The AWWA C653-20 standard provides guidelines for the disinfection of water treatment plants. It specifies the materials and procedures necessary for disinfection, addressing the needs of both newly constructed treatment facilities and existing facilities that are temporarily taken out of service for maintenance or other activities that may contaminate the water.

The standard primarily focuses on chlorination as the disinfection method, outlining the requirements and considerations for its use. It covers various treatment components such as filter basins, filter media, clearwells, pump suction wells, and associated piping and appurtenances downstream from the filter influent or the first point of disinfectant application.

The purpose of this standard is to ensure the effective disinfection of water treatment plants to maintain water quality and prevent the introduction or spread of bacteria, viruses, and other contaminants. Compliance with the AWWA C653-20 standard helps to ensure safe drinking water for consumers by providing clear guidelines for the disinfection process in water treatment plants.
