How often must chlorinator rooms have facilities to determine the amount of disinfectant used?

Chlorinator rooms must have facilities to determine the amount of disinfectant used on a daily basis. This requirement is crucial for maintaining water quality, as chlorine is the primary disinfectant used in water treatment to eliminate pathogens. Daily monitoring ensures that the chlorination process is effective and that the residual levels of disinfectant remain within safe and effective limits. It allows operators to make timely adjustments to the disinfection process, ensuring the water remains safe for consumption and helps in compliance with health regulations.

Other timeframes, such as weekly, monthly, or yearly, would not provide the necessary oversight to respond promptly to variations in water quality or changes in demand. Regular daily checks are essential for effective operation and to prevent issues that could arise from either under-dosing or overdosing of disinfectant.
