At WaterAid we love talking about toilets. So we were thrilled when, last year, the UN officially created a day to recognise the importance of sanitation: World Toilet Day. This year, you really pulled out the stops to help us spread the message that toilets save lives. From spending the day dressed up as a toilet to becoming a Sanitation Superhero and building a giant loo - around the world, you made sure everyone was talking about one thing: toilets. See the best bits from World Toilet Day 2014 here > It's no joke We know talking about toilets can be hard. So in the run-up to World Toilet Day, we used comedy to help the nation overcome their embarrassment. We gathered some of Britain's best-loved comedians and launched our It's no joke! competition, to find the UK’s top toilet joke. Now the votes are in – and you can watch the country's favourite funny, courtesy of comedian Bec Hill, below. Urine for a treat! Want more laughs? Watch the rest of the wee-one liners from our potty-mouthed comedians here > One of the world's most neglected issues This year's World Toilet Day may have had its fair share of fun, but for millions of people around the world, sanitation is no laughing matter. Our latest report, Child of mine, shows just how neglected the issue is, and how devastating the consequences can be. Right now, one in three children does not have access to a basic toilet. As a result, ten million under-fives have tragically lost their lives since 2000. We can't let this continue. That's why WaterAid, together with international health and development experts, has sent an open letter to Ban Ki-moon, Secretary-General of the United Nations, calling on him to end the crisis that has left so many people without access to this most simple of provisions. Help us make sure change happens. Share our Child of mine report with your MP > "The thing that can help the community is good water and improved latrines," says Carlinda. The lack of these basic provisions means many members of her community in Niassa, Mozambique, suffer from diarrhoea, which can be fatal.

We work with our local partners to deliver low-cost, sustainable solutions. We also campaign tirelessly to demand that governments target their development efforts and spending on sanitation. It might not be sexy or nice to talk about, but we know that toilets save lives. Even more than that, spending on sanitation has huge economic benefits – for every £1 invested in sanitation and water, there's a return of around £4. Health is improved, fewer days are lost to sickness, and children, especially girls, stay on at school longer.
