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

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
