The evidence suggests that Londoners make use of an average of 165 litres of water every day, higher than the nation's average of 150 litres and about one-third greater than other European cities.
These must be disheartening figures for just about any British household, but you need not panic. By enlightening yourself about conserving water in simple ways, you can breathe easy and possibly even use a hose or sprinkler to water your garden in the end.
Water is used in the home in a number of ways and the biggest water use in most homes will be using water for cleansing the body with the figure indicated as 45 percent.
Since there is a need to cleanse ones body not only to feel good but for health reasons as well how can water be conserved. Which is better for our environment? Having a Bath or a Shower?
So firstly, here are the facts for the amount of water used for both:
A full bathtub holds approximately 140 litres of water
Standard shower heads dispense 20-60 litres of water per minute
Shower heads with flow restrictors dispense 10-15 litres of water per minute
It is believed that an average bath requires 100 to 200 litres of water. For a shower depending on your showerhead and whether it has a flow restrictor in it and how long you shower, the answer could fluctuate either towards shower or bath. The average shower of four minutes with an old showerhead uses 80 litres of water. With a low-flow showerhead, only 40 litres of water is used.
If your house was constructed before 1992, chances are your showerheads force out about 20 litres of water per minute. Multiply this by the number of minutes you are in the shower and the litres add up fast!
So apart from the issue of the amount of water used when bathing and showering there is another environmentally concerning issue which is the amount of Carbon Dioxide used.
It would appear that the bath comes out the clear loser in this case as a typical bath uses around double the amount hot water as a five-minute shower, and therefore uses twice as much energy and emits twice as much CO2 to heat the water.
Simply a Local Plumber can fit a great new shower and it should not cost the earth.
All water usage demands energy, since the water has to be purified and pumped from the mains, but hot water uses the most energy of all, therefore the less water we use, the greater energy we save.
We believe from the evidence that bathing is more costly to our pockets and to the environment. Our solutions and what can be saved by trying it:
Reduce the amounts of baths and start getting familiar with the shower. I everyone in the UK swapped one daily bath for a five minute shower could save enough water for the needs of 15000 households.
If you had a shower instead a bath once weekly 30kg of CO2 emissions may very well be saved.
Are there any other water-saving devices? Yes there are. When your water is heated by a combination boiler or direct-feed thermal store, an effective flow-restricting device can be fitted to your shower hose. These are generally available from various suppliers. They are easy to fit without needing to turn the mains water supply off, but aren't suited to power showers or electric showers.
If you have an electric shower, when it needs to be replaced fit the lowest-rated one you can find. An 8kW shower wil use allot less water and energy than a 10kW one.
Your plumber will know allot about saving water and therefore can advice you on the right device for your home.
