Opening General Session
Monday, October 2 at 8:30 a.m. CT

Creating a life free of water challenges for all requires us to expand our ideas around who is part of the water community, how we connect with and engage in our communities, how we create and deliver solutions, and to reimagine what we leave behind. This year’s Opening General Session (OGS) will combine culture, music, and storytelling to celebrate water, people, and community, and will inspire us to think differently about our work and our world.


Learn from the brightest, most innovative minds and strengthen your skillset through WEFTEC's world-class education. WEFTEC delivers everything you need about water quality through many different learning styles.
