RAIN
FOR
CHANGE.

Every Drop Restores. Every Act Matters.

Hello, we are the

International Rainwater harvesting Alliance

(just call us IRHA)

Since 2002, IRHA has been developing sustainable rainwater harvesting and management solutions to support the communities most vulnerable to climate change.

If you believe in empowerment, balance, and rain-powered change

Welcome !

We catch rain.
We create change.

Where others see water scarcity, we see untapped potential.
We work where climate extremes hit hardest — catching rain where it falls and transforming rooftops, hillsides, and dry fields into reservoirs of hope and resilience.

Through nature-based solutions and community-based water and land management, we restore degraded soils and protect landscapes.

We stand alongside children, women and men turning each drop into dignity, balance, safe water access, and food sovereignty.
