Advantages of Drip Irrigation
- Reduces water waste
- Improves soil quality
- Improves plant health
- Reduces runoff and fertilizer use
- Reduces labor costs by eliminating hand watering and surface irrigation equipment maintenance
- Increases crop yields
Types of Drip Systems
The basic types of drip irrigation systems are:
- Gravity systems: Water from an aboveground tank, such as a cistern or pond, is gravity-fed to the plants by flexible plastic hoses, which carry water from the tank to an underground water source and back up again. This type of system requires no electricity or power source other than gravity. However, its use on large landscapes is limited by the time it takes for water to reach all areas of a large lawn or garden bed.
- Pressure systems: These employ pumps that send pressurized water through plastic tubing (which comes in many different diameters) to emitters located at intervals along your garden beds and lawns so that they can be watered efficiently without having excess runoff onto paths or driveways. Pressure systems vary widely in their design. You may want something simple like a hand pump or battery-operated system. Those with higher budgets may want something more complex, like electric pumps powered via timers; some even prefer solar energy sources.

Apply the Right Amount of Water to Plants Across the Yard
- You will need to use a timer to apply the right amount of water to plants across your lawn or fields. This is for watering at set times, so you don’t have to remember when it’s time for another watering.
- You can also use a moisture sensor that measures how much moisture is in the soil. It will tell you how much water is required based on what type of plant and how hot or cold it is outside. This way, there are no surprises about whether or not your plants are getting enough water on any given day!
- Another option is a flow meter attached directly to your drip irrigation system. This device looks like an electrical box with several small buttons attached; these buttons allow users to control how many gallons per minute (GPM) they want their system running at any given time.
Drip Irrigation System Design
Drip irrigation system design is important to the success of your drip irrigation project. The main considerations for designing a drip irrigation system are soil type and slope of the land, size of the area to be irrigated, and available water source.
The below guidelines will help you make sure your drip system is properly designed:
- Drip systems should not be installed where there will be excessive water pressure due to high clay content in the soil or because it’s too sandy. This can cause clogging or failure in some cases. If clay soils are present, consider installing multiple emitters per line (more than one emitter per line).
- It’s also best to install a filter at each distribution point on lines coming out of valves near emitters and valves near distribution points. Hence, solids will not be carried along into them by pressure generated by moving water through pipes made up entirely of PVC plastic materials without any filters inside them; otherwise, they may get damaged, causing leaks that could lead to clogs.
- If your lines are made entirely of PVC plastic materials without any filters inside them; otherwise they may get damaged, causing leaks that could lead to clogs.

How to Prepare Your Drip System for Winter?
Drip irrigation systems are designed to be left in place for years, so it’s no surprise that you will want to protect your investment by winterizing your system. Winterizing a drip system involves draining the water from the drip pipes and removing any dead vegetation around the sprinklers. This can keep them from freezing over the winter and causing damage when they thaw.
To winterize a drip system:
- Drain all water from the lines by opening a valve located near each sprinkler head or on the main line leading into your house. If no valve is available at each sprinkler head, open up your main line leading into your home instead of draining individual lines (be careful not to drain too much). Allow all water to drain completely before continuing with this process. If necessary, use buckets or other containers to help catch any excess liquid flowing out of these openings.
- Remove all dead vegetation around each sprinkler head or along the main lines leading back into houses. This will prevent them from freezing over during cold nights—and collect any debris with rakes or pitchforks before setting up an ice melt barrier around each area where plants have been removed.
- If you have an automatic sprinkler systemat your farm, you will need to switch it from “Automatic” to “Manual” mode so that it does not come on during winter. You can do this through your home’s control panel. This will prevent any damage caused by water freezing inside your pipes when temperatures drop below freezing.
Drip Irrigation Maximizes the Efficiency of Water Use
Drip irrigation can save you a lot of money and time, especially if you are growing crops on a large scale. With conventional sprinklers, it’s difficult to apply water directly to the root zone where it is needed most. However, drip lines can be placed very close together with drip irrigation because each one uses such a small amount of water at a time. That means less water is needed and less labor is required to install and maintain the system.
Drip irrigation systems are also much more precise than sprinkler systems. With drip lines, you can direct the water exactly where it is needed most—in this case, to the root zone of your plants.
Drip irrigation is a great way to improve your garden and keep it healthy. It can make watering your plants more efficient, as well as reduce the amount of time you spend doing this chore.
