Water Conservation- Needs and Methods

Water is a simple liquid that is of great importance for human life and sustenance. Water is a very large part of our lives.  In fact, 57% to 75% of our body is made out of the liquid. Water is very important for everyone living in this world, and to imagine life without water is impossible. There are about 1.4 billion people who don’t have access to clean drinking water, in the world of 6.8 billion people, 20.59% don’t have clean drinking water.  Obviously, water is a huge part of our daily lives and without it, you cannot live. Our daily activities are so much dependent on water that we cannot even live without water for a single day. We use water for many purposes such as drinking, washing, bathing, cleaning and agricultural purposes. Water is essential for life and it is very important to save water.
It is simply impossible to imagine human life without water, if there are no ample sources of water left then it would be a matter of great concern. Without water the will be no harvesting, no drinking water, no washing, cleaning and cooking as well. Hence it is very important to use our present water sources judiciously and try to save as much water as possible. It is very important to realize water conservation benefits and also to implement those in our day to day life. Water conservation encompasses the policies, strategies and activities to manage fresh water as a sustainable resource, and efforts to protect the water environment while maintaining a balance between current and future human demand. Population, household size and growth and affluence all affect how much water is used. Factors such as climate change will increase pressures on natural water resources, especially in manufacturing and agricultural irrigation. It is very important to realize the need for water conservation in the community as well as personal level.
Over the past few years a rapid growth in populations, modernization, growing industrialization, and expanding agriculture has pushed up the demand for water in the urban as well as rural areas. Human demands are increasing day by day but the natural resources are in a limited quantity. Efforts have been made to collect water by building dams and reservoirs, practising rainwater harvesting, digging wells; some countries have also tried to recycle and desalinate salty water to make it fit for drinking or washing. Water conservation has become a major need of the hour. The idea of groundwater recharging by harvesting rainwater is gaining importance in many parts of the world and has been practised successfully in many parts of the world.
Needs and Importance of Water Conservation
Water is an essential part of human life and plays a major role in human sustenance. We use water for drinking purpose, cooking, washing, for producing electricity, for farming, for industrial purpose and many other purposes that support the human lifestyle. Earth is about 70% water, but there is only a small amount of groundwater source that is fit for drinking and cooking purpose. Ninety – seven per cent of all the water on the earth is salt water which is not suitable for drinking. Only three per cent of all the water is fresh water, and only one per cent is available for drinking water. The other two per cent is locked in ice caps and glaciers. About 70% of the water source that is from the sea and oceans the major part contains saline water that is the salt level of this water is so high that it cannot be used for drinking purpose and purification process for this water is really high. Our water supply is finite, which means that we do not have an endless supply.
We only have the water that we have now. The adult human uses on average about 100 gallons of water a day which may seem to be a small figure but with the rising population and depleting water sources there is a fear that one day there will not be enough water sources available to meet even drinking demands. Seawater that is highly salty as a result is not fit for human consumption and not even for industrial purpose or for producing electricity. Since this water contains a high amount of salts, therefore, using this water in industries and for producing electricity leads to salt deposition on the machinery and this at times can get really dangerous and lead to some major industrial disasters. Hence sea water is of no major use for humans.  
As we discussed earlier that water resources are finite and there is only 3% of freshwater sources, with all the people on Earth relying on such a small percentage of all the water on Earth, it only makes sense that we must preserve and conserve our water for our own survival otherwise a day will come when all the water sources will be extinguished. Besides conserving water it is also important that we must not pollute our water sources because it is the only water we will ever have. There are a lot of people who do not realize the importance of water, and they are continually wasting and polluting it. Only about ten per cent of wastewater is disposed of properly.
It is a high time that we must start saving water today so that it will be available to us in the future. We need to think of future generations, if we go on wasting our water resources recklessly then it is obvious that in future we will not have a sufficient supply of water unless we become more concerned with how we use our water today. There are many things that we can do to help preserve water. These are not things that are hard. All it takes is a little bit of extra effort, and soon it will be second nature. Save the water, that’s all we can do.
Methods of Conserving Water
The most important step in the direction of finding solutions to issues of water and environmental conservation is to change people’s attitudes towards the fact and also changing habits which include each one of us to put in some sincere efforts. Conserve water because it is the right time to do so. We can follow some of the simple things that have been listed below and contribute to water conservation.
Every drop of water counts, so make sure you are not wasting clean drinking water and you are not leaving any running tap.
Remember to use only the amount you actually need and not wasting the water unnecessarily.
It has been found beneficial to form a group of water-conscious people at school, college or society level and encourage your friends and neighbours to be part of this group. Promote water conservation in community newsletters and on bulletin boards. Encourage your friends, neighbours and co-workers to also contribute.
Plant more and more trees to increase transpiration.
Encourage rainwater harvesting at the community level as well as municipal level.
Make sure that your home is leak-free and there are no leaking taps or tanks storing water. Many homes have leaking pipes that go unnoticed. Call a plumber as soon as you notice any leakage.
Do not leave the tap running while you are brushing your teeth or soaping your face.
When washing the car, use water from a bucket and not a hosepipe which helps to reduce about 50% of the water used for washing your car.
While watering your lawns do not waste water and use only the amount that is required.
Do not throw away water that has been used for washing vegetables and use it to water plants or to clean the floors.
