Winter sprinkler switch-off

In WA, fresh water is a precious and limited resource. And climate change means it’s more important than ever to save water for when it’s needed most. In winter, we can let nature water our gardens and switch our sprinklers off to make big water savings.

Property owners in Perth and elsewhere across the southwest are required to observe the Winter Sprinkler Switch-off which runs throughout winter from 1 June to 31 August every year. Whilst the switch-off is mandatory for all scheme and bore water users in Perth, the benefits to your hip pocket and to your garden make it a great idea for properties outside of Perth too. So, we urge you to reduce your sprinkler use in winter and bank the water savings for the hotter months.

Why do I need to turn my reticulation off in winter?

The cooler temperatures and lower evaporation rates in winter mean your plants don’t need as much water. Most lawns also go dormant over winter, making it a good time to switch-off and bank that water for later. So, it makes sense to save some water in winter and reduce your water bill, so that you have a little up your sleeve in summer when your gardens and lawns need more water.

What if I don’t switch-off?

The switch-off has been a permanent water saving initiative in WA since 2010, and when everyone does their bit we bank significant water savings that can be used for the warmer months that follow.

Anyone in the Winter Sprinkler Switch-off area spotted using their sprinklers between 1 June and 31 August risks a $100 fine. And whilst the switch-off is only compulsory in some areas, it still makes good sense for all property owners to follow the guidelines. Using precious water when you don’t need to is just wasting your money.

If I have a rainwater tank – can I still use my sprinklers?

The Winter Sprinkler Switch-off does not apply to reticulation systems that use water collected by rainwater tanks. It only applies to scheme and bore water users in Perth, and other parts of southern WA. However, everyone is encouraged to reticulate only when necessary, regardless of the source.

What if my reticulation controller malfunctioned?

If your controller has malfunctioned, you may end up using water you didn’t need to. This will result in a higher water bill. It is your responsibility to check your reticulation system  – especially after events like a power blackout.

We urge you to check your controller regularly and reduce your sprinkler use in winter to make sure you are banking the water savings for the hotter months.
