Our Story
About Rain For All
The Philosophy of Rain
Rain is often seen as a disaster to be avoided.
But rain is also one of the greatest blessings of nature.
Heaven
Rain falls from the sky as nature's blessing, providing clean water to all.
Earth
Rain lands on Earth, nourishing ecosystems and communities sustainably.
Humanity
People work together to harvest and share rainwater for a sustainable future.
Rain For All was founded on a simple idea:
Rain should not be rejected — it should be welcomed and wisely used.
Our Logo
Our logo represents the harmony between Heaven, Earth, and Humanity.
Rain falls from the sky (Heaven),
lands on the Earth,
and is managed by people to create a sustainable future.
The design includes symbolic elements:
- •The circular shape represents the Earth
- •The central line forms the character 人 (human)
- •The raindrops represent the five oceans and six continents, symbolizing global cooperation
- •The colors are inspired by the harmony of nature
The logo reminds us that rainwater is not only a natural resource but a shared responsibility for the future of humanity.
Rain For All seeks to lead a global movement where communities around the world use rainwater wisely for safe drinking water and a sustainable planet.
Rain For All Manifesto
Rain for Drinking. Water for All.
1
Rain is a blessing from the sky.
Rain For All recognizes rain not as a threat, but as a gift from nature — a source of safe drinking water that falls freely across the planet.
2
Safe drinking water is a universal human right.
Rainwater offers a simple, decentralized, and resilient solution that can help achieve Sustainable Development Goal 6.1 — safe drinking water for all.
3
Rainwater is the most democratic water source.
Unlike rivers, dams, or deep groundwater systems, rain falls everywhere. It does not belong to any government, corporation, or institution. Rain belongs to everyone.
4
Communities are the key to water resilience.
Rain For All supports community-based rainwater systems that empower people to secure their own drinking water.
5
Knowledge and education create sustainable change.
Through programs such as Rain Schools, students and communities learn to monitor rainfall, water quality, and climate conditions.
6
Global cooperation is essential.
Rain For All works with partners, researchers, governments, and communities worldwide to expand rainwater solutions.
7
A new water culture is needed.
Humanity must move from a culture of controlling water toward a culture of living with water. Rainwater reminds us that nature already provides the resources we need.
