Clean Freshwater is a scare and vital resource here on Planet Water (that should be the name, rather than Planet Earth, as water is vital for life as we know it). Most people are trying to save water to save money, but it is hard to know whether its worthwhile. If we could all save and reuse water there would be less need for expensive dams and water supply devices such as desalination plants. These water capture and storage systems are bad for the environment.
So what water saving methods are worthwhile, and how much of a difference to they make? The images below show what a typical family of four (2 parents and 2 children) uses water on.
The Figure shown below shows the water use pattern of a typical American household. It highlights that more than 50% of the water is used for washing - showers, dishwashers, washing machines. Australian families used much more water on their gardens and lawns - as is shown in the tables below. These are the main useage areas where savings can be made.
One way of exploring your water use and seeing what impact various will make is using a calculator. You can do the calculations on various websites. You can also download an Excel version of the same tool from the same site. Another version is available here. Below is a summary of typical water use before savings applied, and after the major saving have been implemented.

The First Table above shows calculated water use for a typical family of two adults and two children. It shows that most of the water was used for the following purposes:
Applying the various savings shown in the second table produced a total reduction of more than half - from1139 litres per day to 500 litres per day.
Figures in the Second Table show that most of the savings occurred in:
This summary shows that relatively small changes can produce substantial water saves.

Become a Water Wise Advocate in your Community - Encourage your associates and friends to be part of a water-saving and aware community. Encourage your friends, co-workers and neighbours to do their bit. Like the water drops falling into a river it all adds up and if the whole community becomes involved the savings can become very effective - we can't rely on Governments - Water Authorities have a vested interest in keeping us wasting water.
Install rainwater tanks in your backyard - A rainwater tank of various size and design can capture and store many thousands of litres of water each year. It is a great way to teach you that water is a scare resource and that its supply is variable. Use it on the garden, for drinking water (if its not polluted by the roofing materials or the atmosphere), or for the grey water
Reuse your grey water - Whether you use the simple 'bucket' or drain-hose procedure to collect grey water, or have an entire grey water system established, reusing precious water assets can substantially decrease your water use.
Buy Water-Conserving Appliances - New appliances for example washing machines and dishwashers have water use labels on them that let you know how much water they use. Modern appliances are much better than the old ones.
Check Everything for Leaks - This applies to valves, taps, pipes, swimming pools and dishwasher hoses. Leaks are a surprisingly large source of water loss and plugging the leaks is a good way to save on your water bill. Remember, one simple dripping tap can waste you more than 2,000 litres every month. To do a basic check - turn off every tap and appliance in your house. Then read your water meter and wait for an hour of so, or overnight if you can, and read the meter again. If the meter shows a higher reading, there 's a leak in your house somewhere. The first place to check are dripping taps and your toilet. The washers are easy to replace.

Watering your garden in the cool of the early morning rather than in the hot part of the day. This is better for the plants and uses less water.
Lawn care - A good soaking at long intervals is best as it encourage deep roots and reduced water needs. When mowing the lawn keep the grass longer than about 2cm or an inch. Higher level grass also holds and retains water for longer. Let your lawns turn brown during dry spells in summer as they will recovery when it rains again. Remember that most lawns uses more water that your garden.
Don't wash paths, driveways, or patios down with water.
Keep planted areas dense and multi-layered which helps water retention. Sparsely placed plants dry out much more quickly.
Adding mulsh, organic matter and compost improves both the soil moisture retention of the spoil and nutrient availability.
Water pot plants by soaking them for several minutes in a laundry tub or a bucket of water. The water will soak up through the roots and water the plants much more efficiently,keeping the plants healthier. You will use much less water doing it this way.
Modify your watering schedule for the season and rainfall patterns and events to minimize over watering.
