WHAT WE DO
Six ways we protect
Pacific water

THE FOUNDER’S STORY
It started with a father’s worry about his children’s water.
In 2011, Aisea Langi was living in Tonga and troubled by what his children were drinking from their rainwater tank. What he found — years of sludge, debris, and contamination — became the spark for everything CHW has built since.
He invented a custom vacuum system, co-founded CRI Tonga, and began cleaning community tanks for free. The first village was Halaleva. Then 34 tanks in Houma at no charge. Then cyclone disaster response in Ha’apai. Then Fiji — where CHW and the SOF filtration system were born.
Today CHW serves governments, militaries, schools, hospitals, and communities across two Pacific nations — with expansion planned across the wider Pacific.

Village Filtration — Built from Local Materials

The manpower and equipment built and designed by OMNI Rainwater Services was able to tackle all 9 tanks in a relatively short span of time. CRI in cooperation with OMNI generously donated their time and effort to help this community.
