Water really is the stuff of life. From washing to drinking and from the rain lashing against winter windows to the waves crashing against summer-holiday shores, it affects everything we do, and that’s before we even begin to consider how important it is to the rest of the planet. In Britain, of course, we’re all a bit spoiled when it comes to water; turn on the tap and there it is – but it isn’t quite as simple for many of the rest of the world’s population and around the globe, getting access to clean water is a major struggle for many people.
