New Delhi - Thousands of flushed condoms threaten to choke the Commonwealth Games village's drainage system, media reports said, in the latest problem to hit the venue from hidden snakes to outbreaks of dengue.Games organisers, who won a race against time to ready the village, are now battling to clear clogged drains after thousands of non-biodegradeable contraceptives were flushed down toilets in the first week of the event."If that is happening, it shows that there is use of condoms and I think that is a very positive story. Athletes are being responsible," Commonwealth Games Federation President Mike Fennell told a news conference on Thursday."We all know that encouraging safe sex is a very important thing to do."Games organisers had provided 8 000 free condoms in the village, and the provision appears to be in high demand. One official told the Mail Today newspaper on Thursday that over 4 000 had already been snapped up by eager athletes.Shoddy construction work, fears over an outbreak of dengue fever and worries about security had meant many teams delayed their move into the village before the Games began. However, blame for the latest problem lies firmly with the athletes.Following a decision to provide free condoms at the 1992 Olympics in Barcelona, it has become something of a tradition.At the Sydney Olympic Games in 2000, athletes quickly used up the 70 000 free condoms provided, forcing organisers to supply another 20 000, while at the 2004 Games in Athens, the provision was doubled to 130 000.At both the Beijing Games in 2008, and the Vancouver Winter Olympics in February, 100 000 condoms were provided for athletes.
