Abstract

Leakage of drinking water pipelines is becoming a major operational issue for many water utility companies all over the world. It is not unusual that the volume of Non-Revenue Water share reaches beyond 40% of the nominal capacity of the service provider. Having always been a considerable concern over metal structure deterioration, corrosion could gradually reduce those infrastructures’ life in service, badly affecting their primarily designed functions, and may even be more serious particularly in case of pipe distribution system in different soils and on the seabed. Once a tiny leakage appears, it will obviously be accompanied by product losses, environmental issues and in some instances, could be disasters. However, there have only been a few controlled studies which accelerated pre-localized dissolution of metal and intended to focus on comprehending the attenuation of iron pipes. To solve this problem, a controlled corrosion system was built to examine removed iron mass using some mathematical-physical laws, a rough estimation of pipe’s remaining strength is expected as well. Several sensible correlations were established, comparisons were made to filter out the indispensable factor regulating this phenomenon.
