Toilets. Water Closets. Dunnies. Whatever you call them, we all use them – but they’re not something we often talk about. And they’re definitely not a topic that you’d expect the Secretary-General of the United Nations to want us to discuss. Yet that is exactly what Ban Ki-Moon is encouraging us to do. Saturday 19 November is World Toilet Day, and breaking the taboos around loos is one of of the main goals of this global awareness campaign. According to the UN, there are 2.4 billion people around the world “struggling to stay well, keep their children alive and work their way to a better future – all for the want of a toilet.” At Oxfam, the humble toilet is a topic close to our hearts. Water and sanitation are a big part of our work and the installation of Fresh Life toilets has made a huge difference to the health and livelihoods of people living in poor places. The toilets also bring us closer to the Sustainable Development Goals target of access to a toilet for everyone by 2030. In the Bangladeshi slum of Horijon Polli, lack of access to clean toilets and fresh water is the reality for many residents. But this reality quickly turns to a nightmare when it rains. The drains that line the slum’s streets, often clogged with human and household waste, regularly overflow in the heavy rain. Polluted water floods the streets and people’s homes with raw sewage and rotting garbage.
