Leadership. Passion. Collaboration. Scholarship. Service. These are the core values that guide the Water Environment Federation (WEF) and its members in fulfilling our mission of protecting public health and the environment.

The Water Environment Federation (WEF) is a not-for-profit technical and educational organization of 35,000 individual members and 75 affiliated Member Associations representing water quality professionals around the world. Since 1928, WEF and its members have protected public health and the environment. As a global water sector leader, our mission is to connect water professionals; enrich the expertise of water professionals; increase the awareness of the impact and value of water; and provide a platform for water sector innovation.

Previously called the Federation of Sewage Works Associations (1928), the Federation of Sewage and Industrial Wastes Associations (1950), and the Water Pollution Control Federation (1960); the name was changed to the Water Environment Federation in 1991 to reflect an expanded focus of non-point and point sources of pollution. 

WEF and its global network of members and Member Associations (MAs) provide water quality professionals around the world with the latest in water quality education, training, and business opportunities. WEF’s diverse membership includes scientists, engineers, regulators, academics, utility managers, plant operators, and other professionals. WEF uses this collective knowledge to further a shared goal of improving water quality around the world.
