灰水再利用可以大大提高饮用水系统的效率。然而，灰水回用的广泛采用取决于它是否为人们所接受。以往的研究已经评估了灰水回用技术的实施成本，并考虑了其原则上的可接受性。虽然在采用/安装该技术方面，成本显然非常重要，但对灰水再利用的实际认识对于推动使用的可接受性和该技术的长期成功至关重要。这项研究首次使用离散选择模型来量化不同社会经济群体对不同质量（颜色、气味）和不同家庭用途的灰水的偏好。一项消除安装成本影响的明确选择调查在智利圣地亚哥进行并实施。虽然立法允许在圣地亚哥使用灰水，但并没有大规模使用。结果显示，从偏好程度递减的顺序来看，人们普遍接受将高质量处理过的灰水用于冲厕所、洗衣、花园灌溉、洗手和淋浴/浴缸，但不接受用于饮用。当外观质量在颜色和气味方面变得更差时，即使那些不涉及人类接触的用途也需要金钱奖励。性别、年龄、教育水平、用水水平，特别是以前对灰水再利用的了解，是可接受性的重要决定因素，因此愿意为灰水的使用付费；然而，它们的重要性因使用类型而异。我们的研究结果为理解城市中水的快速和广泛再利用的条件提供了重要的见解，从而更好地利用有限的水资源。
Greywater reuse can allow substantial improvements in the efficiency of potable water systems. However, widespread uptake of greywater reuse depends on its acceptability by the population. Previous studies have assessed the implementation costs of greywater reuse technology, and considered its acceptability in principle. Although cost is clearly very important in terms of adopting/installing the technology, the actual perception of greywater reuse is crucial in driving the acceptability of use and the long-term success of the technology. This study uses discrete choice models to quantify, for the first time, the preferences of different socio-economic groups for greywater of different quality (colour, odour) and for different uses inside homes. A stated choice survey that removed the influence of installation costs was developed, and implemented in Santiago, Chile. Although legislation allows greywater use in Santiago, it does not take place at any meaningful scale. Results show that, in decreasing order of preference, there is an overall acceptance for using high quality treated greywater for toilet flushing, laundry, garden irrigation, hand washing and, shower/bathtub use, but not for drinking. When the quality of appearance in terms of colour and odour gets worse, monetary incentives could be needed even for those uses that do not involve human contact. Gender, age, educational level, water expenditure level, and in particular previous knowledge about greywater reuse, are important determinants of acceptability and thus willingness to pay for greywater use; however, their importance varies according to the type of use. Our results provide important insights for understanding the conditions that would precipitate rapid and wide uptake of greywater reuse in cities, and thereby make better use of limited water resources.
