgoorlie can use their sprinklers once on their watering day, either before 9am or after 6pm 2 days per week based on the last digit of your street number. If you don’t have a street number, use your lot number instead.

Use the street number of the building if you live in a villa or an apartment.

Residents in towns north of (and excluding) Kalbarri and Kalgoorlie can use sprinklers every alternate day, watering once either before 9am or after 6pm based on the last digit of their house number. If you don’t have a street number, use your lot number instead.

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 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. We'll send an inspector to investigate.

Garden bore water users in Perth and Mandurah have the same watering rosters and times as scheme users. If you live outside these areas, your watering roster and times may differ. To check your watering days, enter your postcode into the box above.

Water is a shared resource that we need for our natural environment and public open space. So, it's important we use this resource carefully - sticking to our watering days is one way we can all do this.

If our inspectors see a bore user not following the roster, we pass it on to Department of Water and Environmental Regulation. The department may issue an infringement.


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.
