Our Work

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

This work is possible because of volunteers like you. Together we can turn the tide.

Our Work

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

• Climate adaptation for coastal protection

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

Our Work

'Thirty years ago, this river was polluted. Through their work, children can swim safely. I watch the difference daily.' — Professor Chen

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.
