Understanding Drip Irrigation Systems

Components of a Drip Irrigation System

Emitters

Drip irrigation systems rely heavily on drip emitters to deliver water directly to plants with precision. These emitters, part of the larger drip system, are connected through drip tubing or drip line, and work in conjunction with other components such as the drip irrigation faucet, pressure regulator, and filters.

By adjusting the flow rate of the emitters, you can ensure an efficient and uniform water supply to garden beds, raised beds, and various plants. Proper installation and maintenance of these emitters, including connecting them to the poly tubing and using fittings like hose threads and pipe threads, are crucial for optimizing the overall performance of your irrigation system.

Tubing and Connectors

In a drip irrigation system, tubing and connectors are crucial for distributing water efficiently to plants. Poly tubing and drip line are used to transport water from the drip irrigation faucet to various parts of the garden, connecting with drip emitters and micro tubing through simple connection methods like hose threads and pipe threads.

The system also includes essential components such as pressure regulators, filters, and fittings to ensure a consistent flow and prevent clogs. Proper installation and maintenance of these parts, including using teflon tape and checking for high pressure or leaks, are vital for a well-functioning irrigation system that effectively waters garden beds, raised beds, and other plant areas.

Filters and Pressure Regulators

Filters and pressure regulators are essential components of a drip irrigation system, ensuring the efficient operation and longevity of the system. Filters prevent debris from clogging drip emitters and micro tubing, while pressure regulators maintain a consistent and appropriate water pressure to avoid damage to the system.

Proper installation and maintenance of these parts, along with other components like the drip irrigation faucet and poly tubing, are crucial for a well-functioning and effective irrigation system.

Types of Drip Irrigation Systems

Surface Drip Irrigation

Surface drip irrigation is a type of drip irrigation system where water is delivered directly to the soil surface through drip emitters placed along a drip line or drip tubing.

This method efficiently targets garden beds and raised beds by distributing water near the plant roots, minimizing evaporation and runoff. Essential components like the drip irrigation faucet, pressure regulators, and filters are crucial for ensuring optimal flow and maintaining system efficiency.

Subsurface Drip Irrigation

Subsurface drip irrigation involves placing drip emitters below the soil surface, allowing water to be delivered directly to the root zone of plants. This type of drip irrigation system minimizes evaporation and runoff, making it highly efficient for garden beds, trees, and shrubs.

Key components like the drip irrigation faucet, pressure regulators, and filters are essential for maintaining proper flow and ensuring effective irrigation.

Drawing up Your Irrigation System

To begin with get out your pen, pad and tape measure for the planning session. Your drip irrigation system begins at the water source, whether that's a free-standing faucet near your garden, a hose bib on your house, a spigot near a well ditch or other water source.

• Start by measuring how far it is from your water source to your gardens.
• Decide whether you can water all your gardens with one line from the source or if you'll need several lines such as if your gardens are located in different directions from the faucet, or you need to determine if you need more feet of line than the system can support at once.
• You'll also need to measure your garden beds, length and width.
• From your measurement you can now draw out all of your gardens on paper.
• Note each measurement on your drawing then draw in or note what you'll be watering–veggie beds, flowers, perennials, trees and shrubs should all be included in your diagram.

Now it's time to take the time and analyze what kind of drip system is going to be the best for you–drip tape, emitterline, soaker hose, sprayers or drip emitters. You need to incorporate several types for the most efficient irrigation. Check out the corresponding videos on each type of irrigation system to learn more about what each system is used for before you decide, or you can check out any one of our Drip Irrigation Set-up Diagrams at groworganic.com.

Water Hook-Up

The first part of your system from your water source to the edge of your garden will be the same no matter what kind of drip irrigation system you choose.

• At the end of either a hose or faucet the first thing you'll install is a Y-Connector or a you can use a 4-Way Connection. This allows you to water other things without disconnecting your drip system.
• Next install a Vacuum Breaker. This will prevent back flow from your irrigation system and prevent your water source from becoming contaminated. This will be especially important if you plan to be using a fertilizer injector system.
• If using a fertilizer injector system now is the time to install it, however, if you are using a timer, you should install the injector after the timer.
• A filter should be installed next, this will prevent your drip system from getting clogged. A Flushable Y-Filter is very easy to clean or you can use an economical In-line Filter. A filter is especially important if you're using a fertilizer injector or if your water source is from a well, irrigation pond or a ditch.
• Next is a timer (optional). There are a variety of timers to choose from. Anywhere from a simple mechanical timer to a fully digital timer. Adding a timer will save you time and money on your water bills.
• Most drip systems work best with a fixed pressure regulator. The type of pressure regulator to use will be based on the type of drip system you're going to be installing. If you are using multiple types of drip irrigation, install the type of pressure regulator needed before the line (ie. install a 10 psi pressure regulator before drip tape line).

Getting Water to the Garden–Adding the Supply Line

Last step is to add the 1/2" poly tubing, which will bring the water to the edge of your garden. So at the end of the pressure regulator you'll need to install a Power-Loc - 3/4" Female Hose Starter Fitting Attach your 1/2 inch poly to the starter and then power lock it in place.

• Where the poly hits the ground, to avoid kinking of hose, attach either a Power-Loc Elbow, or if you want to split the line into two, add a Power-Loc Tee.
• You can stake it down with Ground Staples or you can hold it firmly in place along a wooden deck or raised beds with Mounting Clips.

Your irrigation is ready for the next step, how to get the water from the poly tubing to the plants. Check out our corresponding videos on how to set up a drip irrigation using emitterline, soaker hose, drip tape and all the rest of the accessories, and grow organic for life!
