The Rehabilitation and Maintenance of Drains and Sewers

This is the shortened, English-language version of the German volume published in 1989 and omits those contributions and passages that refer only to German laws, or which have little relevance outside Germany. It includes additional texts, especially on the relevant European norms and the canon of the Abwassertechnische Vereinigung [German Waste Water Technology Association] as well as the latest research and development reports. The result is a comprehensive overview of the technology currently available for wastewater management and systems plus the relevant norms, with special emphasis on maintenance, cleaning, inspection and reconstruction. A number of European systems are used to describe in detail pipe materials and connections, pipework-specific framework conditions and their changes since the development of modern drains and sewers in the 19th century. The book also lists causes and effects of various types of damage, and their assessment in terms of hydraulics, environmental relevance and construction, since this is a basic prerequisite for the choice of suitable rehabilitation measures and their implementation. Readers are thus not only provided with a comprehensive presentation of all internationally practised rehabilitation processes and their fields of application, but are also given advice on their selection, on the formulation of tenders, cost and cost efficiency.
