Healthy urban trees and effective stormwater management go hand in hand. Integrated tree pit systems capture, filter, store, and reuse rainwater to support healthy tree growth while creating more resilient urban infrastructure.
Integrated tree pit systems combine the essential components for healthy urban trees and effective stormwater management into one coordinated below-ground solution. By capturing, filtering, storing, and reusing rainwater within the tree pit, they provide the water trees need while reducing runoff and improving water quality.
Systems such as ArborFlow integrate tree planting infrastructure with sustainable drainage within a coordinated system.
Controlled inflow of surface water into the tree pit
Storage of stormwater within engineered soil volumes
Integration with structural soil cell systems where required
Compatibility with standard pavement construction methods
Flexibility to adapt to site conditions and drainage strategies
Successful LID tree pit systems combine several infrastructure components working together. These elements allow stormwater to enter, move through and be managed within the system, while also supporting healthy tree growth and maintaining pavement performance.
Typical components may include structural soil cell systems, drainage and distribution components, irrigation and aeration infrastructure, root management and protection systems, and surface finishes such as tree grates and guards.
Soil cell systems designed to protect uncompacted soil beneath hard surfaces
Attenuation modules designed to store and distribute water within ArborFlow systems
Integrated stormwater management system that captures, filters, stores, and reuses rainwater to support healthy urban trees
Tree irrigation and aeration systems that deliver water directly to the root zone
Systems that support healthy root conditions through irrigation and oxygen exchange
Geotextiles and membranes supporting soil separation, filtration and ground stability
