Even in the temperate region of Britain, the elements still shape our lives - mostly as a result of drought and deluge. This book looks at the issues concerned with water consumption and usage including the use of water in power stations. The book looks at what we need to know about geology and weather, about the politics and economics and the chances of flood or drought. Furthermore, as water supply is not simply a public service but also a vital national resource, each of us needs to know how the system works, which changes to encourage and which to fight.
