[2] One day back in 2007,he was sitting in a friend’s house and noticed a leaky tap.It bothered him.A few days later, he came across a statistic in the newspaper:a tap that drips(滴落)once every second wastes a thousand litres of water in a month.That triggered an idea.He would take a plumber(水管工)from door to door and fix taps for free every weekend.

[3] He named his Non-governmental Organization ‘Drop Dead’and created a slogan: save every drop…or drop dead.

[4] By the end of the first year,he had visited l,533 homes and fixed around 400 taps.Slowly,the news began to spread.Local newspapers began to write about Drop Dead, which caused a further flood of grateful emails and messages.Conservatively, it could be estimated that he has saved at least 5.5m litres of water till date.
