BBC television wildlife presenter Kate Humble has joined the campaign to educate Britons about the importance of water saving measures.

Figures published by the Department for Environment, Food and Rural Affairs (Defra) show that the average Briton uses 150 litres of water every day, compared to the 127 litres used by the average German.

It is estimated the water treatment process and the use of hot water creates 35 million tonnes of carbon emissions each year in the UK.

Ms Humble is now trying to get the message across that straightforward water saving measures can save money and help the battle against climate change.

"Simple changes can really add up to a better environment - meaning more water for the wildlife and countryside around us as well as saving on carbon emissions," she said.

Among the water saving measures recommended by Defra are turning the tap off while brushing your teeth and using a watering can instead of a hosepipe when watering the garden.

Waterwise recently launched a campaign to persuade people to spend less time in the shower, pointing out that an electric shower uses around six litres of water a minute.
