Who We Are

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 volunteers like you. Every contribution matters.

Who We Are

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

• Early warning systems of water quality shifts

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