With world population growing, demand for food (and hence water for farming ) expected to grow by 70% ^[1], rivers becoming polluted and one in eight people already without clean drinking water ^[2], some have warned that we are heading for a 'peak water' crisis with people lacking the necessary water to survive, and wars breaking out over the access to water supplies ^[3]. Already, about half of all infectious disease is caused by contaminated drinking water.

A grim picture, indeed. But fortunately, an entirely avoidable one. Water is one of the most abundant resources available to us on this blue planet. The only problem we may face is synthetic scarcity; this article aims to show that there is no real shortage of water, nor of techniques to purify and manage it. If we simply apply the water-management techniques — many of which are extremely simple, low-tech, low-cost things — we have all the water we could ever need.
