FLOLINE

Underground On-site Detention System

Product Brochure

The FLOLINE Stormwater On-Site Detention (OSD) System manages stormwater flow by temporarily storing excess surface run-off within a development before discharging it at a controlled rate into public drains or waterways, reducing flood risk.

The system comprises a buried network of interconnected FLOLINE pipes (FLOLINE 3W or FLOLINE FLEXISS), forming an underground storage tank with a controlled outlet. It can be integrated with Gross Pollutant Traps (GPTs), filters, and maintenance features, and is suitable for installation beneath green spaces or trafficable areas including carparks. WEIDA offers solutions to design, size, supply, and install OSD systems in compliance with Manual Saliran Mesra Alam (MSMA) requirements.
