Standards
AWWA Standards are consensus documents created by volunteer committees and accredited by ANSI. They offer minimum requirement guidelines on all facets of water. As technologies evolve, AWWA Standards are a trusted resource that reflect the state of the industry.
ANSI-Accredited Standards of Minimum Requirements
AWWA 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.

Explore The Latest Standards
As water technologies grow and emerge, AWWA Standards are continuously updated or released to address them. Reference the latest standard editions to ensure you are working off of the most up-to-date information. Formed in 1920 and now nearly 1,600 volunteer subject matter experts strong, the AWWA Standards Council guides standard updates.

Credibility & Longevity
Since the first AWWA committee on product standardization was formed in 1881, we have been on the forefront of product and operations standards for the water community. From our first official standard released in 1908 to the formation of the AWWA Standards Council in 1920, to the 190+ standards we have produced to-date, we have been a constant expert resource.

Standards Notices
AWWA Standards go through a broad-based public review and comment on draft standards. A group or consensus body that includes representatives from materially affected and interested parties participate in this consensus process. This ensures AWWA Standards represent a true industry-wide consensus that can be trusted and widely accepted.
