Easy-assemblable Stormwater Geocellular Module for Underground Installation with Eco-friendly Recycled PP Rainwater Harvesting Module

The Vantra Collection and Drainage Module is a high-performance geocellular solution for underground rainwater harvesting, detention and controlled drainage. Built from high-strength virgin polypropylene, this modular system captures stormwater runoff, stores rainwater underground and supports reliable water reuse for irrigation, road washing, toilet flushing and landscape replenishment.

• Ultra-high void ratio ≥95%: Maximizes effective water storage capacity within limited underground space, far more efficient than concrete tanks.
• Heavy-load structural design: High compressive strength, certified for installation under car parks, driveways and green areas.
• Flexible interlocking modular assembly: Snap-fit connection without welding or glue; freely adjust tank shape and volume to fit complex site conditions. Fast on-site installation, short construction cycle and lower excavation cost.
• Multi-functional dual mode: Works for rainwater harvesting and reuse, stormwater attenuation, runoff control and groundwater recharge, helping reduce urban flood risk and relieve municipal drainage pressure.
• Long service life and eco-friendly: Acid and alkali resistant, anti-aging, 100% recyclable PP material. Buried underground with no occupation of ground surface space, fully compliant with SUDS, sponge city and sustainable drainage requirements.
• Easy inspection and maintenance: Reserved channels for sediment cleaning and pipeline integration, compatible with geotextile, geomembrane, filters and overflow accessories to form a complete rainwater management system.

Wide applications: commercial complexes, residential communities, municipal roads, parks, stadiums, industrial parks and landscape projects.
