Save Water: Reduce Your Water Footprint
People use lots of water for drinking, cooking and washing but even more for producing things such as food, paper and cloth.
A water footprint is an indicator that looks at both the direct and indirect water use of an individual, business, community, city or country.
Direct water use refers to the water we see coming out of the tap: the fresh water we use each day for drinking, cooking, showering, washing dishes and clothes, and gardening etc.
Indirect water use refers to the water that is used to manufacture the goods that we consume or produce, and the services that we use, as well as all of the water that is made unusable by pollution or wasted by non-use. That includes all of the water used to grow the food that we eat eat, to produce the things we use in daily life — clothes, books and furniture — and the water needed to produce the energy we use.
While this indirect water is «invisible», we often use far more of it than we realise.
In Europe, for example, the average person directly consumes between 100-150 litres of water a day — as drinking water, for washing clothes, bathing and watering plants.
But each person also indirectly consumes anywhere between 1,500 and 10,000 litres of per day, depending on where they live and their consumption habits.
Measuring water footprints can give us a clear picture of how water is used in today’s society, and help us come up with strategies for more sustainable water usage.
Some Facts and Figures About Water Use
- Water covers 70.9 percent of the planet’s surface.
- 97 per cent of the that water is salt water.
- Around the world, 2.1 billion people still lack access to safe water.
- Water use is growing at twice the rate of population growth. Unless this trend is reversed and we come up with a way to share water fairly and sustainably throughout the planet, two-thirds of the global population will face water “stress” by 2025
- In the USA , the average water footprint per year per capita is as much as the water needed to fill an Olympic swimming pool, an average of 7,786 litres of water per person per day.
- In China, the average water footprint is 2,934 litres of water per person per day.
- In the Netherlands, 95 per cent of the water footprint of consumption lies somewhere else in the world (due to the amount of imported goods consumed), whereas in India and Paraguay only 3 per cent of the national water footprint of consumption is external.
- It requires around 1500 litres of water to produce 1 kilogram of wheat, and a huge 10 times more to produce the same amount of beef.
- The water footprint of a cup of coffee is around 140 litres, a cup of tea only around 34 litres.
Your Footprint Calculator
The Water Footprint Network website offers an online calculator which estimates your personal water footprint, based on your country of residence and your patterns of consumption:
How to Reduce Your Water Footprint
Broadly speaking, you can reduce your direct water footprint by:
- turning off the tap while brushing your teeth
- using water-saving toilets
- installing a water-saving shower head
- taking shorter showers
- only washing your clothes when necessary
- fixing household leaks
- using less water in the garden and when cleaning
- not disposing of medicines, paints or other pollutants down the sink.
When it comes to reducing your indirect water footprint, there are a number of different approaches you can take.
The food we eat makes up a huge part of our personal water footprints, and implementing some of these changes could have knock-on benefits for your health too. Examples include:
Eating less meat. Beef is one of the most water-intensive proteins, needing 15,000 litres of water per kg, followed by red meats in general. Other, less water-intensive proteins include pulses like beans, lentils and peas. Chicken has a much lower water footprint than beef, so if you’re not ready to become vegetarian or vegan just yet, giving up or just cutting back on red meat can help.
Switching coffee for tea. Cups of tea and coffee may look like they contain the same amounts of liquid, but producing coffee beans requires far more water than growing tea leaves, around 140 litres for a cup of coffee and around 34 litres for tea.
Cutting down on sugar. Drinking a bottle of cola actually consumes around two or three bathtubs full of water. Growing sugar cane uses a lot of water (and often water-polluting pesticides too), not to mention the water that goes into producing plastic packaging.
Eating less processed food. Water is required at every stage of food production — refining, processing, canning, packaging. Eating fresher food means consuming less water, sugar, salt, preservatives and chemicals.
Consuming more local produce. Producing a tank of petrol requires a lot of water, so reducing the amount of miles you food has to cover from farm to plate will also help save. And your food will be fresher and more rich in vitamins too. Win-win!
Buying quality, not quantity. The clothes we wear use huge amounts of freshwater. Cotton fabrics and denim jeans are particularly greedy. Buy well-made clothes that are intended to last, rather than huge amounts of cheaply-produced items that will need to be replaced. The same goes for any other consumer product, as practically all manufactured products — from electronics to books and cosmetics — consume water in the production process. Buying less will protect the world’s water supply and your wallet.
The responsibility for cutting back on water consumption shouldn’t just lie with consumers, of course. For people to be able to make informed decisions about which options to choose, businesses need to be transparent about their processes, and governments more forward-thinking when it comes to regulation. When information is available on the impacts of a certain article on the water system, consumers can make conscious choices about what they buy. And if governments were to bring in water-saving measures, businesses would be incentivised or perhaps even obligated, to introduce water-saving measures.
More Tips for Saving Water at Home
Install a foot tap. Rather than using the traditional, ubiquitous twist-knob taps, you can install a foot pedal which you press to control the flow of water. Using such pedals helps reduce water consumption by as much as 50 percent.
Attach a shower head to tap fittings. Installing a shower head on your tap might sound a bit strange, but trust us on this one. It is a common misconception that high-pressure, high-volume water is needed to clean tough dirt and grease from dishes. In fact, what is more effective is using a wide water spray rather than heavy water volume which of course can be achieved through the use of a shower head. Fitting a water-saving showerhead to your tap will still give you enough water and spray to clean effectively, meaning you use less water even when washing the tough stuff.
Bring a bucket. A peek into any bathroom in Australia provides a handy water-saving tip from the inhabitants of the driest continent on the planet — place a bucket in the shower. These buckets are placed under the showerhead to catch all that excess water that normally goes down the drain while you wait for the water to heat up.
Treat your wastewater at home. Generally speaking, all that water that trickles down the drain after you use it can actually be a boon for the garden. Commonly referred to as wastewater (or blackwater and greywater), leftover water from the bathroom, kitchen and laundry is mixed with detergents, oil and dirt and is generally not appropriate for use in the garden in its waste form. However, with proper filtering and treatment it can be highly beneficial for crops. Treehugger has some resources here on how to reuse greywater in your home and garden.
Use eco-friendly cleaning products. Using biodegradable cleaners (i. e. natural items such as lemon, tea tree oil, baking soda and vinegar) as well as phosphate-free detergents also helps to reduce water consumption and is less harmful to the environment. Using them to clean uses less water than chemically-laden alternatives. One reason for this is the inclusion of Sodium Lauryl Sulfate (SLS) in many conventional cleaning products. SLS is generally used as a foaming agent, its foaming properties triggered when coming into contact with water. These agents also need to be washed off any surface or item after use considering the harmful impact they have on human health. Compare this to using vinegar, which requires no water to offset it’s disinfecting properties and doesn’t need to be washed off a surface or item after it’s been used to clean (check out this site for the ultimate list of do’s and don’ts when it comes to cleaning with vinegar).

Why is Water Important
Why is Water Important :
- Water is one of the most important substance required to live on Earth
- Our Mother Earth will not exist without water
- Water is used in day to day life for many purposes other than drinking
- Without water, we human beings will die
- Water is required for all living things in the world
Why is Water Important : (Short Essay)
Water is one of the most important substances that are needed for plants and animals. We cannot lead our day to day life without water. Water makes up more than half of our body weight. Without water, all organisms in the world would die. Water is necessary not only for drinking but also for our day to day life purposes like bathing, cooking, cleaning, and washing and so on. We cannot imagine a life without water. Other than drinking and household purposes, water is important for existence of our world. Conservation of Water is important for our goodness and for the future to come. We need to take initiatives to save water whether there is scarcity or not.
Why is Water Important : (Brief Essay)
Every organism in the world needs water. From tiny insects till blue whales, every life on Earth exists with the presence of water. A plant needs water to grow and stay fresh. A whale needs water as a place it lives. We human beings require water for our day to day life. The reason for necessity of water might different from organism to organism. But the very existence of the world is ensured with the amount of water available in the world.
Cells in our body will not function properly without water. We need water either taken directly or through fruits or vegetables that have some water content in them.
Water is needed in great amount for us to:
- Drink for survival and digest the food you eat
- Washing our clothes and things
- Clean vessels and home, and so on
Moreover, to get healthy fruits and vegetables, we need plenty of water for the plants, trees and crops regularly.
Water is a very crucial substance which at the same time is scarce. Though we see lot of water in the oceans around the continents, the truth is we cannot consume sea water from the oceans. Only 3 % of world’s water is in a form we can consume. The resources of fresh water are:
- Excavated Dams
- Soil which has lot of fresh water absorbed in
- Under Rocks
With much scarcity of water and high necessity of the same it becomes so important that we need to undertake conservation programs for saving water.
