Pipe Material Selection in Drinking Water Systems

New environmental water quality directives and increasing demands on pipe performance have focused attention on design criteria and selection of pipe materials for drinking water distribution systems. Water quality changes during distribution and the different pipe materials (and their degree of corrosion) are linked. Other factors in the selection of materials such as physical strength, pipe construction, laying technology, joint methodology and the external environment of the pipe must also be considered. These proceedings comprise 14 papers selected from the 3rd international seminar that aimed to bring a holistic perspective to the issue: amongst the topics covered are internal corrosion, microbiological activity, water treatment and corrosion control, pipe material selection case studies, and external corrosion and structural design. The seminar provided a very successful forum for water supply professionals, corrosion scientists, pipe designers and manufacturers and engineers. The state of the art contributions selected for these proceedings set out current experience and strategies for pipe material selection from a holistic viewpoint.
