General water news

This is Seek a Leak week!  Leaks can waste of lot of water when they go unnoticed.  Most leaks can be spotted by just taking a look around for things such as dripping taps, leaky toilets, and broken sprinkler heads.  But some leaks are harder to find especially if they are underground. 

Our online leak detection tool is a simple and handy way to find out whether you have a leak in your home.  It’s available at https://www.watercorporation.com.au/leaks
