Wavin Certaro Lamella HDS

Urban areas face increasing challenges from polluted stormwater runoff. The Wavin Certaro Lamella HDS offers a compact, high-performance solution for sediment separation, helping cities protect their most valuable resource: clean water. Designed for limited spaces and large catchment areas, this system ensures efficient treatment of surface water while minimizing installation and maintenance efforts.

    Engineered for Performance with hydrodynamic–lamella efficiency

    Tackling Urban Water Pollution at the Source

    Stormwater runoff from roads, rooftops, and industrial areas carries a complex mix of pollutants—heavy metals, hydrocarbons, microplastics, and nutrients. These contaminants, often bound to fine sediments, pose a serious threat to water quality and aquatic ecosystems.

    The Wavin Certaro Lamella HDS is engineered to intercept these pollutants before they enter natural water bodies. By combining hydrodynamic separation with lamella settling technology, it delivers high removal efficiency in a small footprint—ideal for dense urban environments.

    Compact Design, Maximum Performance

    Despite its compact Tegra DN1000 chamber, the Certaro Lamella HDS handles runoff from areas of 2,000 m²—and even larger catchment areas when configured with multiple units or adapted flow rates.

    It delivers for an area of 2,000 m²:

    • 80% total sediment removal efficiency
    • 62% removal of fine particles (<63 µm)
    • 98% removal of coarse particles (63–400 µm)

    Its modular design allows for flexible configurations, including optional risers for deeper installations and bypass options for high-flow events.
