Local Resident Perceptions of Water Reuse in Northern Utah.

The reuse of municipal wastewater is increasingly implemented in cities to mitigate intensifying water supply problems. Public acceptance of water reuse is integral to successful implementation. This study uses survey research to explore local perspectives and uses of secondary (non-potable) water for irrigation in two northern Utah cities - one that has implemented water reuse and one that has not. Findings revealed few differences between cities, suggesting that experience with water reuse may not influence acceptance or risk perception levels as long as it is limited to certain less direct purposes. In line with previous research, general support was found for water reuse for irrigation with relatively low health risk perceptions. Water reuse support was higher (and health risk perceptions lower) for those agreeing with the environmental and economic responsibility of water reuse. Having heard of water reuse was not related to health risk perceptions in either city. However, in the city with water reuse, those more familiar with the system had lower health risk perceptions and higher levels support for reuse for irrigation. Results suggest public acceptance of water reuse may not always be a barrier to local implementation, though continued communication about water reuse systems is important.
