RELIABILITY LEVELS IN WATER TRANSPORT AND DISTRIBUTION NETWORKS DUE MAINLY TO CORROSION

Abstract

The spontaneous phenomenon of metal’s corrosion could be limited, controlled by o good corrosion management, which could be a rigorous application of accumulated knowledge or innovation. The diversity of each urban water system, the physical-chemical properties of water, soil, air and metallic materials, rule to a continuing development of nonconventional methods. The statistical analysis of data for a whole year, connected with the number of failures, at different elements of the cold water network, due to corrosion, could bring important information for a further reliability modelling, in order to a establish an improvement in the policies of energy efficiency increasing.
