SUDRAIN CO., LTD. (SUDrain) is a social enterprise that provides low-cost, eco-friendly wastewater treatment solutions using recycled coconut fibre. We support eco-resorts, livestock farms, public spaces, and vulnerable communities with sustainable wastewater treatment systems that are easy to maintain and highly effective in removing pollutants. Our vision is to extend the life cycle of water by improving living conditions through environmentally friendly solutions that contribute to the circular economy, creating a future where clean water is accessible and communities thrive in harmony with nature.
SUDrain’s services include consultation and customised design of decentralised, nature-based wastewater treatment systems. We also offer full installation and construction services, including toilet facilities equipped with septic tanks designed specifically to integrate our coconut fibre filtration system. We provide coconut filter replacement services every 3–5 years to ensure long-term efficiency, and we conduct wastewater quality assessments to monitor environmental impact and system performance. Beyond technical services, SUDrain engages with communities through behaviour change communication and training, empowering local stakeholders to manage their systems sustainably.
