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.





In 2020 the AWWA Standards Council celebrates 100 years of dedicated service to public health.

From the initial standards covering pipes, water meters and steel water storage tanks, AWWA volunteers have guided the expansion of the standards program. The Council has grown from five to 24 members, with nearly 1,600 volunteer subject matter experts serving on 72 Committees. There are 189 current AWWA Standards, and Standards Committees have produced 16 of AWWA's Manuals of Practice.
