The American Water Works Association first published consensus documents in 1908. Today, there are more than 190 AWWA Standards. From source to storage, from treatment to distribution, AWWA Standards cover the products and processes related to all areas of water treatment and supply.

These documents reflect the state of the industry. As new technologies emerge, new standards are developed. These AWWA Standards address all facets of water treatment and delivery.

In 2020, the AWWA Standards Council Celebrated 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 currently more than 190 AWWA Standards, and standards committees have produced more than 60 AWWA Manuals of Water Supply Practices.
