WEFTEC History

Since its formation in 1928, WEF has been holding annual meetings to provide a forum for knowledge and technology exchange within the water and wastewater fields. Since then, WEFTEC has not only grown in the size of exhibits and technical sessions, but has become one of the world’s leading water quality conferences. 

In 1941, the then-known Annual Conference featured 5 sessions, 13 technical papers and an attendance of 556. By the 1970s, attendance had grown to 8,716 and featured 37 sessions with 146 technical papers. Growing steadily throughout the past four decades, the conference continues to set new technical program and exhibition records each year. 

Renamed WEFTEC in 1994 to increase both domestic and international recognition, WEF’s annual exhibition has been ranked in the top 1% of all trade shows in North America for the past five years and counting! 

With all that WEFTEC has to offer it is the clear choice for anyone interested in learning and sharing more about the latest in water quality developments, research, regulations, solutions and cutting-edge technologies. Don’t miss your opportunity to be a part of the WEFTEC Experience today!
