The Effect of Copper on the Corrosion of Iron Watermains

The data obtained from several municipal watermains corrosion studies in the Province of Ontario is presented. This data corroborates the findings of a previous study indicating that the galvanic couple formed by the connection of the copper service piping to watermain is a principal factor controlling the watermain corrosion rates. Soil electrical resistivity is found to be of major importance where this galvanic couple exists. A simple means of estimating the integrity of a watermain based on soil resistivity and service type is also presented.
