Exclusive: £75m publicity drive will ask people to treat water as precious resource and cut daily use by 28 litres

The biggest ever campaign to encourage the public to reduce their water use will launch this week, as the UK emerges from record temperatures attributed to the climate crisis.

The £75m publicity drive, called Let’s Save Water, will advise and encourage people to treat water as a precious resource and has a target for everyone to cut their daily use by 28 litres – or two large buckets – from the current average use of about 140 litres a day.
