ChallengeIn much of Southeast Asia, clean water is a daily uncertainty. Rural families often rely on rivers or ponds contaminated with bacteria and viruses, turning every sip into a gamble. Disasters make the crisis even more severe. When earthquakes or floods strike, water supply systems are usually the first to collapse, leaving communities vulnerable to outbreaks of cholera, dysentery, and other deadly diseases.  Conventional responses, like centralised treatment plants or bottled water shipments, are too slow, too costly, and too fragile to provide lasting relief. What is urgently needed is a solution that can be deployed rapidly, sustained over time, and maintained even in the harshest conditions.     SolutionWateroam was founded to close this gap with technology designed for speed, resilience, and impact. Its flagship ROAMfilter™ Technology is a portable water filtration system engineered for both rural communities and disaster zones. The device uses advanced membrane technology that removes bacteria, viruses, and other contaminants with proven effectiveness under the WHO Household Water Treatment Evaluation scheme. Compact and lightweight, it can be carried into remote areas or crisis sites and set up in minutes.  The system is built for durability, with a lifespan of more than two years, and designed so that local communities can maintain it themselves with minimal training. Beyond the technology, Wateroam partners with governments, NGOs, and humanitarian organisations to ensure fast deployment when disasters strike. Its clients include Singapore Red Cross, Mercy Relief, Relief Singapore, WHO Laos, PUB, and NUS Office of Global Health. Along the Myanmar–Thai border, more than 20,000 refugees now rely on Wateroam’s systems for daily drinking water. ImpactIn the past five years, Wateroam has delivered clean water to tens of thousands across Southeast Asia and beyond. Following the 2025 Myanmar earthquake, the most devastating in the nation’s history, the team mobilised within 24 hours. In less than two weeks, over 300 ROAMfilter™ units were deployed, securing safe water access and reducing the risk of outbreaks in communities already shattered by the disaster.  In Laos, the filters supplied hospitals in Vang Vieng throughout 2024, keeping essential healthcare services running uninterrupted. Beyond the region, units have also reached conflict zones, from Ukraine in 2023 to Gaza in 2024.  The ripple effects are wide-reaching. Families are spared the costs and setbacks of waterborne illness. Children attend school more regularly. Communities grow more resilient, no longer trapped in cycles of water poverty. Commercially, Wateroam has built steady annual revenue of around S$250,000, powered by a mix of humanitarian partnerships and private-sector adoption. This financial stability enables ongoing reinvestment in technology and growth.   Future outlookIn the near term, Wateroam aims to expand distribution networks across Southeast Asia and secure at least three new partnerships with agencies and NGOs to strengthen disaster-response capacity. Recurring cartridge sales will continue to reinforce its self-sustaining model.  By 2030, the company’s ambition is to provide 30 million people worldwide with access to safe drinking water. This will be achieved by entering ten new markets, establishing regional maintenance hubs, and scaling collaborations with humanitarian organisations.  Wateroam is showing that safe water can be delivered light, fast, and durable. Once a fragile lifeline, clean water is becoming a dependable foundation for health, dignity, and resilience.
