Description: An essential reference book for all engineers, planners and designers involved in constructing or maintaining drainage works. Some 32 000 properties could be at risk of flooding from sewers in the next 10 years. As well as being a key issue for the owners and occupiers of those properties, it is one that has important implications for sewerage undertakers and the water industry regulator, Ofwat. This book shows that, in many cases, the solutions need not involve expensive major works aimed at increasing overall sewer capacity. The installation of anti-flooding devices, for example, or making use of better storage capacity in the system may prove just as effective. It guides the user through the choices available, provides detailed criteria for selecting suitable options for each type of flooding problem and gives typical costs for each option. Clearly written, with useful checklists and cost comparisons.

Keywords: urban drainage, pollution prevention, sewerage, flooding.
