Author | Arantxa HerranzWater is vital for life on Earth, including human life. And, yet, fully immersed in the 21st century, 785 million people lack even a basic drinking water service according to the World Health Organisation, which also estimates that at least 2 billion people use a drinking water source contaminated with faeces, (which can transmit diseases such diarrhoea, cholera, dysentery, typhoid, and polio). To put this in perspective, contaminated drinking water is estimated to cause 485,000 diarrhoeal deaths each year.One of the United Nations Millennium Development Goals is for everyone to have access to clean drinking water by 2030. This is a considerable challenge since, according to its own figures, by 2025, half the world’s population will live in water-stressed regions.How can we ensure that drinking water reaches everyone and in a sustainable manner?
