Calling All Water and Wastewater Enthusiasts!
All roads lead to Chicago, Sept. 27 to Oct. 1, for #WEFTEC 2025, where the water community connects!
UPDATE: We’re heading back to New Orleans for WEFTEC 2028! While Anaheim, Calif., was originally announced a number of years ago, the ongoing success and growth of WEFTEC requires a larger venue. Thanks to our amazing WEF community for your continued dedication! We’re excited to return to NOLA’s vibrant energy and hospitality, and look forward to changing up the rotation by heading to Atlanta in 2030.

Future WEFTECs
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 also become the world’s leading water quality conference.
