What is the substance used for disinfecting new water lines as required by the State?

The appropriate substance for disinfecting new water lines, as specified by the State regulations, is calcium hypochlorite. Calcium hypochlorite is widely utilized due to its effectiveness as a disinfectant in water systems, especially for new installations. It is available in solid form, which makes it convenient for handling and storage, while also having a high concentration of available chlorine that ensures a strong disinfection process.

When calcium hypochlorite is added to the water, it releases chlorine, which effectively kills harmful bacteria, viruses, and other pathogens that may be present. This is critical in maintaining water quality and ensuring public health safety as the new pipes are introduced into the water distribution system.

While chlorine gas, sodium hypochlorite, and potassium permanganate are also utilized for disinfection, they have different applications, handling requirements, and characteristics compared to calcium hypochlorite, making calcium hypochlorite the preferred choice specifically for disinfecting new water lines.
