Rain Bird ET Manager
The New Standard in Weather-Smart Irrigation.

Although over-watering has always been something homeowners, public water agencies, property managers and landscapers tried to avoid, increasing water scarcity has brought this problem into the spotlight. No matter how efficient an irrigation controller’s watering schedule is, however, it must take into account constantly changing weather conditions – specifically evapotranspiration (ET) and rainfall.

ET is the amount of water lost from the soil through evaporation plus the plant’s water loss (known as transpiration), both of which are dramatically affected by weather conditions. Rain Bird ET Manager™ uses current weather information and ET to water your landscape only when it needs it. Since precise landscape water management is key to avoiding over-watering, the ET Manager can be an effective tool.
