As an important alternative water resource, rainwater harvesting has drawn much attention in many areas. To encourage the installation of a rainwater harvesting system, Tucson Water has provided rebates since 2007. This study focuses on a desert city in Arizona, where much rainwater can be harvested during the monsoon season. In addition to the state program, Tucson Water provides a rainwater harvesting rebate program to motivate people to install a rainwater harvesting system. However, it is observed that rebate adoption has been evenly distributed among different population groups. This research aims to further examine the distribution disparity and identify the factors that are associated with the disparity. The research findings provide important insights into potential revisions to the existing rebate program and can help address environment justice issues in water resource management.
