LETTER : Leaky argument

From Dr Brian Betram

Sir: Your report on water leakage from the mains ("Leaks waste 826 gallons of water a day", 4 August) quoted Thames Water as saying that a tap dripping once a second wastes 10,000 gallons a year.

For that to be true, all those drips would have to be the size of marbles. Have Thames Water lost theirs?

Yours faithfully,

Brian Betram
