One drip per second can waste up to 12,000 litres of water from a single tap, per year. The most common reason for a leaking tap is a worn tap washer that can no longer create a tight seal. It is important to change worn tap washers as soon as possible to ensure we are not letting clean water go down the drain. Find out how to change a tap washer.

Each customer can receive one water saving showerhead. It can be hard to tell if you have a water saving showerhead, as some have the same shape as the old style. There is a simple test to see how much water your showerhead uses each minute: Our water saving showerheads are not suitable for low pressure (eg gravity fed), or instantaneous hot water systems. Greywater is water that has already been used in your house. Instead of letting it go down the drain into the sewer system, greywater can be captured and used in certain circumstances outside your home. Greywater is managed by councils, with each council having different regulations regarding the storage and use of greywater. As it has already been ‘used’ in your home, it is important to store and use it correctly to avoid the water-borne diseases we see in countries without adequate sanitation. There are a number of dos and don’ts when using greywater. For instance, it should not be used to water vegetables that you will eat raw, or during wet periods when it won’t soak into the soil.
