When you think about the different ways to water your lawn, what comes to mind? For many people, it’s probably a set of sprinklers that pop out of the ground or even a good old-fashioned garden hose. However, drip irrigation systems are another option—and they’re more efficient and eco-friendly than many other watering systems. Below, we’ll explain what a drip irrigation system is, how it works, and how it compares to other irrigation methods.
What Is a Drip Irrigation System?
Drip irrigation is a type of low-flow irrigation system for watering your lawn or garden. It uses a series of perforated tubes (called drip lines) to slowly and evenly distribute water throughout your yard. Unlike an irrigation system with sprinkler heads, a drip irrigation system delivers water straight to the plants’ roots, creating more efficient watering sessions and minimizing water waste.
How Does Drip Irrigation Work?
In a drip irrigation system, the tubes connect to a water source, like an outdoor faucet, which provides the water that goes into the drip lines. The tubes can either sit on top of the soil (above-ground or surface drip irrigation) or slightly beneath it (subsurface drip irrigation). Water gradually drips out of the holes in the tubes (known as emitters), so your plants’ root systems receive a slow but steady supply of water.
Drip irrigation systems are easy to customize, which is ideal if you have multiple types of plants with different hydration needs. In that case, you can create separate zones and watering settings to make sure everything in your yard gets the right amount of water.
Despite the similar names, a drip irrigation system isn’t the same thing as a drip distribution system, which is a type of septic system. However, if you have an aerobic septic tank, you may be able to build a septic sprinkler system to distribute your home’s wastewater back into your soil.
How Much Does a Drip Irrigation System Cost?

The price of installing a drip irrigation system depends on a few factors, including the size of your yard, the setup and components you choose, and whether or not you get professional help. However, hiring a pro to install a subsurface drip irrigation system on an average-sized lawn usually costs between $450 and $630.
If you’re on a budget and willing to take on a DIY project, you could save some money by installing your own system. Above-ground drip installation kits cost as little as $20 per 100 linear feet at home improvement stores.
Drip Irrigation vs. Other Watering Systems
While drip irrigation may work well for some homes, it might not be the best option for your property. Here’s how this watering system compares to other common irrigation methods.
| Type of System | Description | Cost |
|---|---|---|
| Drip irrigation | Controlled, automated watering directly on plant roots | $450–$630 |
| Automatic sprinkler | Zoned watering that covers large areas of landscape | $1,600–$3,600 |
| Underground sprinkler | Automatic sprinkler system with sprinklers buried in trenches underground | $1,700–$3,400 |
| Soaker hoses | Large-scale drip irrigation using just one hose | $50–$500 |
Drip Irrigation System Pros and Cons
If you need guidance on choosing a watering system, weighing these drip irrigation pros and cons can help you decide.
| Pros | Cons |
|---|---|
| Even, controlled watering | Higher up-front cost |
| Automated | May require pro installation |
| Reduces water waste | Regular maintenance |
| Limits soil erosion | Aboveground tubes vulnerable to weather and UV |
| Reduces plant disease risk | Vulnerable to pests and chemicals |
DIY vs. Hiring a Pro
If you’re a hands-on person, you can learn how to install drip irrigation yourself and knock out the project in an afternoon. It’s a pretty approachable six-step DIY task that includes mapping out a grid plan for the system, laying and cutting a main hose and feeder lines, and punching holes in the tubes.
With that said, there are some cases in which you might prefer to call an expert for drip irrigation installation. For example, if you have a sizable yard or a plant garden with special watering needs, you can save quite a bit of time, hard work, and hassle by reaching out to a local sprinkler installation pro. They’ll work with you to determine the best drip irrigation system for your space, whether that’s an above-ground or subsurface type.
