Our Mission

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

This work is possible because of donations like you. Your voice is essential.

Our Mission

The science is clear: healthy water systems feed us, sustain us, and deserve our protection. We propose solutions so nature can recover.

• Climate adaptation for future security

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

Our Mission

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

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across political boundaries to solve problems at their source.
