Lawn Drip Irrigation System

Drip irrigation system is widely used these days for watering flower beds, landscape plants, and vegetable plants. Now, keeping in mind the different irrigation requirements, drip systems have been modified to meet varied watering needs. You can utilize drip irrigation for lawns as well.

Until now, sprinklers were used for irrigating lawns. But with recent experiments and innovations in drip irrigation, now you can irrigate your lawn using drip systems. The things can me made easier using sophisticated emitter lines. Let’s go little deeper how you can use lawn irrigation systems for better watering.



Emitter Lines for Irrigating Lawns

Emitter lines play a key role for nourishing lawns and therefore, it is of great interest to know about how emitter lines should be planned out. They are made of polyethylene tubing. You have to insert drip emitters in your line at some intervals. Basically, such emitter lines are used for irrigating all sorts of plants but most agriculture experts and irrigation specialists have experienced that it can work better for lawns also.

In recent times, most independent researchers recommend to use emitter lines for watering lawns. The researchers at the Center for Irrigation Technology at California State University Fresno are of the same opinion that emitter lines can be used for lawns for better results.

Benefits of Using Drip Irrigation for Lawns

One of the major benefits of sub-surface irrigation is saving water. Using this irrigation method, water is delivered below the soil surface and there is no fear of water being lost due to water runoff or evaporation. Please remember that emitter lines play a crucial part for watering lawns. Suppose you have to water uneven or narrow strips of lawn, emitter lines will be of immense advantage. When you water your lawn with the help of emitter lines, you do not have to worry about rotting and water stains of fences as well as slippery walkways because all these things are caused online when you do overshooting lawn boundaries.

Please remember that there are great benefits if you keep lawn surface dry. The risk of disease can be reduced when you keep your grass dry and all are possible when you make use of a well designed drip system.

You can set your emitters with different spacing when it comes to making subsurface systems. Such systems can be best for slopes which can help you avoid wet spots at low points and dry spots at the top positions.

Researches have shown that weed assault can significantly be reduced or eliminated in healthy dense turf that is irrigated underground because there is no moisture on the surface that can encourage seed germination. Although, subsurface drip systems for lawns are much more efficient, you can avoid their use if your lawn has large trees around with big roots or the soil is porous. But for irregularly shaped lawns, nothing can work better than emitter lines of drip irrigation system.

How to Set Up Your System

When you think of making emitter lines, please note that they can have pressure- compensating emitters or either turbulent flow emitters. Pressure- compensating emitters can be best suited for slopes or hilly terrain whereas turbulent flow emitters can be used for wide channels so that there is no risk of debris clogging them. It is up to you which one to choose but for the most part, turbulent flow emitters will be best.

The basic thing for designing a drip system for your lawn is to set parallel emitter lines that run from your supply line to an exhaust line. Please remember that for the most parts, exhaust and supply lines are made up of PVC and as you know that a PVC system is always easy to install and durable in nature.

It is easy to install emitter lines in a new lawn. You can also install them in your existing lawn with some little efforts with the help of trenchers. You need to carve 1 inch wide and 5 to 6 inch deep trenches. You have to set your emitter lines at the bottom and then the trenches are filled in.

According to the shape of your lawn, you can design your emitter lines. Please remember that they should go parallel to one another. According to the soil type, you need to determine the flow rate of your each emitter you have placed, and you have to consider the spacing between emitters on the line.

Normally, for clay soil you may consider using 1/2-gph emitters spaced 18 inches apart with lines spaced 18 inches apart. And for sandy soil, you may think of using 1-gph emitters spaced 12 inches apart on lines 16 to 18 inches apart. These are just general considerations you may consider while installing and using drip irrigation for your lawn.
