This standard for disinfection of water-storage facilities describes materials,
facility preparation, application of disinfectant to interior surfaces of facilities, and
sampling and testing for the presence of coliform bacteria, chlorine residual, and
acceptable aesthetic water quality. The standard also includes disinfection procedures
for underwater inspection and/or cleaning of potable-water-storage facilities
but does not describe the technical aspects of underwater inspection and/or cleaning.
All new storage facilities shall be disinfected before they are placed in service.
All storage facilities taken out of service for inspection, repair, painting, cleaning,
or other activity that might lead to water contamination shall be disinfected before
they are returned to service. Major changes made in this revision of ANSI/AWWA
C652 are as follows:
several definitions have been added or updated;
addition of Sec. 5.1.1.5, Optional Sampling and Testing; and,
broad revision of Sec. 4.4.7, Post-inspection chlorine residual, turbidity, and bacteriological testing.
