Corrosion Control in Sewage Water Systems

The mechanism of material degradation in sewer pipes is similar to potable water systems. The internal corrosion may be more severe than in potable water because the wastewater is not clean. The winterizing treatments of roads are a source of chloride, which comes into contact with the pipe. Cement-based pipe experiences corrosion of reinforced steel. The corrosion control method consists of using thicker pipe walls, which provide for larger corrosion tolerance and a longer design life. 

8 Optimized Management by Combining Corrosion Control Methods 

To prevent any further problems in the cases where lead and copper release is the problem, it is advisable to consider the complete replacement of the tubes, fittings, fixtures and joints by corrosion-resistant components. The most commonly used repair methods for water systems with corrosion damage are given in Table 4.35.
