Even in this day and age, we come across many farmers that are not well informed about the makings of an irrigation system, let alone how to be cost efficient. This is not an issue however, because we would like to help you with both of these issues!

To design a great irrigation system, it takes a lot of knowledge about irrigation as well as all of the involved equipment including pipes and pumps. Our designers specialize in center pivot, lateral move systems, pipes and pumps. We use an highly specialized irrigation design software that is also capable of handle the design of a water distribution system. The software uses Google Earth data to create topographic maps of the land at question. We ask our customers to send us a map of their land using Google Earth via a KML file. Having this resource allows us to include key elements such as elevation, boundaries and water sources, all at an extremely low cost. Surprisingly, Google Earth (based on satellite imaginary) is usually more accurate then a traditional land survey and it is certainly a lot more cost effective.

Elevation differences in the land are then used to calculate water pressure as well as the underground pipeline size. These calculations are done automatically, making this program some of the most advanced software available to irrigation design companies!

An example of a Google Earth, kml file. Here we can see fields represented by three boundaries from separate farmers that are working together to save on their investment. The red lines represent the channels under construction that will lead to the field where a dam will be built.

There are many designers who design and place irrigation circles in an incorrect manner, leaving huge amounts of wasted land between pivot circles. Some might place an end gun at the end of a pivot, but this is clearly a minimal improvement when compared with a properly designed system. Certainly more equipment is needed to implement a proper irrigation design, but our designs will return investments far quicker than any conventional design. Farmers want to make money, and wasted land is wasted crop production. See an example of a conventional, inefficient system below.

Conventional design with wasted land between pivots

Correct design that uses land to its maximum capabilities. Using end guns, we are able to irrigate nearly all of the remaining land.

Effective Placement
When our designers consider the placement of center pivots, they look as where land may be wasted between pivot rotations and how best to reduce that waste. End gun at the end of pivots is one way to help reduce the chance of unirrigated land; more machines or a combination of different systems is another way. Our goal is to help farmers be able to use as much as their land as they can for crops. Check out the example below.

Long term savings
The best way to save money is to consider a project from start to finish, including the quality of the materials, placement of pivot, and long-term cost-effectiveness. Our designers consider all options, using data about the distance and hydraulic systems to find out where money can be save long-term. For example, designing for lower pressure in pumps is more cost-effective as the pumps in the pump station will be small and cheaper. Our designers will run each plan through the program’s hydraulic simulation to find any error before proceeding.

Turnkey Projects
The more people and companies involved in a project, the costlier the project may become as everyone wants to make their profit. By providing turnkey projects, we can offer competitive prices and more free services. We will also be more knowledgeable about your needs and able to offer more personalized and better irrigation solutions.

If you do buy your equipment from different suppliers, you should talk to the center pivots manufacturer first and make sure that all equipment will work together. The best way to find manufacturer of valve, pumps and pipes is to consult your pivot manufacturer.

Advance software
We use the best software for irrigation design on the market to calculate pipe sizes and pump pressures, run hydraulic simulations, find water application rates and even give GPS points for center pivot. It can calculate the end pressure of center pivots, inlet pressure, water harmer protection, friction loss in pipeline and the pressure on each valve. Then the program will design an irrigation plan, which we will test with survey work for higher accuracy. Compared to traditional land surveys or older programs such as Autocad, this software saves time and money and is also for more accurate.

Consistent Materials
Many manufacturers use different sizes of spans, diameters of pipelines, gooseneck spacing and overhang sizes. Our designers use the actual sizes of equipment we provide. If you want to create an irrigation design using another manufacturer’s machines, our designers will need to rework the design with the correct pipelines, however are free of charge, and we supply all the irrigation equipment, center pivots, pipes, pumps and valves from our long-term partners in China.
