Watering Days Perth

       With greywater every day is a watering day laughing

If you live in Perth or Mandurah, or some parts of the south west, and you are on scheme water, you can only use your garden sprinklers two days per week. If you have a bore you can use your sprinklers three days per week. There is also a permanent Winter Sprinkler Ban which applies to both scheme and bore water users from 1 June–31 August every year.

The days you can use your sprinklers is determined by the last digit of your street number. If you live in a villa or apartment use the building number. This page was last updated 22nd June 2019. Refer to the Water Corp website for details.

Of course if you have a greywater system you can use it seven days a week all throughout the year if you like! This is arguably the greatest benefit of owning a greywater system – it allows you to keep your garden green and productive all year round and even in times of drought and water restrictions.

Towns north of (and excluding) Kalbarri and Kalgoorlie can use sprinklers every alternate day between 6pm and 9am based on the last digit of your house or lot number.

Garden bore users outside of Perth and Mandurah can use their bore between 6pm and 9am.

I love using Grey water in my garden because it allows me to minimise the use of scheme water in our garden watering regime with only small changes to the type of cleaning products we use in our laundry and bathroom. It also allows me peace of mind every time I take a shower knowing the water isn’t just going down the drain but directly into my beloved garden.

Having Greywater go to my garden means my plants get watered every day of the year when I’m home. The water savings in summer are huge. Installing a greywater system at my own new build was a must, along with a Rainwater tank. Putting these systems in during the build process is easy compared to retrofitting, and generally cheaper. ‘Water Capture’ sell, install and service Greywater systems in Perth.

WaterCraft service a lot of greywater systems across the metro area and see many gardens thriving on the use of greywater. Frequent watering with traces of soap and nutrients works really well for plants on poor sandy soils. But just as you wouldn’t expect your mains water retic system to run for years without any attention, don’t expect your greywater system to keep running without a service!
