Root Watering System - Supplemental (RWS S) 10” Models

Rain Bird’s Root Watering System (RWSS) 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 10" (25.4 cm). The RWS S models are 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
