Awwa Standards Free Download: Ensuring Sanitary Conditions in Water Storage Facilities

Premise plumbing components in buildings often utilize a diverse range of materials that may not be compatible with the chlorine concentrations specified in this standard. This article aims to provide an overview of the importance of adhering to AWWA standards for disinfection in water storage facilities.

The American Water Works Association (AWWA) has developed guidelines for the disinfection of potable-water-storage facilities, which are crucial for maintaining sanitary conditions and ensuring the safety of drinking water. The standard is designed specifically for tanks within public water systems and does not apply to storage tanks located within premise plumbing systems in buildings.

In certain situations where rigorous sanitary procedures have been followed, only sampling may be required. In other cases, the tank may remain in service or isolated for minimally invasive activities such as ROV or diver inspections. However, when performing highly invasive activities like painting, repairs, or maintenance tasks that require dewatering, storage facilities must undergo disinfection and sampling procedures to prevent contamination.

The standard also outlines procedures for disinfecting underwater inspection and cleaning of potable-water-storage facilities. Additionally, it includes guidelines for preparing new storage facilities before placing them in service, which involves disinfecting the facility to ensure sanitary conditions.

In summary, the AWWA standards for disinfection of water storage facilities provide a comprehensive framework for maintaining sanitary conditions and ensuring the safety of drinking water. By understanding these standards, water treatment professionals can take steps to prevent contamination and ensure that their facilities meet the necessary requirements.
