After Perth's wettest winter in 30 years, its dams aren't anywhere near full – and Water Corporation wants consumers to know why.

It's an important question that affects everyone in the Perth area, so Water Corporation and ABC News have collaborated on a story that explains the answer in detail.

Plumbers around Perth can help Water Corporation educate consumers about the ongoing need to conserve water simply by sharing this link to the story.

In simple terms, it's the result of climate change. According to Water Corporation, if everyone in Perth leaves their sprinklers off in September, we can collectively save three billion litres of drinking water. That’s equivalent to three Optus Stadiums full of water – so encourage your customers to keep sprinklers turned off until they are really needed.
