A water tank is a moveable container for capturing and storing rainwater and household grey water such as water from washing machines. Consumers can use water tanks to transport water for use on gardens or cars, for example. Due to drought conditions across Australia, an increasing range of water tanks is available, including:
units that resemble giant buckets ranging in capacity from 90 litres upwards
models with locking devices or instructions for consumers to secure the lid by using a screw or tek-screw
units advising consumers to secure the lid with a screw or tek-screw, without locking mechanisms.
It only takes a few centimetres of water for a child to drown. Investigations have found that water tanks with an overall height of up to one metre with an easily removable lid would not prevent children climbing inside the water tank and drowning.
