The Problems of Traditional Rotary Head Sprinklers

When it appeared on the market 40 years ago, the modern rotary sprinkler setup was great. It allowed for lawns to be watered automatically from sprinkler heads that can disappear into the ground.

And while all sorts of other technologies have grown by leaps and bounds since then, irrigation technology has changed very little. The systems have become more automated. They use controllers to schedule watering and “smart” sensors to shut them off when it’s raining.

But the rotary sprinkler heads still have the same inherent shortcomings they had four decades ago.

Facing Facts

Recently, we discussed sprinkler system technology with Jarod Roberts, irrigation contractor and owner of Westside Sprinkler located in Colorado (where IrriGreen has been getting a lot of attention lately).

We asked what problems he has with traditional irrigation systems.

“Rotary head coverage. You can vary the length of the throw and the speed of rotation, but with single streams, rotary heads just do not cover evenly. You have to overlap sprays and overwater some parts of a zone for the entire area to get enough.

“The industry has gone through several generations of rotary heads, and homeowners seem to love them when you put them in. But, when they end up with those bulls-eye patterns of brown and yellow across their lawns, they want them out and replaced.”



A rotary head can get water on most of the lawn, but not evenly, leaving some parts under-watered. The most common way to solve the issue to use more water, resulting in overwatering and water waste. The situation gets even worse when dealing with more complex lawn layouts.

Roberts continues:

“With the basic limitations of mechanical technology, the only way for conventional systems to address coverage issues, or challenges with tricky lawn shapes, is to put more product in the ground – additional laterals, more valves, more heads. One type and size of head here, a different one there. More and more product means more complexity and more performance problems and maintenance headaches, and still does not address the critical problem: the water coming out of the heads does not water efficiently and effectively.”

Now, in addition to water waste, a contractor is dealing with extra parts and more labor as they try to compensate for the shortcomings of traditional sprinkler heads. All of this lead Roberts in a search for a better irrigation system.

With help from he found the IrriGreen Genius® Irrigation System.

Changing the Game with IrriGreen

Rather than using a one stream system like traditional heads, an IrriGreen nozzle features 14 different size holes to distribute water at different lengths in varying amounts. The result is an evenly watered lawn with fewer sprinkler heads needed.

We asked Roberts what he thought about the advantages of IrriGreen.

“It solves issues in addition to better coverage. With only one head per zone, less pipe and less wire, fewer valves, fewer fittings, there is less disturbance of the landscape during installation, much less work for me and my guys, and less to go wrong after we leave.”

With help from CPS distributors, inc., he found the IrriGreen Genius® Irrigation System.

Jarod Roberts is just one of many irrigation contractors seeing the distinct advantages of the Genius® Irrigation System. If testimonials aren’t enough, the Center for Irrigation Technology (CIT) just released the results of comparative testing between IrriGreen and traditional sprinkler systems.

In the end, our Genius® system produced the same results with 40% less water used.
