On the factors influencing public knowledge and acceptance of reclaimed water from a survey of three cities in northern China

In this study, we analysed the survey results regarding the level of public knowledge about, and general attitudes towards, reclaimed water in Jinan, Weifang, and Yantai, three cities in northern China that experience serious water shortages. The objective is to identify the factors influencing public knowledge and acceptance of reclaimed water and determine the hurdles of water reuse applications. The results showed that: (1) educational background was moderately correlated, and age and monthly income were weakly correlated, with the respondents' knowledge about water resources and use; (2) gender, occupation, and economic income were not related to public attitudes toward reclaimed water, and older people and those with higher educational backgrounds were more willing to accept the use of reclaimed water than were other respondents. This study could provide a valuable reference in other regions of China and developing countries facing similar issues of reclaimed water. The knowledge of this study will help to overcome public acceptance hurdles in other projects.
