Why Use a Smart Irrigation Controller?

For the typical homeowner,  70% of water usage is utilized for their landscape and they overwater by 50% or more.  We’ve gone to great lengths to install low flow shower heads, toilets, faucets, etc.. then we waste thousands of gallons per week on our landscape.

How did we get here?  The original  irrigation controllers were designed to be basic “set and forget” timers for for each zone.  You arbitrarily set each zone to 20 minutes, 5 times a week then forget about it.  If one zone looks brown then you might increase the time of that zone (or maybe all the zones) and forget it again.  When water was cheap and plentiful using a bit extra didn’t seem to matter much as long as our grass was green and healthy.

Of course the amount of water your landscape needs to remain healthy is much more complex than just 20 minutes, three times per week, year round.  Water needs are different based on soil type, plant type, slope, temperature, humidity, rainfall, solar radiation and more.  Only now are we starting to realize how much water can be saved with “smart” irrigation controllers that take all these variables into consideration.


Smart irrigation controllers leverage the latest technology to ensure your landscape receives the precise amount of water based on a number of factors including plant material, soil type, slope, sprinkler type, temperature, humidity and rainfall.

We believe the most accurate smart controllers combine on-site weather data with site information to calculate watering times based on evapotranspiration or ET, the sum of evaporation and plant transpiration. Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and waterbodies. Transpiration accounts for the movement of water within a plant and the subsequent loss of water as vapor through stomata in its leaves.

Sounds simple enough, right? Fortunately, the smart people at Weathermatic, the leaders in smart irrigation technology have made it easy with the SmartLine irrigation controller.  We input your zip code, plant type, soil type and slope then it combines that data with the on-site weather station to calculate your precise watering time per zone. With over 200,000 SmartLink units installed around the world, the SmartLine has proven to reduce irrigation water usage by 20% to 50%.

Tired of adjusting your controller throughout the year and guessing how much you need each month?  Now you can let SmartLine handle the adjustments for you based on the on-site weather station and calculated needs of your plant and soil type.  Essentially, this sprinkler controller automatically adjusts itself every day – 365 days per year.

Combined with our water management service we’ll supercharge the controller by monitoring and tweaking it remotely to further optimize your water savings.  We’ll also receive alerts and respond in a timely manner if we see any issues.
