Arborflow
Greenleaf’s sustainable urban drainage system – Arborflow – has been developed as an effective and environmentally robust means of managing surface water run-off.
Ideal for use in urban areas where space is at a premium, Arborflow markedly reduces the velocity and flow rate of surface water run-off in urban areas. Designed for a given catchment area it can contribute towards meeting the discharge rates allowed and set by regulatory authorities.
Crucially, the Arborflow tree-pit system also filters out harmful pollutants using a special species of reed that collects, processes and breaks down pollutants and contaminants carried in surface water. Renowned for its many uses, 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 RainTroughs, through which surface water passes before flowing into Greenleaf’s 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.
Arborflow’s design allows the water to be discharged into surrounding sub-soil, 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, Greenleaf’s Arborflow gives water every opportunity to penetrate a tree’s deeper root zone – essential for its growth and full-maturity potential.
Sustainability and the achievement of the highest standards of environmental performance are at the forefront of Greenleaf’s activities. To combine storm water management within urban tree planting design achieves just this.
