By conducting a questionnaire survey with the city's inhabitants and studying related documents, this paper tries to find out the reasons that hinder the use of rainwater from the inhabitants’ perspective. Based on the paper's findings, the actions and solutions towards increasing the use of rainwater for domestic purposes are recommended, mainly for the city's inhabitants.
