I READ with interest the story featuring Matt Le Tissier about saving water (Daily Echo, March 18).

On thinking about the claim that having a three minute shower will save 23 million litres of water in Southampton alone, I did a few calculations. The city has a population of about 222,000, so even allowing for every man woman and child having a daily shower (which I doubt), 23,000,000 divided by 222,000 gives a water saving of 103.6 litres (about 20 gallons) per person per day.

How was the published figure calculated and by whom?

I am getting increasingly irritated by wildly inaccurate statements being bandied about all in the name of saving the environment.
