Abstract
In this study, we derived seven customer value factors to evaluate the levels of service in wastewater utilities required by customers. Levels of service according to the customer value were categorized into environmental amenity, accessibility of wastewater service, affordability of wastewater charge, quality of wastewater service, health and safety of wastewater service provision, reliability and responsiveness of wastewater service provision, and satisfaction of customer service. To investigate the levels of wastewater service, questionnaires were prepared according to the customer value factors, and the questionnaire survey was performed with 800 adults in all over Korea including male and female samples. The comprehensive satisfaction score for the wastewater service was 57.5 points, indicating a slightly good satisfaction level. The detailed analysis of the result showed that the satisfaction level was high in the wastewater service accessibility and call center service provision but it was relatively low in the river water quality and nasty smell of wastewater. It was concluded that the quality of wastewater service and customer service satisfaction need to be elevated primarily in order to improve levels of wastewater service required by the customers.
