海湾合作理事会国家的年降雨量很低，地下水资源日益枯竭，是世界上最缺水的国家之一，依赖越来越多的淡化水和经处理的污水来满足其日益增长的用水需求。在卡塔尔，政府大力补贴海水淡化和再处理过程，但该国的人口增长加上其557升/天/居民的高用水率导致补贴成本增加。这些费用是政府的一个担忧，特别是在2014年油价下跌后，政府试图削减成本。几乎没有处理，灰水（即从淋浴，游泳池，空调机组等轻轻使用的水）可替代更昂贵的TSE或脱盐资源，用于几个基本用途，如酒店和新公共建筑（如清真寺、大学、游泳池）的景观美化或厕所冲洗。这项研究提出了在卡塔尔的一项全国性调查的结果表明，该国的人口可以高度接受灰水回用取决于人们如何介绍灰水的好处。这项研究发现，将灰水回用作为一种节约成本或节水措施的框架在卡塔尔国民和外籍人士中获得了最高的接受度。
With very low annual rainfall and increasingly depleted groundwater resources, the Gulf Cooperation Council (GCC) countries are some of the most water scarce in the world and rely on growing quantities of desalinated water and Treated Sewage Effluents (TSEs) to meet their ever-increasing water demand. In Qatar, the government heavily subsidizes the desalination and retreatment processes, but the country’s demographic growth coupled with its high water consumption rate of 557 liters/day/inhabitant has led to increasing subsidy costs. These expenses are a concern for the government, especially as it tried to cut costs after the 2014 fall in oil prices. With little treatment, greywater (i.e. gently used water from showers, swimming pools, AC units, etc.) can replace more expensive TSEs or desalinated resources for several basic purposes such as landscaping or toilet flushing in hotels and new public buildings (e.g. mosques, universities, swimming pools). This study presents the findings of a national survey in Qatar that reveals that the country’s population can be highly accepting of greywater reuse depending on how people are introduced to the benefits of greywater. This study found that the framing of greywater reuse as a cost saving or as a water conservation measure generates the highest acceptance among both Qatari nationals and expatriates.
