- How does a “smart” irrigation controller make watering my landscape easier and more convenient?
- Traditional sprinkler timers require manual adjustments every time the weather changes. “Smart” controllers automatically adjust the watering schedule based on local weather/site conditions. So, once the initial setup and monitoring is complete, there’s no need to reset the "smart" controller; it adjustts automatically.
- How will installing a “smart” irrigation controller save me money?
- A “smart” controller saves you money by reducing your water use. Your actual water savings will depend on how you have watered in the past. Pilot studies have shown typical water savings to be in the range of 20%-40% annually.
- “Smart” controllers also save money by promoting a healthier landscape. Landscapes that are properly watered will be less likely to suffer from fungal disease and insect infestations that can require costly treatments.
- Where can I purchase a “smart” irrigation controller?
- “Smart” irrigation controllers are generally only available through irrigation supply houses or landscape contractors. Please view our Makes and Models list to view the "smart" controllers that qualify for rebate. Click on the manufacturer links to be redirected to their websites for additional product information.
- Can I install a “smart” irrigation controller myself?
- The proper installation and initial setup of “smart” irrigation controllers generally require an in-depth knowledge of soils, precipitation rates, slope measurements, and related factors. Therefore, we strongly recommend you work with a certified irrigation contractor who is experienced in the installation of “smart” controllers. To locate a certified irrigation professional, please contact the manufacturer of your new "smart" controller.
- Once the “smart” controller is installed and running properly, it automatically takes care of seasonal weather/site specific adjustments, and does not require frequent monitoring.
- What questions should I ask before purchasing a “smart” controller?
- The Irrigation Association, a non-profit organization supporting water conservation through efficient irrigation, has published an
 Irrigation Consumer Bill of Rights to educate consumers about the questions to ask their contractor before purchasing a new irrigation system. Be sure to read it prior to meeting with your landscape professional. Before beginning any work, be sure to confirm that your contractor is specifically trained in the installation of the “smart” controller that has been selected.
- How are automatic adjustments made?
- Depending on the make and model, “smart” controllers receive the environmental data they need from various sources. Some models use data from local weather stations or on-site sensors, while other models gather information from several weather stations linked to match the zip code and address of the installation site. Each type has the capability to work equally well. Look for the type suited to the unique attributes of your home's landscape.
- How much do “smart” irrigation controllers cost?
- The cost of “smart” controllers varies according to the number of zones and features included in the controller model you select. Most range in price from a few hundred dollars on up, plus installation. In addition, some weather station-adjusted controllers require a small monthly or annual fee for transmission of daily weather information. Other, internal sensor-based “smart” controllers rarely require transmission fees.
- Which “smart” irrigation controller works best?
- Different “smart” controllers each have different features and benefits. A certified landscape/irrigation contractor can help you make
the best choice for your specific needs.
- How have these products been tested?
- Manufacturers of “smart” controllers rigorously test their products before releasing them for sale. In addition, the Irrigation Association has recently developed an independent third party testing protocol specific to “smart” controllers. The results of these tests are available on their website. There have also been numerous field tests on various “smart” controllers. Read about some of these case studies.
- If I install a “smart” controller, will I get a discount on my water bill?
- Less water used for outdoor irrigation means less water delivered through your water meter. When you reduce water use by installing a “smart” controller, your reduced use will result in a lower water bill.
