A new survey has revealed that the “vast majority” of Brits have no idea how much water they use each day - 46% believe their household uses under 20 litres a day when the true figure is closer to 142 litres per person per day.

A further 17% believe they consume between 20 and 39 litres a day while 15% think they use 40 to 59 litres

The research was carried out on behalf of Water UK, the trade body which represents all of the major water and wastewater companies in the UK and Waterwise, an independent not-for-profit campaigning organisation, and the leading authority on water efficiency in the UK.

The average person in the UK uses 142 litres of water a day compared with 121 litres in Germany - the two organisations have now joined forces to call for more to be done to educate the public about their water use.

To help people understand the amount of water they use, water companies want government to do more to embed water efficiency in the national psyche.

They are calling on government to use the Environment Bill to introduce water efficiency measures, such as labels on washing machines and dishwashers to show how much water they use, and smarter building regulations to cut water waste.

The misconception is most acute amongst the young with 66% of 18-34-year-olds believing their household uses under 20 litres. However, the lack of awareness continues throughout the age groups with a quarter (26%) of over-65s answering the same.

However, while people are unsure about the amount of water they consume, the vast majority (68%) say they are willing to reduce the amount of water they use at home to help protect the environment.

The results of the poll by Savanta ComRes, which surveyed 2,190 UK adults online between July 31 and August 2 2020, also revealed:

35% of UK adults say they try to save as much water as possible with 12% saying they don’t try to save any

• 63% of UK adults say they always turn the tap off when they brush their teeth
• 42% of UK adults are worried about parts of the UK running out of water in the next 25-years

The impact of the Covid-19 outbreak has put increased pressure on water supplies. With many more people staying at home combined with a surge in the number of ‘staycations’ has meant demand for water has been exceptionally high this summer.

As a result of the unique circumstances Water UK and Waterwise launched launched the ‘Water’s Worth Saving’ Campaign earlier in the summer - a joint initiative to help the public save water.

The campaign, which builds on the existing awareness raising work of water companies, aims to educate consumers about the water they are using while offering simple hints and tips to help save this precious resource.

Water UK Chief Executive Christine McGourty commented:

“The results of this survey illustrate the importance of our Water’s Worth Saving campaign to show the public the value and importance of saving water.

“It’s been a typically unsettled British summer, but we’ve also seen periods of very hot weather in parts of the country. This combined with more people at home and the surge in ‘staycations’ has seen record levels of water demand and has put huge pressure on supplies.

Managing Director of campaign group Waterwise, Nicci Russell, said:

"Waterwise believe that water should be used wisely every day, in every part of the country and whatever the weather.

“We hope that the results of this survey, alongside the Water's Worth Saving campaign will help the public better understand and value water.

“By making small changes such as turning the tap off when brushing your teeth or swapping a bath for a short shower, you're not only helping to save water but energy, money, as well as protecting the environment and future supplies.”
