The GBP1.2 billion Cairo Wastewater Project was designed to remove water from one of the world's largest and fastest growing cities and treat it to a standard permitting re-use for agriculture. This issue of ICE Proceedings contains nine refereed papers that cover various aspects of the planning, design, construction and management of the project.

This book is the record of the conference held in Oxford in 1992 organised by CIRIA, and co-sponsored by the Health and Safety Executive, The British Tunnelling Society and the Medical Research Council's Hyperbaric Sciences Panel. The book consolidates international medical and engineering knowledge and experience on the use of compressed air and hyperbaric techniques, and looks to how they can be safely used in the future.

This book moves beyond superficial generalizations about Cairo as a chaotic metropolis in the developing world into an analysis of the ways the city's eighteen million inhabitants have, in the face of a largely neglectful government, built and shaped their own city. Using a wealth of recent studies on Greater Cairo and a deep reading of informal urban processes, the city and its recent history are portrayed and mapped: the huge, spontaneous neighborhoods; housing; traffic and transport; city government; and its people and their enterprises. The book argues that understanding a city such as Cairo is not a daunting task as long as pre-conceived notions are discarded and care is taken to apprehend available information and to assess it with a critical eye. In the case of Cairo, this approach leads to a conclusion that the city can be considered a kind of success story, in spite of everything.

Recording the history of John Taylor and Sons and their predecessors, Gwilym Roberts describes civilisation as a product of engineering. He demonstrates how dependence on technology goes back to the earliest civilisations, when irrigation systems enabled man to abandon a nomadic existence.
