If you’re a new homeowner or are new to Western Australia altogether, you may experience some initial confusion about your allocated watering days.

Here in Western Australia, we make a conscious effort to work together to preserve our precious water resources. Since 2001, we have had allocated watering days that are allowed to be supplemented with hand watering, combined they are sufficient in keeping local lawns and plants vibrant, green and healthy. By observing this rule, we manage to save an impressive 4.5 billion litres of water every year.

So, if you want more information about WA’s watering rules, we’ve done the hard work for you. Here’s everything you need to know about watering days and schedules right here in Perth.

Western Australia watering days

First things first, it’s important to ascertain your home’s allocated watering days according to your postcode and house number. To find this, head over to the Water Corporation website.

If your property doesn’t have a house number, instead use the lot number to determine your watering days.

Scheme and bore water sprinkler usage

In Perth, Mandurah and towns south of (and including) Kalgoorlie and Kalbarri, scheme and bore water users can use their sprinklers before 9am and after 6pm on their allocated days.

Watering times

In general, watering may only take place before 9am and after 6pm.

Sprinkler ban in winter

In WA, there’s a total sprinkler ban from June 1st to August 31st. If you are caught using your sprinklers between these dates, you could be handed a $100 fine.

Bore water watering days

Those with a bore are allowed an extra watering day every week. This fits within the allocated watering days for your residence.

Rules about hand watering

Though you’re able to water your garden by hand on any day of the week, it’s best for your garden to do so before 9am and after 6pm. This is because watering before 9am provides your garden a cooler climate, and helps keep evaporation to a minimum.


If you need to apply for a watering exemption for a new lawn or garden, you can do so by completing an online form on the Water Corporation website.
