Get Involved

Water doesn't recognize borders — and neither do the threats it faces. Our international teams work 24/7 to defend it.

This work is possible because of partners like you. Learn how you can join.

We believe that nature can heal if we restore what was lost. Our 20-year track record shows that grassroots action works.

The water that flows through you connects you to 7 billion people — and future generations. Protect it with us.

'Thirty years ago, this river was dying. Through their work, the ecosystem breathes again. I watch the difference daily.' — Dr. Robert L.

The science is clear: healthy water systems feed us, sustain us, and deserve our protection. We predict risks so policy can shift.
