Rain Bird Root Watering System, RWS, RWS-M, RWS-S Installation Instructions Manual

How to select and install a
Root Watering System

The Rain Bird Root Watering System (RWS) consists of a perforated polyethylene cylinder
with 14,000 openings to eectively deliver water, air and nutrients to the root system of
trees and shrubs. It easily connects to irrigation lateral lines or can be installed in drip zones.
It is available in 3 sizes: 36", 18" and 10".

Benets include:

• Optimal growth rates – Deeper root growth and root mass means a healthier,
faster growing tree

• Investment protection – Healthier roots help trees survive transplanting
and provide stability in high winds

• Watering eciency – Subsurface irrigation minimizes run-o and evaporation

• Landscape aesthetics – Installs at grade and helps minimize damage to hardscapes

Easy to install in just 3 simple steps:

1

Choose correct RWS units

2

Determine number of units per tree/shrub

3

Space appropriately

Dig hole and insert
tree/shrub before
installing RWS to avoid
damage to units.

Keep RWS top even with
ground surface.

Keep RWS on its own
irrigation zone.
