AWWA and their Standards |
The American Water Works Association first published consensus documents in 1908. By June 2025, there are more than 190 AWWA standards. From source to storage, treatment to distribution, the AWWA standards cover all areas of water treatment and supply.
This article contains only standards for steel products for the most common components, such as pipes, flanges, and fittings. The highlighted items in the lists below provide a limited overview of some of the standards.
