Siphonic Rainwater
A high-performance rainwater drainage system for large-roof buildings, designed to handle heavy rainfall with smaller-diameter piping, reduce installation space requirements, and support rainwater harvesting for reuse as part of sustainable building practices.
• Specialized roof outlets prevent air from entering the piping, enabling full-bore (full-pipe) flow.
• Horizontal pipes can be installed without a slope, minimizing conflicts with structural elements and other MEP services.
• Fewer vertical downpipes and smaller pipe diameters reduce space requirements and lower installation costs, making the system ideal for medium- to large-roof buildings.
• Well suited for factories, warehouses, shopping malls, and other medium- to large-scale buildings.
