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.

5
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!

Extension Activity!
  • We compared the water conservation strategies in
    a Melbourne Brisbane.
  • They have deep gutters.
  • They dont need tanks..
