Australian water crisis facts

Here's some interesting water facts and stats you may not be aware of:

  • Australia's rainfall is the lowest of all continents in the world (excluding Antarctica). Despite this, Australia has one of the highest per capita water consumption rates in the world.
  • While two thirds of all the 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.
  • If everybody in metropolitan Melbourne cut just 1% of their yearly water consumption, there would be enough water saved to fill 2,500 Olympic size swimming pools.
  • As of the time of writing:
    • Sydney's available water storage is approximately 38%
    • Melbourne water storage levels are at approximately 30%
    • Brisbane water storage levels are at approximately 20.5%
    • Perth water storage levels at approx 21.3%
  • Our major cities are on the following water restrictions:
  • CSIRO modelling predicts that global warming will cut future rainfall in southern Australia by up to 20 per cent.
  • A 4 minute shower uses approximately 35 Litres of water. 7 showers per week per year adds up to around 13,100 Litres of water for each person in the household.

Bidegradable Detergents - Greywater Detergents

Here's some great info on choosing detergents that are suitable for use in Grey Water systems from the SaveWater website. So far I'm yet to find a simple, but comprehensive guide to choosing a greywater friendly brand name detergent. Every Australian site I've come across point to the Lanfax Labs website but the information there seems to be hidden amongst a lot of scientific research.

If anyone's found a user list of biodegradable and greywater friendly detergents, let me know and I'll post it on this site.
