Standards

ANSI-Accredited Standards of Minimum Requirements

The American Water Works Association first published consensus documents in 1908. Today there are more than 180 AWWA Standards. From source to storage, from treatment to distribution, AWWA standards cover all areas of water treatment and supply.
 
These documents reflect the state of the industry. As new technologies emerge, new Standards develop. 
 
These AWWA standards address all facets of water treatment and delivery.
