Some interesting facts about water

  • Turning off the tap when you clean your teeth can save around 8 litres of water a minute.
  • A cubic metre of water weighs a tonne. That's about the same as a small car.
  • Save water by growing drought-resistant plants such as sedums and lavender, using a watering can rather than a hosepipe and watering early in the morning or in the evening.
  • We use an average of nearly 150 litres of water a day in our homes; our great grandparents managed with about 18 litres.
  • It takes about 450,000 litres of water to produce a small car.
  • UK water companies collect, treat and pump almost 18 billion litres of water every day, nearly a quarter of which goes down the toilet.
  • A garden hose or sprinkler can use almost as much water in an hour as an average family of four uses in one day.
  • One dripping tap can use at least 5,500 litres of water a year. Mending the tap washer could save you about £18 a year.
  • Overall, only 3% of the water entering the average home is actually used as ‘drinking’ water.
  • Trees are about 75% water.
  • Forestry Commission records show that almost 20% of trees that they inspected recently in the UK were damaged or killed as a result of drought during the long dry summers.
  • Our wetlands are drying out. A recent survey found out that over 70% were in an unfavourable condition.
  • Health experts reckon that we need 6-8 glasses of water every day to keep us fit and healthy (and aid our concentration).
  • A litre of bottled water can be more expensive to buy than a litre of petrol.
  • The dishwater v. washing debate: recent research shows that on average conventional washeruppers use 63 litres per session, and if they then rinse the detergent off under a running tap, this rises to 150 litres. A modern dishwater can use as little as 15 litres per cycle.
  • About a third of all the clean, drinkable water you use in your home is used to flush the toilets.
  • A bath can use up to 100 litres, a shower uses about a third of this. But beware - modern power showers can use more water than a bath if you shower for more than 5 minutes.
  • The average roof collects about 85,000 litres of rain in a year! This could fill 450 water butts with free water.
  • Most moisture is lost through the top 10cm of the soil in the first five days of hot weather.
  • Many people in the world exist on 10 litres of water or less. Some UK toilets can use that in one flush of the toilet.
