What standards are typically used to disinfect a water tank?

• A. NSF 61
• B. Universal standards
• C. AWWA standards
• D. ASME standards

Answer: (C)

The correct answer is based on the standards set by the American Water Works Association (AWWA), which are widely recognized in the water industry for their focus on the safety and quality of water supply. AWWA standards specifically address the design, construction, maintenance, and disinfection procedures for water storage facilities, including tanks. These standards guide water distribution operators in ensuring that disinfection processes are effective in eliminating pathogens and other contaminants, thereby securing public health. In the context of water tank disinfection, AWWA provides detailed protocols that cover the necessary procedures and concentrations of disinfectants to be used, ensuring compliance with health regulations and promoting safe drinking water. This is essential because disinfecting water tanks is vital to preventing microbial contamination and maintaining the overall integrity of the water distribution system. The other options, while related to standards in different contexts, do not specifically address the disinfection of water tanks with the same specificity and applicability as AWWA standards. NSF 61 focuses on health effects and safety of materials used in drinking water systems. Universal standards are not formally defined for water tank disinfection and can vary greatly. ASME standards are more relevant to mechanical engineering and pressure vessels rather than water quality or disinfection processes.
