How To Design Sprinkler Irrigation System?

How to design a sprinkler system?

1. Determine the flow rate and water pressure

First of all, you need to decide from which source you want to get the water for your irrigation line and then calculate the flow rate and to water pressure of that source to determine how many sprinklers you can have on the line.

To find the water pressure, you can simply use a water pressure testing gauge and attach it to the spigot of your water source (for example, the hose). To find the flow rate, you can grab any bucket that you have then turn the water from your source on fully. While waiting for the water to fill the bucket to the top, record how long it takes to do so.

Once you finish, multiple the size of the bucket (in gallons) by 60 seconds. Divide everything by the time the water source takes to fill. And there you go, that result will be the flow rate (in gallons per minute).

2. Choose your desired type of sprinkler heads

There are many types of sprinkler heads with different water pressure, flow rate, and coverage. Some sprinkler heads can rotate, and others cannot.

There are actually 3 different types of sprinkler heads, which are based on how the water will be distributed to the plants.

• Spray heads:?These are also called the?fixed spray heads?that release water to the outside in a fan-shaped pattern. Their coverage is pretty low as they can be only placed up to 18 feet’s apart. To operate properly, they need 20 to 30 PSI of water pressure.

• Rotors:?They will not be fixed like the first type, but rotating. One of their examples is the Rain Bird Sprinkler. This sprinkler head has a pretty high coverage. Two heads can be put from 8 to 65 feet apart, so make sure you look at the information for your chosen model before purchasing. The rule for determining the right sprinkler head for a specific water pressure is the water pressure at the rotor head in (PSI) must exceed the distance (feet) between the heads.

• Rotary Nozzles & Rotators:?They work exactly like the rotors, but they appear to be much smaller. They are considered more efficient than other types since they produce less evaporation of water before it reaches the ground. Their radii usually range from 15 to 35 feet.

When you are done choosing the sprinkler head, you can check its water pressure and flow rate on the manufacturer's website. Compare those numbers with your water source's figures to determine how many heads you can install on your irrigation line.

3. Determine the layout of sprinkler system

Think about the layout of the waterflow is a critical part before you start connecting the pipe.

You have to decide where you want to install your irrigation line. By doing this, you know where to dig a trench to bury the line. And you know how long the line needs to be to cover your desired zone. Usually, the depth of your irrigation line underground ranges from 8 to 12 inches.

As you finally choose areas to put your sprinkler line, you can start trenching soil, which is going to take you a long time if the soil is dense.

Micro Sprinkler irrigation

Whether you’re watering your lawn or farming, it’s important to use water efficiently. That’s why micro-sprinkler irrigation has become so popular. With this system, crops get the water they need when they need it. Among different?types?of sprinkler irrigation systems, micro-sprinkler irrigation is the right tool for the job.

Compared to drip irrigation, micro-sprinkler irrigation is perceived as a less capable or efficient method. However, this system is a smart and efficient way to disperse high volumes of water efficiently.

Features of Micro-Sprinkler Irrigation System

• This low-pressure system, which uses medium to low irrigation volumes, is suitable for seasonal and high-value crops.
• It can increase yields while decreasing water, fertilizer, and labour use if managed properly.
• Micro-sprinkler irrigation is highly efficient at applying and uniformly distributing water with little to no wastage.
• It is ideal for irrigating irregularly shaped or sloping fields that can’t be furrowed or flood irrigated.
• Many irrigation companies in Toronto add fertilizer injection to the system for an additional increase in its efficiency.

Advantages and Disadvantages

Micro-sprinkler irrigation allows both localized and full-surface irrigation. Compared to drip irrigation, it can get a larger volume of soil wet, which makes irrigation management a lot easier. Also, there are more visible emitter blockages in this irrigation system.

But chances of evaporation loss and runoff from the soil surface and during water application are higher. Plus, you can’t work in the field during active irrigation and it costs more to maintain.

Because its emitter can be damaged easily, it’s important to inspect the micro-sprinklers from time to time, either yourself or by hiring a company.

It is important to inspect this system regularly and check your fields for moisture levels at different depths. This will tell you if the area is getting too much or too little water.

Picking The Right Sprinkler: 5 Things to Keep In Mind

When your investment and efforts depend on giving your plants what they need, micro-sprinklers are often the right tool for the job. But you must keep certain things in mind before picking a sprinkler.

1. ?Make sure the flow rate of the sprinkler matches the soil’s infiltration capacity. For heavier soil, it is best to stick with lower flow rates. It will also bring out the hydraulic and ergonomic benefits of longer irrigation and fewer shifts.
2. Check the manufacturer inspection and compare sizes to match the wetted perimeter to the root zone size. Use a micro-sprinkler with a two-stage swivel. When the tree is young, a small deflector keeps the water close to the tree, avoiding water and fertilizer wastage. As the tree grows, simply break off the deflector and the wetted perimeter will grow to fit your wider root zone.
3. Insects entering the nozzle can stop your micro-sprinkler from rotating properly, so look for one with a pop-up rotor that protects it from insect penetration.
4. Applying water and nutrients in a uniform way is critical for high-value crops, so using a pressure-compensated micro-sprinkler is highly recommended. These micro-sprinklers make sure all your trees are irrigated and fed equally, even on extreme slopes.
5. Using unreliable sprinklers can damage your investment with its poor performance, so always look for a micro-sprinkler with a proven track record in the field.

Designing A System for Micro-Sprinkler Irrigation

Irrigation companies in Toronto design the entire system around the water requirements of a specific crop. They take the highest water requirement value year so that the water supply is sufficient during that time of the year well.

1. Determining the Irrigation Areas : The effectiveness of the entire system depends on determining your irrigation areas and then choosing the?micro-sprinkler?and drippers accordingly. Each irrigation area will have its own pipe with similar drippers or sprinklers. In an end-to-end line, the drippers help reach the plants in the middle of a rectangular or square plantation area.
2. Calculating Water Flow : Before you buy the parts, know the flow and pressure of the water in the area. This will establish the number of sprinklers you can operate at the same time. The number of drippers should not exceed the maximum water flow capacity of the irrigation zone.
3. Determining the Soil and Water Quality : If the soil has high salt levels, irrigating with high pH can impair the ability of the tress to absorb key micronutrients. The high pH levels in soil and water can be neutralized by injecting acid into the irrigation water with a fertilizer injector. Determining the quality of water and soil will help you know if you need a fertilizer injector in your micro-sprinkler irrigation system.
4. Getting the Parts : After the irrigation company has determined the areas of irrigation and determined where your pipes and sprinklers will go, they will?get the products or parts?for you. The parts should be of good quality and have a proven track record. Ask the company what parts they are providing and read the reviews. Micro-sprinkler irrigation systems can be very beneficial if they are set up correctly. However, it can be easily damaged so you’ll need to pay attention to it. Many Irrigation company, will help you with its repair and maintenance.
