The sound of condensation dripping inside a rain-water tank almost seems luxurious in the face of global freshwater statistics.

According to http://water.org 884 million people around the world lack access to safe drinking water. Every day 24,000 children under the age of five die from diseases contracted from unclean water. In developing countries 80% of discharged sewage is untreated – global biodiversity is dropping most quickly in freshwater ecosystems.

The United Nations declared that water use has grown at more than twice the rate of the global population in the last 100 years. By 2025 an estimated 1.8 billion people will be living in areas of extreme water scarcity. Socio-political conflicts have already begun to occur over the ownership of fresh water, such as between Malaysia and Singapore in 1997

In Australia, the driest continent on earth, access to fresh water is extremely limited yet we have one of the highest per capita water consumption rates in the world. WWF states that while two thirds of all people on Earth use less than 60 litres of water a day, the average Australian uses more than twice that amount during a single shower.
