Understanding consumer perception of drinking water can contribute to improvements in water management and consumer satisfaction. The aim of this study was to assess the consumer perception of tap water quality and other drinking water sources in Gonabad as a small semiarid city.
This study was performed in autumn and winter 2013. For collection data a researcher-made a questionnaire consisting of nine questions, based on demographic information prepared. Questions were asked for participants to provide information regarding household drinking water usage and patterns, opinion about tap water safety, taste and reasons for purchasing bottled water. For statistical analysis, analysis of variance (ANOVA) using SPSS version 16 was applied in this study.
Results showed that demographic variables had a significant relationship with consumer satisfaction (p < 0.05). Office employees, women and poor families had the most satisfaction from tap water quality. Peoples' preferences for tap water, commercial softener, domestic softener, ghanat (a type of underground cistern) and bottled water were 27.8, 19, 27.8, 40.4 and 3.5% respectively. Dissatisfaction from production of foam, unsuitable taste, unacceptable appearance and other problems in tap water was 11.1, 95.6, 27.8 and 0.4% respectively. Consumer reasons for using domestic water softeners are: suitable taste (80%), easy availability (71%), economical (56%) and low health side effects (34%).
According to these results it was clear that each consumer group, based on self-condition, prefers using a specific drinking water source.
了解消费者对饮用水的认知有助于改善水资源管理并提高消费者满意度。本研究旨在评估作为半干旱小城市的戈纳巴德消费者对自来水水质及其他饮用水源的认知。
本研究于2013年秋冬进行。为收集数据，研究人员根据所准备的人口统计学信息制作了一份包含九个问题的问卷。向参与者询问有关家庭饮用水使用情况和模式、对自来水安全性的看法、味道以及购买瓶装水的原因等信息。本研究使用SPSS 16版本进行方差分析（ANOVA）统计分析。
结果表明，人口统计学变量与消费者满意度存在显著关系（p < 0.05）。办公室职员、女性和贫困家庭对自来水水质的满意度最高。人们对自来水、商业软水器、家用软水器、加纳特（一种地下蓄水池）和瓶装水的偏好分别为27.8%、19%、27.8%、40.4%和3.5%。对自来水中产生泡沫、味道不佳、外观不可接受及其他问题的不满率分别为11.1%、95.6%、27.8%和0.4%。消费者使用家用软水器的原因有：味道适宜（80%）、易于获取（71%）、经济实惠（56%）和健康副作用小（34%）。
根据这些结果，很明显每个消费者群体根据自身情况更喜欢使用特定的饮用水源。
