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



Anatomy of a Landscape Drip System

Emitter on Sch 80 riser XBD-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

Benefit Summary:Benefit Summary:

Ease of installation

No overspray

No wind drift

No exposed product

More efficient use of water

Reduced liability

Street Medians – Dense Planting



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

All plants may not have the same

daily water requirements

What would you use?What would you use?

•• 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 plantsVery important to bury the ¼”

distribution tubing




Bill of Material:Bill of Material:

•Control Zone Kit

•Multi-outlet Xeri-Bug with ½” FPT

• ¼” distribution tubing*

• ¼” tubing stakes & Bug Caps

• PVC laterals and fittings

* Note, do not run ¼” tubing more

than 5’ – 8’ from multi-outlet emitter





Precise water placement at plantroot zone

No wind drift

Less weed growth since non-

planted areas are being irrigated

Reduced water use due to higher

system efficiency




Slopes / Dense Planting



Slopes – Dense Planting


Sloped planting bed

Potential for soil erosion

Wind Drift

No curb to control water run off

Foliage blocks spray

Overspray onto hard surfaces

− Water waste

− Increased liability What would you use?What would you use?


•• DripDrip








Ease of installation

No overspray

No wind drift

No exposed product

More efficient use of water

Reduced liability

Reduced water run-off prevents

soil erosion

Slopes – Dense Planting



Parking Lots



Parking Lots – Dense Planting

What would you use?What would you use?


•• DripDrip


Concern about overspray

− Wasted water

− Increased liability

− Wind Drift

Potential for vandalism

Dense ground cover

− Foliage blocks spray

Trees included in design





Bill of Materials:Bil l of Materials:

Control Zone Kit

XPCN nozzle on 1806

Plus other related PVC

items





Exceptional uniform pattern for high

efficiency

Can still see it operating

Low flow rate = more sprays per

valve

Low trajectory, better than traditionalspray nozzle

Square pattern

Pressure compensating

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
