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?

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?

Allow for expansion and contraction of drip tubing

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
