Mitigating Pipe Corrosion in Water Distribution Systems: Strategies for Sustainability and Resilience

Abstract Submission: The corrosion of metallic pipes in water distribution systems is a critical issue that impacts the integrity and efficiency of water supply networks. This study investigates the relationship between environmental changes and the accelerated corrosion of these pipes, which can lead to increased water loss and a higher incidence of pipe failures. As global temperatures rise and precipitation patterns shift, the chemical composition of water and soil environments surrounding the pipes is altered, exacerbating corrosion processes. Changes in soil moisture and pH levels can intensify the electrochemical reactions that cause corrosion. Additionally, warmer temperatures and altered water chemistry can enhance the growth of biofilms and bacteria, including those that contribute to microbiologically influenced corrosion (MIC). One of the primary manifestations of this corrosion is tuberculation, the formation of rust nodules on the inner surfaces of pipes, which not only reduces water flow but also serves as a breeding ground for harmful bacteria. This research aims to summarize recent findings and best practices from literature publications to enhance maintenance strategies for water distribution systems. By examining the latest advancements in corrosion prevention, monitoring technologies, and maintenance protocols, we seek to develop a comprehensive framework that municipalities and water management authorities can adopt to mitigate the adverse effects of environmental changes on corrosion. Additionally, these efforts will help lower the carbon footprint of water distribution systems by reducing the need for energy-intensive repairs and replacements, making the practice more sustainable. This study underscores the importance of proactive corrosion maintenance and adaptive strategies in the face of evolving environmental challenges, ultimately contributing to the sustainability and resilience of water systems.
