Island-built water solutions for schools, villages, health centres and institutions across the Pacific — using technology designed here, for here.
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.

Whether you're a school, a village, a government body, or a funder — CHW responds to every enquiry personally. Emergency situations are prioritized.
