ArborFlow is a sustainable urban drainage system that has been developed as an effective and environmentally robust means of managing surface water run-off.

ArborFlow markedly reduces the velocity and flow rate of surface water run-off in urban areas where space is at a premium. Designed for a given catchment area, it can contribute towards meeting the discharge rates allowed and set by regulatory authorities.

Reedbed filtration

Also filters out harmful pollutants using a special species of reed that collects, processes and breaks down pollutants and contaminants carried in surface water.

Phragmites auralis, the common reed, is a perennial grass usually found in wetlands, or growing as reed beds in damp ground or standing water. Grown as part of nutrient solutions, reed beds have the ability to remove pollutants from water or treat contaminated water. The reeds have been incorporated into Rain Troughs, through which surface water passes before flowing into GreenBlue Infrastructure Solutions special soil mixture (within the StrataCell rooting profile). The system prevents small-to-medium sized particles in the water from passing through, or clogging up the troughs.

Water flow

ArborFlow’s design allows water to be discharged into surrounding subsoil, to be absorbed by the trees’ root systems, or to find its way into the specially designed flow-control chamber positioned on the outfall of the tree pit.

The soil used within the StrataCell rooting profile has been specially designed to withstand frequent short-term water logging without any change in its physical structure or chemical properties.

As water is biochemically vital for the growth of a tree, GreenBlue Infrastructure Solutions ArborFlow gives water every opportunity to penetrate a tree’s deeper root zone – essential for its growth and full-maturity potential. 

Benefits

  • Ideal for use in urban environments where space is a problem
  • Prevents flooding as it absorbs and contains water in the tree pit system
  • Reduces the flow rate of water run-off so that the system meets authorities’ allowable discharge rates
  • Filters out harmful pollutants and contaminants through special reed plants
  • 100% post-consumer materials have minimal or zero impact on the environment
  • Surface water is discharged into surrounding subsoil, absorbed by roots, or flows into the tree pit’s control chamber
  • Drainage channels trap silt and other organic matter, such as leaves
  • Manages water run-off at source, or as close as possible to the point where water falls
  • Increases chances of newly-planted trees reaching their full potential
  • Design and implementation meet new planning guidelines and regulations

ArborFlow can be combined with the ArborCharge combines electric car charging unit & ArborSystem to create a multi-functioning tree pit system.
