The purpose of this standard is to define the minimum requirements for the disinfection of water-storage facilities, including the preparation of water-storage facilities, application of chlorine, procedures for disinfecting underwater inspection and cleaning equipment, and sampling and testing for the presence of coliform bacteria, chlorine residual, and acceptable aesthetic water quality. This standard can be referenced in specifications for the disinfection of waterstorage facilities and can be used as a guide in preparing water-storage facilities for disinfection procedures following inspection or maintenance.
