Smart Irrigation Controllers
Purchase and install a weather smart controller for a $75 to $125 rebate, or more for large sites.
What are weather-based irrigation controllers?
Weather based irrigation controllers, also known as smart irrigation controllers, use current weather information to create appropriate irrigation schedules that adjust as the weather changes.
Why should I get a weather-based controller?
Weather based irrigation controllers provide accurate irrigation schedules that adjust to account for daily weather changes.
What is the rebate amount?
The District is offering a $75 to $125 rebate for the purchase and installation of a weather-based irrigation controller. The $75 rebate is for controllers that are sensor based and do not have an associated signal fee (see next question for signal fee). The $125 rebate is for controllers with an associated signal fee. Larger areas (HOAs, parks, etc.) may qualify for a $600/irrigated-acre rebate.
How do weather-based controllers work?
There are two types of controllers:
- Signal-based: rely on daily weather updates received from satellite signals or require an internet connection to receive the information ($125 rebate).
- Sensor-based: use on-site weather or solar sensors to create irrigation schedules ($75 rebate).
NOTE: A system that works based solely on a rain shutoff sensor is not sufficient to qualify for this rebate.
Are they right for all landscapes?
Consider your landscape size and type and your current watering practices. Weather-based irrigation controllers are most cost-effective for medium-size or larger landscapes, however they will work for any landscape. They also work well for vacation homes or homeowners who do not want to continually adjust their irrigation controllers.
Do they really save water?
Weather-based irrigation controllers are proven to reduce landscape water use on average by 8% in well-maintained irrigation systems. However, weather-based irrigation controllers cannot correct things like overspray, irrigation system leaks, or poor design. To really benefit from a weather-based controller, you should have a properly designed and maintained irrigation system, or be willing to make repairs and changes to your system if it is not working well.
How much do they cost?
Prices vary according to the type and level of sophistication, and the signal-based controllers have an ongoing signal fee. Prices start around $175 for the simplest type. They are more expensive than the typical controllers used today. However, with the District rebate and water savings, the controller can pay for itself over time.
Which weather-based controller should I choose?
There are several types on the market today. A landscape professional may be able to help. Feel free to contact Roy Sikes, the District’s Water Conservation Specialist, at 831 475-8501 ext. 146 for information.
