What is, and why is water conservation important?
Water conservation is the preservation,
management, and care of water as a natural
resource. Of all the water in the world, only 3
is fresh. Less than a third of 1 of this is
available to humans. The rest is frozen in
glaciers or polar ice caps, or is deep within the
earth, beyond our reach. To put it another way,
if 100 litres represents the world's water, less
than a half of a teaspoon of it is fresh water
available for our use.

Current strategies around the home

• There are many reasons to save water in and
  around the home.
• It can help to reduce your running costs and
  spending less on water, energy and detergent
  bills, especially when it comes to washing
  machines, dishwashers, toilets and taps.
• These changes will also help the environment.
  These are all good reasons to save water.

Current strategies around the garden

• In Australia, about 35-50 of all domestic water
  use occurs in the garden. Most of our gardens
  contain plants inappropriate for our environment,
  and we often water far more than we should,
  because we dont know what our plants really
  need. As the driest populated continent on earth,
  we can't afford gardens that require excessive
  amounts of water. In the future new dams will
  need to be situated in more environmentally
  sensitive areas. This will be at the cost of tax
  payers, and may result in the destruction of
  wilderness areas. It will also degrade natural
  aquatic ecosystems.
• Water efficiency can reduce consumption, whilst
  retaining many of the plants we like. Efficiency
  should be a key concern when designing a garden,
  but it can also be incorporated into existing
  ones.

What we can be doing around the home

• When washing dishes by hand, dont rinse them
  under a running tap. If you have two sinks, fill
  the second one with rinsing water. If you have
  only one sink, stack washed dishes in a dish rack
  and rinse them with a pan of hot water.
• Use the minimum amount of dishwashing detergent
  (when washing dishes by hand) as this will reduce
  the amount of rinsing required.
• Use a plugged sink or a pan of water. This saves
  running the tap continuously.
• Use only as much water as you need in the kettle
  to cut your electricity costs at the same time.
• When boiling vegetables, use just enough water to
  cover them and keep the lid on the saucepan. Your
  vegetables will boil quicker and save you water,
  power and not to mention preserving precious
  vitamins in the food.
• Aerating taps are inexpensive and can reduce
  water flow by 50.
• Dont use running water to defrost frozen food.
  Ideally place food in refrigerator to defrost
  overnight.
• Where convenient and appropriate try to capture
  warm-up water for use on plants, rinsing
  dishes, washing fruit and vegetables, or other
  cleaning tasks.
• Check for leaks and if there are any dripping
  taps, replace washers or other components as
  required. Dripping taps can waste 30 200 litres
  of water per day, so ensure taps are turned off
  properly.

What we can be doing around the garden

• Xeriscape (xerosdry, scapeland) is a term often
  used for water efficient gardens, and targets
  seven basic areas planning, soil care, selection
  of plants, lawn care, irrigation, mulching, and
  maintenance. When applied together these
  techniques reduce water dramatically, however
  each technique on its own will have a significant
  impact. The concept was first developed in North
  America, but has since emerged as a generic,
  holistic approach for water conservation in the
  garden. The average garden hose delivers 1000
  litres of water an hour!
• We can be water efficient just by changing our
  behaviour. It is important to make sure that we
  apply it sensibly. Using trigger operated
  nozzles, checking for leaks in the hoses and
  taps, and remembering to turn off that hose left
  under the lemon tree are all simple ways to be
  water efficient. See the advice section for more
  information.

Conclusion

• Water is precious. As we can see, we all need to
  conserve water, and there is lots we can all be
  doing in the home, in the garden and at work.
• Do your bit now!
