The major problems caused by internal corrosion in drinking water distribution systems are structural damage, reduction of hydraulic capacity and water quality deterioration. The nature of corrosion can be chemical, elektrochemical or microbiological. As drinking water is an electrolyte solution, in metal pipes the electrochemical corrosion might be predominant which is generally characterised by Eq. (1H3) and Fig. 1. The microbiological corrosion in distribution systems is governed by biofilms accumulated on the internal surfaces. Certain micro-organisms can utilise the redox potential of corrosion for their
