StormForm - Root Management System with Grille

GreenBlue Urban’s compact SuDS tree pit surround, StormForm - 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, StormForm handles extreme rainfall events in urban areas with ease. 

With super-fast flow through rates and large storage capacity, StormForm 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.
