RootRain Precinct and ArborVent

RootRain Precinct

The RootRain™ Precinct and ArborVent™ kits are for central urban locations requiring a permanent irrigation/aeration solution and heavy duty cast-iron inlet.  The Precinct inlet has a round-shaped top, and the ArborVent inlet has a square-shaped top.

The RootRain Precinct and ArborVent series have been specially designed to interlock with our range of integrated tree grilles. This provides a tamper resistant system that will also prevent the inlet sinking as a result of any soil settlement around the tree.

  • Lid lifts and swings to one side for fast irrigation
