One Water California

header-one-water

California's water professionals are responding to the State's droughts, declining water supplies and erratic weather with a new philosophy called One Water.

Drinking water, wastewater and stormwater traditionally are managed separately. Today, we view them all as one water. Across the State communities are planning to integrate infrastructure across the water cycle. We're breaking down barriers between municipal departments and asking regulators for flexibility so we can build multi-benefit water projects.

CWEA members believe all water has value and should be managed in a sustainable, inclusive and integrated way.

We call this perspective One Water. By implementing the one water philosophy we can provide enough water for a growing California for generations to come.

This page has a wealth of info on One Water in California. Read, share and contribute.
