We often take the availability of water for granted. Water is a renewable resource, but its availability in a form readily usable for drinking and other domestic and industrial purposes is being placed under increasing stress as we use more and more. During periods of drought in particular, groundwater and reservoirs supplies can become significantly diminished. The following points illustrate just how much water we consume in the UK, and how we could attempt to reduce this level of consumption.
- We use around 155 litres of water each day on average, which is 70% more than 30 years ago. That’s around 1600 pints of water a week each.
- Running the tap can use 10-14 litres of water a minute – which would give enough for a small bath in just 5 minutes.
- Make sure you mend any dripping taps, and turn off taps when not in use.
- Turn off the tap when brushing your teeth.
- Take showers, not baths and save enough water each week for 1000 cups of tea.
- A garden sprinkler uses 1,000 litres of water an hour – that’s nearly one pint for every 2 seconds it is in operation.
- Once a week is all the water your lawn needs even in the hottest weather. Over-watering can weaken your lawn by encouraging roots to seek the surface.
