At what concentration is a new main line super chlorinated?

Super chlorination of a new main line typically requires a concentration of chlorine that effectively disinfects the pipeline, ensuring that any potential pathogens or impurities are eliminated. The choice of 50 mg/L as the appropriate concentration reflects best practices in water treatment, especially when dealing with new infrastructure.

Chlorine at this level ensures a robust disinfection process, which is critical for maintaining water quality and safety. This higher concentration is specifically chosen for its ability to penetrate biofilms and disinfect surfaces within the main line thoroughly, thus reducing the risk of contamination.

Public health standards and water quality regulations often stipulate such measures to safeguard community water supplies. Therefore, utilizing a concentration of 50 mg/L for super chlorination aligns with industry practices established for effective disinfection of new water mains.
