Exploring the Benefits of Subsurface Irrigation Systems
Looking for an efficient way to water your garden while conserving water? Subsurface irrigation systems might be the answer. These innovative systems deliver water directly to the roots of your plants, ensuring they get the moisture they need without waste.
In this blog, we’ll explore what subsurface irrigation systems are, how they work, and why they’re a great choice for homeowners in Bedford, TX, Euless, TX, and Grapevine, TX.
What are Subsurface Irrigation Systems?
Subsurface irrigation systems are a method of watering plants directly at the root level, beneath the soil surface. This type of irrigation minimizes water loss due to evaporation and ensures that plants get the right amount of moisture where they need it most.
It involves a network of buried tubes that deliver water directly to the plant roots. By using this system, you can achieve efficient water usage and promote healthier plant growth.
How Subsurface Irrigation Works
It’s pretty simple. Water from a main source flows through a series of drip tubes laid out beneath the soil. These tubes have tiny holes or emitters that release water gradually.
As the water seeps into the ground, it directly nourishes the plant roots without wetting the surface, making it a highly efficient method that reduces water waste.
Key Components of Subsurface Irrigation Systems
Mainline and Lateral Drip Tubes
The mainline and lateral drip tubes are the primary conduits that transport water from the source to the plants. The mainline is the central pipe that delivers water to various areas of your garden.
Lateral drip tubes branch off from the mainline and distribute water directly to the plant roots. These tubes have emitters or small holes that release water slowly and evenly into the soil.
Pressure Regulators and Control Valves
Pressure regulators and control valves are crucial for managing water flow and pressure within the system. Pressure regulators ensure that the water pressure remains consistent, preventing damage to the drip tubes and emitters.
Control valves allow you to adjust and manage the flow of water to different sections of your garden. Together, they help maintain an efficient and effective irrigation system.
Filtration Units
Filtration units are essential for keeping your subsurface irrigation system running smoothly. They remove debris and particles from the water, preventing clogging of the emitters and tubes.
This ensures that water flows freely and reaches the plant roots without obstruction. Regular maintenance of filtration units is necessary to maintain the system’s efficiency and longevity.
Fertilizer Injectors
Fertilizer injectors allow you to deliver nutrients directly to your plants through the irrigation system. These devices mix fertilizers with the irrigation water, ensuring even distribution to the plant roots.
This method of fertilization is efficient and can help improve plant health and growth. Using fertilizer injectors can save time and effort compared to traditional fertilization methods.

The first step is to prepare your site and analyze the soil. Begin by removing any debris, rocks, or weeds from the area where you plan to install the system. Conduct a soil analysis to understand its texture, composition, and drainage capabilities.
This information will help you determine the appropriate type of irrigation system and ensure optimal water distribution.
Laying the Mainline and Drip Tubes
Once your site is prepared, it’s time to lay the mainline and drip tubes. Start by placing the mainline pipe along the central area of your garden. Next, lay the lateral drip tubes, ensuring they branch out evenly from the mainline to cover the entire planting area.
Make sure the tubes are buried at the recommended depth, usually a few inches below the soil surface, to ensure efficient water delivery to the plant roots.
Connecting to Water Sources and Installing Valves
After laying the mainline and drip tubes, connect the system to a reliable water source. This could be a garden hose, a rainwater collection system, or a dedicated water supply.
Install pressure regulators and control valves to manage the water flow and pressure within the system. These components are crucial for maintaining a consistent and efficient water supply to your plants.
Testing and Adjusting the System
The final step is to test and adjust the system. Turn on the water supply and check for any leaks or blockages in the tubes and emitters. Ensure that water is being distributed evenly and reaching all parts of your garden.
Make any necessary adjustments to the pressure regulators and control valves to optimize the system’s performance. Regular testing and maintenance will help keep your subsurface irrigation system running smoothly.
Types of Subsurface Irrigation Systems
Subsurface Drip Irrigation (SDI)
Subsurface drip irrigation (SDI) is a widely used method where drip tubes are buried below the soil surface. These tubes have emitters that release water directly to the plant roots.
SDI systems are highly efficient, reducing water loss due to evaporation and runoff. They are ideal for a variety of crops and landscapes, providing consistent moisture levels and promoting healthy plant growth.
Subsurface Textile Irrigation (STI)
Subsurface textile irrigation (STI) uses a special fabric or textile material buried beneath the soil to distribute water. This fabric acts as a water reservoir, slowly releasing moisture to the plant roots.
STI systems are particularly effective in sandy soils, where water retention is a challenge. They offer a sustainable solution by reducing water usage and improving soil moisture management.
Buried Clay Pot Irrigation
Buried clay pot irrigation involves using porous clay pots buried in the soil near plant roots. These pots are filled with water, which seeps through the porous walls and hydrates the surrounding soil.
