Weather-based irrigation controllers can reduce water use outdoors. Unlike standard timers that turn on sprinklers at set intervals, “smart” controllers use weather data and site information such as plant type and sprinkler system output to adjust watering times and frequency. Professional installation is recommended because proper set-up usually requires knowledge of soils, precipitation rates, slope and other landscape characteristics.
Incentives from SoCal WaterSmart start at $80 per controller for residential sites with less than one acre of landscaping. For larger residential sites, incentives start at $35 per station. Rebates cannot exceed the purchase price of the controllers.
