Outdoors:

Up to 70% of California’s entire residential water supply is applied to home landscapes, yet many landscapes are overwatered due to sprinkler controllers that are not programmed properly. Some Southern Californians are now using smart sprinkler controllers that water based on plant needs. These controllers automatically adjust for changing weather conditions, thereby reducing waste and runoff. Learn about rebates for weather-based irrigation controllers below.

Note: Some local water agencies add funding to the baseline rebate amount. Consult the Estimate Your Rebate feature to find out if your water agency is on the list.

Weather-Based Irrigation Controllers (WBICs)
  • Automatically adjust the irrigation schedule to account for changing weather and plant types;
  • Save over 13,500 gallons of water per year!
  • Rebates start at $80/controller for less than 1 acre of landscape; $35/station for more than 1 acre.
  • Apply water more slowly and uniformly to prevent over-watering and encourage healthy plant growth;
  • Use 20% less water than conventional spray heads!
  • Rebates start at $4/nozzle; minimum quantity is 15 nozzles.

Rain Barrels

Collecting and re-using rainwater from gutters and downspouts for lawns and gardens minimizes the amount of water flowing into your storm drains, sewer systems and local waterways. Plants and microbes prefer rainwater because it is naturally “soft” and free of chlorine, fluoride and other chemicals.

Soil Moisture Sensor Systems

A soil moisture sensor measures soil moisture content in the active root zone on your property. The sensor should be placed in a location that best represents the overall soil moisture condition of the site, and must be connected to an irrigation system controller that accepts a signal from the sensor. A measurement is taken before each scheduled irrigation event, and the irrigation controller bypasses the scheduled run cycle if the soil moisture is above a certain threshold level defined by the user.

Turf Removal

(customers of participating water agencies only)
  • Replace irrigated lawn with drought tolerant plants or other approved landscape options
  • Rebates available at $2 per square foot of turf removed
