Fast Flow Group has been Asia Pacific's foremost specialist in rainwater drainage engineering since 1993. We were the first company to successfully bring siphonic drainage technology to ASEAN countries, China and Japan — introducing a fundamentally superior approach to managing rainwater in large and complex buildings.
Over three decades, we have continuously advanced the application of siphonic technology — solving sophisticated drainage problems that conventional systems could not address, and delivering engineered solutions for some of the most iconic structures across the region.
In 2007, Fast Flow invented the world's first pressurised balcony drainage system — the psBalcony™ — a patented two-phase flow technology that prevents backflow and achieves more than twice the flow capacity at half the pipe size of conventional gravity drainage.
