This year’s WEFTEC, the Water Environment Federation's Technical Exhibition and Conference, lived up to its reputation as the water sector's leading marketplace for transformative ideas and innovations.

WEF convened thousands of attendees from all over the globe, representing municipalities, engineering firms, manufacturers, environmental organizations, and academia to share knowledge, explore cutting-edge technologies, and collaborate on creating a life free of water challenges, the WEF vision.

WEFTEC 2023, the 96th edition of the event, included attractions like drones flying in a new, dedicated pavilion and a unique Opening General Session (OGS) that used music, storytellers, and photography to celebrate water, people, and community.

“In this year’s Opening General Session, we wanted to explore ideas about who’s part of the water community, how we engage with that community, and how we create and deliver solutions that effect positive change,” said Ifetayo Venner, 2022-2023 president of WEF’s Board of Trustees.
