Copper pipe failure by microbiologically influenced corrosion
The failure of copper water service pipes by microbiologically influenced corrosion (MIC) in the water distribution system of the Brown Deer Water Utility, Wisconsin, was investigated. The characteristics of MIC were grouped into the categories of visual identification, piping configurations, and biological stability of the water. Greenish tubercles and areas of greenish film were seen on the interiors of the corroded pipes and pits were also found underneath the tubercles. Microorgasnisms were found to be active at the most distant locations of the distribution system where water stagnates, sediment accumulates, and disinfection residuals drop to low levels. Assimilable organic carbon (AOC) level in the distribution system were conducive to the growth of microorganisms and helped in the MIC influenced corrosion. A disinfection booster station, which was constructed and placed in operation in September 2004 has improved the distribution system.
