The review copy will be edited for publication and may also be revised as appropriate based on any comments received during the public comment period. Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.

Final publication of the standard may take several months. When it is available, a notice will be published in the official notice section of Journal - American Water Works Association. The standard becomes an effective AWWA standard on the first day of the month following such publication in Journal - American Water Works Association. 

SCOPE
This standard describes sacrificial anode cathodic protection systems intended to minimize corrosion of interior submerged surfaces of steel water storage tanks. This standard does not describe automatically or manually controlled impressed current systems. 

MAJOR REVISIONS
Major changes made to the standard in this edition include the following:
1. Language regarding dissimilar metals inside the tank below the  maximum water level (MWL) has been added (Sec. 4.1.1). Related commentary has been added to Sec. A.4.
2. Requirements for roof hand-hole configuration have been added (Sec. 4.3.1).
3. Numerous editorial revisions have been made throughout the standard to improve clarity.
