About WEF

The Water Environment Federation (WEF) and its members work every day to fulfill our Mission of inspiring the water community in pursuit of human and environmental well-being.

The Water Environment Federation (WEF) is a not-for-profit technical and educational organization of more than 30,000 individual members and 75 affiliated Member Associations (MAs) representing water quality professionals around the world. Since 1928, WEF and its members have protected public health and the environment. WEF and its global network of members and member associations 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.

WEF is operating under a new Strategic Plan built on the vision of a life free of water challenges. Our ultimate goal is a world where each person has access to clean water and sanitation, where communities prosper, and where nature thrives. The key strategic goals under the new Strategic Plan are: 1) to attract and develop a diverse and passionate workforce; 2) to cultivate a purpose-driven community to sustainably solve water challenges for all; and 3) to lead the transformation to the circular water economy.

The new Strategic Plan embodies WEF’s embrace of diversity, equity, and inclusion in all that we do. WEF is committed to equity and inclusion in all aspects of our work, including within the governance structure and leadership, WEF partners, WEF staff, and the WEF membership. This commitment to diversity, equity and inclusion will guide our work and our programs, culminating in outcomes that improve public health for all.

EF is a not-for-profit technical and educational organization of more than 30,000 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.
