Which method is used to mitigate corrosion in water distribution systems?

• A. Increasing water temperature
• B. Adding chlorine to the system
• C. Maintaining optimal pH and using corrosion inhibitors
• D. Reducing water pressure

Answer: (C)

The method of maintaining optimal pH and using corrosion inhibitors is essential for mitigating corrosion in water distribution systems because it directly addresses the chemical environment that contributes to corrosion. Water that is either too acidic or too basic can enhance the rate of corrosion on pipes and fittings, which can lead to increased maintenance costs and water quality issues. By carefully managing the pH levels, water utilities can create conditions that protect the integrity of the infrastructure. Corrosion inhibitors, which are chemicals added to the water, form protective films on the interior surfaces of pipes, reducing the interaction between the water and the metal of the pipes. This helps prevent the leaching of metals into the water supply and extends the lifespan of distribution infrastructure. The combination of optimal pH control and the addition of corrosion inhibitors is widely recognized as an effective strategy for managing corrosion, ensuring the safety and quality of drinking water, and maintaining system reliability.
