How to Reduce Your Water Footprint

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).
