A diverse panel of women shared their experiences and insights on the barriers women face entering the water sector. The panel discussed key topics for women entering our profession. From available jobs, social norms and biases to the lack of mentoring programs. Hear from women working on the front lines and share your ideas.

The event was jointly organized and hosted by BAYWORK and CWEA.
