Corrosion management in drinking water systems

Effective management of drinking water corrosion is crucial for ensuring safe and reliable water supply. This study highlights some of the challenges faced by water companies regarding biofilms in the distribution network, new materials and microbiologically influenced corrosion (MIC).
A practical case study is presented on the investigation and management of MIC in a stainless-steel pipe for drinking water in Denmark. The study involved a detailed analysis of the pipe's internal and external surfaces, identifying material degradation through a Multiple Line of Evidence (MLOE) approach. The findings highlighted the presence of MIC and how it was mitigated.
Finally, we provide a brief update on the application of EUR-WATER through COST, which aims to enhance water management practices across Europe. This initiative focuses on integrating advanced technologies and collaborative frameworks to address drinking water-related challenges effectively.
Highlights from this study:
• This study addresses the challenges faced by water companies and emphasizes the importance of setting up research programs through co-creation and collaboration. By involving water companies, consultants, researchers, and manufacturers in research, we aim to develop comprehensive solutions that benefit society and consumers.
• The urgency of this endeavour is heightened by global climate change, which exacerbates the need for water companies to deliver sufficient safe drinking water.
• Educating and training the next generation of water professionals is essential to sustain these above efforts.
