Because corrosion is a major cause of costly water main breaks, Birmingham Water Works Board has used a corrosion inhibitor to minimize water corrosive potential. An applicability study for using alternative corrosion inhibitors, primarily-silicate based, has been identified and is being evaluated using a flow-through study. These results will be evaluated against the current inhibitor to see if a decrease in corrosion potential can be realized using silicate-based inhibitors. In addition to inhibitors, the impact of changing the primary coagulant change from aluminum sulfate to ferric sulfate, with its impact on metal leaching is currently being evaluated. Decreasing the potential for leaching metal from the distribution system is projected to have a positive effect on the reduction of main breaks and minimize corrosion.
