Drivers of the Landscape Drip Market

1) Growing understanding and acceptance of how to use drip irrigation in commercial and residential applications

2) Water Shortages/Restrictions/IncentivesResearchers say that at least 36 U.S. states will face water

shortages in the next five years because of rising temperatures,drought and population growth.

3) Cost of Water

Why use Drip Irrigation?

Helps conserve water and energy

Helps prevent:- Overspray onto sidewalks, buildings & roadways- Plant wetting- Irrigation of non-planted areas- Wind Drift

Can reduce initial irrigation equipment costs

Reduces liability

Can increase the size and quality of plants

Most efficient way to irrigate small spaces

Why use Drip Irrigation?

Asphalt Damage Water Spots on Vehicles

Blockage from Foliage Liability to Pedestrians & Vehicles

Emitter on Sch 80 riserXBD-80

Differences vs. Conventional Irrigation

Device flow rates are measured in GPH vs. GPM– Low flow rate equates to reduced erosion and runoff– Low flow rate means more emission devices per valve

Operating pressure window is typically 15-50 psi

Water is typically filtered to 120-200 mesh

Both PVC and/or polyethylene drip tubing may be used

Large Planting Beds / Sparse Planting

Large Planting Beds – Sparse Planting

The Challenge:The Challenge:

Sparse Planting

Concern about overspray

− Wind drift into homes/yards

− Weed growth between plants

− Wasted water

•• Spray heads / RotorsSpray heads / Rotors

•• DripDrip

The Solution:The Solution:Multi-Outlet Xeri-Bug

− Provides six outlet ports

− Precise water placement at the base of each plant

No excess water to feed unwanted weeds

Fulfills the watering needs of drought tolerant plants

Very important to bury the ¼”distribution tubing

Pattern never gets out of adjustment


Keys to Success in Landscape Drip

Select the proper drip products for your application

Use pressure regulation

Filter water to prevent clogging

Put flush valves at the end of each lateral

Flush the system periodically
