Rain Bird - RWS Mini Root Watering System

Rain Bird’s Root Watering System (RWS) enables vital water, oxygen, and nutrients to bypass compacted soil and directly reach tree and shrub root systems.

Its patented basket weave canister allows ground installation to a depth of 36" (91,4 cm) for the RWS, 18" (45,7 cm) for the RWS-M and 10" (25,4 cm) for the RWS-S. The RWS is intended for use with water dispensing devices such as a bubbler head or a drip emitter.

The RWS promotes tree and shrub investment protection, watering efficiency and landscape aesthetics through deep root growth and tree development.

Tree & Shrub Investment Protection

In a typical transplant project, as many as 20% of trees do not survive beyond two years. Over 50% of newly planted tree mortality is due to water and nutrient stress. Rain Bird’s RWS provides subsurface irrigation and aeration designed to prevent tree and shrub transplant shock. It allows the roots to grow deeper and broader resulting in greater tree stability, higher survival rates and long-term healthier growth.

Watering Efficiency

Subsurface, deep root watering and aeration ensures tree health and promotes accelerated growth. Subsurface watering is intelligent irrigation. RWS minimizes the total water volume required to irrigate trees, reducing water loss due to evaporation, wind and edge control losses.

Landscape Aesthetics

The RWS helps prevent shallow root growth by minimizing water run-off and damage to hardscapes. The aesthetically designed subsurface bubbler is contained with the RWS tube. The below-grade installation contributes to a safer and more reliable installation -no one is tripping over or breaking above-ground irrigation hardware. The below-grade installation promotes a landscape’s natural appearance.

The variety of models accommodates design flexibility. It is simple to specify, requiring a single model number instead of a host of parts.
