READERSHIP: This book is aimed at professors and students of civil engineering and at practising engineers and technicians in consulting firms and municipalities. NEED: Nowadays, we realize the importance of drinking-water distribution, rainfall collection, and sewage networks as urban infrastructures. They are expensive to install, but rehabilitation or reconstruction costs can even be higher. This book gives engineers and technicians in civil engineering modern tools and means to design water conduits with adequate capacity and to select materials and equipment that meet the needs of the population and of industrial and business communities. By following the methods described and applying modern standards of design and installation, urban hydraulic specialists will build infrastructures that provide better service. SUBJECT: This book covers five major subject areas. The first is evaluation of network flow rates and their variation over time; these are drinking-water and fire-protection flows; storm, sanitary, combined, and pseudo-sanitary flows; and so on. The second introduces rules and regulations for the design of different types of networks and the choice of equipment such as water intakes, street inlets, street-holes, fire hydrants, valves, and connections. The third deals with the dangers and diseases encountered when working in the water engineering fields. The fourth shows computations of loads on buried pipes. The last discusses the very important problem of how to design storm and sanitary sewage networks, two wastewater-intercepting sewers, and a water-distribution network. Each chapter has complete examples along with a set of exercises at the end. Answers are provided at the back of the book.No other book discusses water networks and the choice of related equipment in such detail.
