Our winter sprinkler switch off applies to all scheme and bore water users in Perth, Mandurah and some parts of the South West and Great Southern from 1 June to 31 August every year.

During the winter of 2019 we saved around 5 billion litres of water by switching off our sprinklers.

Climate change means it’s more important than ever to save water for when it’s needed most.

Winter brings with it cooler temperatures and lower evaporation rates which means the plants in our gardens don’t need as much water. Most lawns also go dormant over winter, so you can leave your sprinklers off and let the rain take care of your lawn and garden instead.

The switch-off prevents water waste, saving it for our drier months. This enforced ban has been a permanent water saving initiative since 2010. Anyone in the winter sprinkler switch off area found using their sprinklers between June and August risks a $100 fine. Our inspectors are out in force 7 days a week and all complaints are investigated.

Please note:

  • We advise that you check your irrigation system after a power black-out. If you need to test your irrigation system, following black-outs, repairs or installation, please visit the testing your irrigation page to find out when you can undertake the testing and what you need to know.
  • If you have installed a new lawn or garden you need to apply for a watering exemption to use your sprinklers during the switch off.

Frequently asked questions

You can apply for a watering exemption to use your sprinklers during the switch-off. Keep in mind that you will need to meet the conditions applicable to your exemption or be at risk of a fine up to $500. Breaches are the responsibility of the property owner, not the person who installed the lawn, plants or sprinkler system.

The Winter Sprinkler Switch-off does not apply to irrigation systems that use water collected by rainwater tanks. The switch-off only applies to scheme and bore water users in Perth, Mandurah and parts of the South West and Great Southern regions. However, we do encourage everyone to irrigate only when necessary, regardless of the source.

You might be surprised to know that the switch-off also applies to licensed groundwater users including local governments, schools, golf courses, government departments, universities, TAFE campuses, major parks, race grounds and businesses that irrigate areas of non-commercial turf, lawn and gardens.

The exceptions to this are active sporting locations, such as schools and local government ovals, which are permitted to irrigate during winter due to their frequent use, safety considerations and amenity planting.
