Smart irrigation systems are relatively new technologies that optimize irrigation schedules in residential landscapes, thus leading to reduced irrigation water use and potential contamination. To promote the use of such technologies, the landscape services industry has introduced innovative features such as the integration of local weather data into irrigation controller systems or mobile phone control and alert notifications that help to facilitate usability and prevent over-irrigation. Very few studies have addressed homeowners’ preferences for outdoor irrigation technologies. This study investigates homeowners’ preferences for smart irrigation systems for residential landscapes. We utilized online survey data to examine how homeowners’ knowledge and perceptions influence their preferences for specific features such as automatic failure alert and notifications, mobile control, integration with weather-based and soil-moisture sensor-based irrigation, home automation, and touchscreen displays. Results estimated by the rank-ordered logit model revealed that knowledge and perceptions of smart irrigation controllers are significantly correlated with homeowners’ preferences for water efficiency features. The results offer practical implications for policymakers and the residential irrigation industry as they develop and promote smart irrigation technologies to conserve water resources.
