Irrigation, based on science

Although over-watering has always been something people tried to avoid, increasing water scarcity has brought this problem into the spotlight.

The difference between irrigating deep and infrequently, versus shallow irrigation

No matter how efficient an irrigation controller’s watering schedule is, it must take into account constantly changing weather conditions – specifically evapotranspiration (ET) and rainfall to be truly smart. Increased watering schedule control means your irrigation system delivers water only when the landscape needs it.

Best horticultural practices recommend deep, less-frequent watering.

ET controllers do just that, through a process known as “Managed Allowed Depletion,” it allows your soil’s moisture balance to reach a user-set moisture level that increases oxygen and promotes deeper healthier root systems.


In the past, regular controllers have been set to come on for a pre-determined amount of time every watering day, regardless of the weather or season.

Zones were typically set for summertime highs and never adjusted. Unfortunately, this results in mass over watering in the spring and fall seasons. Instead, ET based controllers are constantly adjusting their run times for every zone, taking into account factors that are programmed in by our staff during the installation.  The controller evaluates the daily ET data that is sent to the controller from our weather stations. This is live (not historical) ET data that is measured specifically at your location to maximize your water savings.

You will enjoy a beautiful landscape while saving valuable time. You won’t have to worry about seasonal adjustments and severe swings in temperature or precipitation.  All with no user intervention required.

What’s involved

Installing a new ET-based controller is easy, but it isn’t as simple as replacing the old timer. A site audit would have to be performed on your site to assess your existing irrigation system and evaluate your DU.

A DU over 70% will take full advantage of the ET controller. If for some reason your system has a DU below 70% your savings may not be as high. Our technicians can suggest and offer you a quote what work would be required to bring your system up to standard.

The result: significant water savings, deeper root systems, and a healthier landscape
