Water use has been growing globally at more than twice the rate of the population growth in the last century. We may face a water shortage if this growth continues. Are you thirsty? What can you do? A person drinks about 3 to 4 liter's of water a day. But the average person actually uses much more than that. A ten minute shower uses about 143 liters of water. A low flow shower uses about 87 liters in the same amount of time. reference: www.youtube.com/watch?v=GOLf2RbxmzE |

Water conservation is the preservation, control and development of water resources, both surface and groundwater, and prevention of pollution.1
As water is one of the most important things we need to survive, wasting it by leaving the tap on the get the right temperature water isn’t the safest thing to do as the world is running out of fresh water as there is only less than 1 percent of water on the earth left. 2 Although salt can be removed by machines it is an expensive procedure that is rarely used. The best thing that we can do is learn to conserve the water. At the moment in Australia we conserve water by; • Having a water container in the fridge for when you want to have a cold drink instead of running the tap to get a cold drink. • Only using the washing machine and dishwasher when they are full so that the water doesn’t go to waste with lots of small loads. • Leaky taps that drip slowly can waste up to 20,000 litres a year • Putting hoses and sprinklers on a timer so water isn’t wasted 1 stats.oecd.org/glossary/detail.asp?ID=2903 (26/08/16)2 www.livestrong.com/article/119446-need-conserve-water/ (26/08/16) www.natureaustralia.org.au/celebrating-australia/water-saving-tips/ (26/08/16) |

According
to about lake mono, water conservation is
the most-effective and environmentally sound way to reduce our demand for
water. It stretches our supplies further and protects place like lake mono.
Fresh
water is the most precious thing on earth because one it is important
ingredient for living things on Earth. We use water in everyday living by
either drinking or eating; we use it for energy and for transport. Water covers 3 quarter of the Earth, 1% of
fresh water gives life to so many things is taken for granted.
·
400 billions of water is used
everyday
Most of the world’s usable freshwater is
underground
Hoekstra and Chapagain have done a study of how
much water is used. According to them
Australia is terrible at water conservation. On average, each
Australian uses 341,000 litres of water each year that’s around 8 backyard
swimming pools. Australia is the most light-hearted water uses
in the planet; Australia is also the driest continent on the planet. The worlds average water wastes is 57,000
litres.
20% of water in the world in

In Australia, which is the world’s driest consentient it is important that we conserve water. What we could do to improve our water levels is simple, we could lower our water use by use things such as flow controls for taps and waters, water efficient products, improved irrigation and improved irrigation control systems. We could also use alternate water supplies, E.g. rain water, bore water and grey water. The water bore I use works off an aquifer, if you don’t know what an aquifer is use my web link reference. I think that bore systems work well because it is a renewable resource of water as it ‘recharges’ after being used, but this can only happen with some aquifers. water.usgs.gov/edu/earthgwaquifer.htmlMax, I think that your suggestion of using 'flow controls' is a great suggestion, especially for household taps and irrigation for our gardens. However, there is likely to be additional expenses for the general homeowner introducing these into their homes.
If Australia is focused on conserving water via reducing our usage, should the homeowner be expected to pay for the installation of the flow controls? What other options could be introduced?

Water conservation is an environmental method in order to reduce the usage of water. In today’s society, the use of water is used carelessly because it is so accessible everywhere however; this is not the case for developing countries because it is hard to find fresh water and countries that do not receive a lot of rain also have to deal with the constant struggle of having water restrictions. In Australia, we currently conserve water by having water tanks because they naturally collect rain water. This has ineffective outcomes on states and territories that do not produce a lot of rain because it will cost money to install and further takes up space on the citizens’ properties. Water conservation was a major issue that occurred especially within the states of southern Australia. The water restrictions were placed in order to preserve the amount of water usage within the southern states because there were major drought issues. I believe that Australia needs to have conserve water, especially within states that are dealing with droughts and that do not produce a lot of rain because that means they have to enforce water restrictions to reduce the usage of water. The Northern Territory is currently the main providers of water because it naturally produces rain yearly but the rain produced each year varies. There are issues for not conserving water in Australia because it can affect the environment and the economy. If Australian’s use water carelessly, it can drain the natural soils that depend more on water than we do and droughts ruin the natures land and the scenery it provides. Conserving water has positive results for Australia because we commonly deal with droughts and it is good to preserve the water we have instead of using it and ending up with water restrictions which has economic effects on citizens because they have to pay fines if they do not obey the restrictions.

You made the statement that 'In Australia, we currently conserve water by having water tanks because they naturally collect rain water. This has ineffective outcomes on states and territories that do not produce a lot of rain because it will cost money to install and further takes up space on the citizens’ properties.' If water tanks are ineffective in a number of other states/territories, what alternative options are there? And do these alternative options come with a high price tag?

This is in use in Victoria Vic, Vic, Vic, Victoria Desalination the process of removing salt, esp from sea water so that it can be used for drinking or irrigation 11 www.thefreedictionary.com/desalination Abdul, desalination is an effective process in some areas of Australia, and across the world. You have complete a lot of research on water conservation, and provided the forum with a lot of information. Now you need to start discussing your thoughts and opinions on the water conservation topics.
For example. Would a desalination plant be beneficial in the Northern Territory? Would the cost of building it, be worth the final outcome of an additional water supply? Would the Northern Territory Government be likely to increase current costs of water for residents?
Just some suggestions to consider.

The Earth's population will continue to grow, and so will the need and access for fresh water. What options do we have in Australia to reduce current water usage? Do these options really work? How can we educate Australian society to use the options?

Whilst we can all make suggestions about how we can conserve water in our home, do we really do it??
What are the current education / marketing strategies used in Australia for water conservation? Are these really effective?
As a young person, how do you think you could effectively educate other young people to conserve water?

Raelene, you have presented some eye opening facts associated with water usage (or misuse).
I'm interested further in your reference of Hoekstra and Chapagain's study, and that 'Australia is terrible at water conservation. On average, each Australian uses 341,000 litres of water each year that’s around 8 backyard swimming pools'. Why do we waste so much water? What strategies or options can be put into place to reduce our wastage of water?
Please remember to cite all of your references.

Every living element needs water to survive, therefore water is one of our most important resources. Water conservation means using less water or recycling water which can be used again. Water conservation is important because it helps save energy, prevents people from using too much water that cannot be replaced with rain and also helps people and governments save money. We advertise ways to save water here in Australia on television ads, ads on social media, on posters and by sending emails. We also try to get the message across verbally; by volunteering around schools and at public events. We are all able to save water and reduce water wastage by doing simple acts around the house; by regularly checking leaks and fixing them, installing water-efficient dishwashers, replacing single-flush toilets with dual-flush toilets, limiting shower time to under four minutes and much more household activities.

I think that bore systems work well because it is a renewable resource of water as it ‘recharges’ after being used, but this can only happen with some aquifers. water.usgs.gov/edu/earthgwaquifer.htmlThanks for this link max. Lots of interesting information there. It's important to remember that groundwater only recharges when it rains - when a dry season is particularly dry the bore will be depleted; two or more very dry seasons will seriously impact it. Groundwater like all water on earth, originates from rainfall.
Water that is not used by vegetation filters through the soil
until it reaches the saturated zone. This process is called
groundwater recharge. Significant recharge can be expected
only during rainy periods. The water table (level) in an aquifer
will rise and fall depending on annual variations in rainfall/
recharge. Aquifers can also gain water from rivers and streams
draining into the ground.1 The same site provides this summary: Groundwater Facts
1. 22% of the world’s freshwater is groundwater;
2. 90% of the NT’s water supply is from groundwater;
3. The NT has approximately 35,000 water bores;
4. Groundwater is affected by long term climatic cycles; and
5. Over use of groundwater poses a significant risk to
springs, soaks and rivers.2

I found a great site about domestic water use: www.angelamorelli.com/water/It will only take a few minutes to look through it and it is quite startling. The author is Angela Morelli who is based in Oslo, Norway - not a place with immediate water problems, but it is known for its long-term planning. According to this site domestic water use (ie not including food production, manufacturing etc) is 137 litres per person per day. In Australia it is rather more, on average. In Victoria during the most recent drought people were asked to reduce their daily water use to 155 litres per person 1, and water bills showed each household's average daily use over the billing period. It was a hugely successful campaign: the majority of households did reduce their usage and the average went below the target. I assume that the difference in usage (137 vs down to 155 litres) might be because of the preferred lifestyle of many Australians of a house with a garden - in places where apartment living is the most common (this includes Oslo) the watering of a garden isn't a factor.
