RWS Root Watering System

Rain Bird’s RWS Root Watering System is designed to deliver water, oxygen and nutrients to tree root balls and their surrounding soil, encouraging deeper root growth and reducing transplant shock.

  • Patented basket weave canisters installed at grade, enabling below-ground irrigation and reducing water lost to evaporation and runoff
  • 18- and 36-inch models feature a top assembly with integrated clips for tool-free grate installation
  • Recessed stem allows for use of Rain Bird’s EMT-6XERI six-outlet drip manifold device, making it possible to irrigate the host RWS unit, other RWS units, or even provide surface irrigation to other trees or plants nearby for better design flexibility
