One Water California

A new era is beginning in California's water community. Drinking water, wastewater and stormwater traditionally were viewed and managed separately. Today we view them all as one water.

Across the State communities are looking to the future, they are planning projects in a way that integrates infrastructure across the water cycle in an interconnected way. This ensures our communities will have safe drinking water supplies for generations to come.

We believe all water has value and should be managed in a sustainable, inclusive and integrated way. We call this perspective One Water. And while our focus is water, our goals are tocreate thriving communities, strong economies and healthy ecosystems.
