SCWC’s membership, approximately 200 organizations strong and growing daily, spans across Southern California, from Kern and Ventura down to San Diego and Imperial counties.

We recognize the rich diversity of Southern California’s people and cultures and see clearly how we are all connected by the need for a safe, affordable and reliable water supply. We believe that working with and learning from a broad range of people helps us address California water issues more creatively.

Our members represent water interests and stakeholders from a multitude of interest areas – public and private – allowing SCWC to fully engage on California’s most critical water issues. This diversity allows SCWC to create a comprehensive and authoritative dialogue to build a safe, reliable water future for California.
