GreenBlue Urban’s compact SuDS tree pit surround, StormFormTM – part of the ArborFlow family – has been developed as an effective means of managing surface water run-off through tree pits. Ideal for use in urban areas where space is at a premium, StormFormTM handles extreme rainfall events in urban areas with ease.

With super-fast flow-through rates and large storage capacity, StormFormTM is perfect for attenuating peak flows during the most extreme storm events and directing the water right into the tree pit where pollution and further capacity storage is available.

StormFormTM is an ingenious multi-functional system combining stormwater capture and storage, silt/debris capture, root control, primary irrigation and tree grille all on one easy-to-assemble, robust unit.
