For ports and airports, where efficient water management is critical due to large surface areas to drain with heavy traffic loads, a versatile hybrid linear slot drainage system is emerging as a viable alternative on the market.

This water management system is suitable for a broad spectrum of applications from industrial to public realm, car parks to airports and ports, and offers unique advantages and technical superiority over current offerings, such as:

  • Superior structural integrity: Its twinwall conduit has a greater wall thickness (28mm minimum for the 150mm size) compared to other systems where wall thickness is minimal. This also eliminates the requirement for any further structural surround, ensuring long-term strength, stability and performance.
  • Corrosion resistance: Unlike alternative systems, the plastic conduit will not rust, providing a longer lifespan and reducing maintenance costs.
  • Quick and cost-effective installation: The lightweight design and interlocking sections allow for faster installation with reduced labour costs, minimising disruption to operations.
  • Enhanced load capacity: With options for D400 and F900 loading, the system can handle the heavy loads typical in port and airport environments.
  • Pedestrian safety: The system features a pedestrian-friendly top with 2 x 10mm offset slots for better surface-level interception, a unique feature to our system.
  • Environmental sustainability: Made from 100% recycled HDPE, ensuring that no new plastic is produced for its manufacture. This system is fully recyclable at end of life, contributing to environmental sustainability and meeting stringent environmental regulations.

Called the Swarm Aqua® range and owned by EJ, it is designed to meet the demands of both small residential sites and large industrial plots. It offers real choice to design engineers who need to manage large volumes of surface water and cater for significant vehicular loads. 

Other attributes include:

  • Variety of sizes and materials: Available in lengths of 2 meters and widths ranging from 150mm to 600mm, with cast ductile iron offset tops for added strength.
  • Durability: The strong HDPE Twinwall body is made from 100% recycled material, offering a design life of over 60 years and resistance to most chemicals.
  • Installation efficiency: Shallow throat height reduces excavation and concrete requirements, while lightweight units and interlocking sections ensure quick and easy installation.
  • Performance: Features such as twin offset 10mm openings for improved interception, a smooth bore for efficient water flow, and a steel throat section for added durability.
