Abstract
Water quantity and quality concerns in urban environments have prompted conservation groups, governmental agencies, and policy makers to develop and promote residential water conservation programs, including restrictions on residential landscape irrigation practices and incentives for the adoption of water-efficient appliances. Previous literature links household characteristics, financial incentives, and demographic characteristics to the adoption of water-efficient appliances and overall water use. However, relatively little attention has been given toward understanding how homeowners’ perceptions and knowledge of smart irrigation technologies affect their preferences or stated purchase likelihood of such irrigation equipment. To address this gap in the literature, this paper identifies perception- and knowledge-related factors that are correlated with the purchase likelihood of smart irrigation controllers. The generalized logit regression model results suggest that knowledge about irrigation systems and residential landscaping are positively correlated with purchase likelihood. Similarly, homeowners’ perceptions about conservation efforts, water restrictions, and their neighbors’ irrigation habits all increase purchase likelihood. Combined with statistically-significant correlations of several socio-demographic variables and purchase likelihood, these results have theoretical and practical implications, which are summarized in this paper.

Summary
Introduction and BackgroundSustainable water management is becoming more imperative as population growth, climate change, drought, water pollution, and economic growth have increased the demand for water [1,2]. Necessary for plant health, irrigation can have negative environmental and economic consequences when used excessively, including depleting water availability, increasing waterway pollution/contamination due to fertilizer/nutrient runoff and leaching, deteriorating turfgrass/plant health, and increasing homeowners’ utility bills [1,12,13,14]. This is concerning since homeowners often over-irrigate and their irrigation schedules frequently deviate from local irrigation restrictions [15]. The issue is further complicated by 28% of the continental U.S experiencing moderate to exceptional drought in 2016 [16]
