Drip Irrigation Overview Trends / Drivers for Growth Types Differences vs. Conventional Irrigation Benefits
Drip Irrigation Trends / Drivers Record drought Water restrictions, increased
regulation Drip is often exempt from
restrictions The need for efficiency is
driving the growth in drip irrigation
Types of Drip Irrigation Point-Source
Common in sparse planting configurations
Allow you to put water near the plant’s root zone
Dripline Ideal for densely
planted or narrow areas
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
Keys to a Well Designed Drip System
Pressure Regulation – Drip zones operate at lower pressures than traditional spray zones
Filtration– Necessary to keep emitters clear of dirt and debris
Benefits of Drip Irrigation Highly customizable
Healthier landscapes– Puts water closer to the root zone
Eliminates run-off , overspray and expensive damage to hardscapes
– Staining – concrete, pavers and walls
– Rotting of wood fences, decks and planters
Shorter irrigation run times– Lower irrigation water bills
Makes the customer a better steward of the environment

Drip Irrigation
Benefits of Drip Irrigation
Match the water application rate to each plant.
Match the application rate to the soil’s infiltration rate.
Apply water directly to the root zone to reduce overspray and evaporation.
Properly designed and installed dripline systems can be over 90% efficient.
Why use Drip Irrigation?
Asphalt Damage Water Spots on Vehicles
Blockage from Foliage
Liability to Pedestrians & Vehicles
Stained Fences, Walls and Windows

Suitable for both on-surface and sub-surface applications. Indicator is installed on the exhaust header. If the indicator does not pop-up and seat – you should look for the
following: Did the valve not open? Does the filter need to be cleaned? Is there a break in the dripline? Did the main valve open?

0.1 inch per 100’ for every 1 degree F of temperature change
Example: 260’ tubing length and 40 degrees temp change
2.6 (100’ length) x 0.1 (in/100’) x 40 (degrees F) = 10.4”
Flushing the system
Flush the system every two weeks for the first 6 weeks and check the water that is flushed out for cleanliness.
Establish a regular flushing schedule for the future after the initial checks.
Flush the system well after any repairs are made.
Flushing the system
All irrigation systems require maintenance
Spray systems tend to be more forgiving than drip
Maintenance should be regular and consistent
Drip maintenance might be harder to detect problems
