Some of them have clean water, but it comes from WaterAid - A charity run by several water utility companies, including the one I work for. I get to see exactly how much of that money goes where and I can verify that the vast majority goes exactly where it ought to.
I did the WaterAid Ball a couple of years back.
They rented out and smartened up a knackered old warehouse that backed directly onto the Thames, with a lovely view of London.
They had Michael McIntyre as the MC and very cool he was. They had several current name entertainers like Justin Timberlake and Gareth Gates, fantastic 3-course dinner and a load of winable stuff.
You could go into the casino and get 20 chips for £200. £20 bought you a 1-in-5 chance of winning a lucky dip prize. £50 bought you one raffle ticket to win either a £21,000 diamond necklace or a Caterham Seven car!!
They also auctioned off loads of experience days, like lunch with famous sports people, sailing trips and so on. The biddings all started at £1,000. Someone paid almost 10 GRAND for a trip down the Thames Water Victorian sewer network!!
They got everything either free or at rock-bottom prices, with all the prizes being donated and I believe the entertainment was pro bono, too. The amount of money in corporate expense accounts that night was astounding and they raked in a fortune, ALL of which went directly to supplying and installing clean water and waste networks in the places that need them.
THAT is how a charity should be run!!
