The management of water resources in medium and large cities has been changing in recent years, mainly as a result of climate change and the sharp increase of urbanization. In addition to the traditional solution of expansion of water supply, an approach that integrates technological alternatives of demand management in the infrastructure of urban constructions is proposed herein. However, these facilities are often more complex and expensive than conventional ones, being also challenging to achieve a balance between costs and benefits. While the environmental, social, and engineering benefits seem obvious, expressing them in monetary terms is usually a challenge that cost-effectiveness do not respond satisfactorily. Therefore, this research uses the Fuzzy Analytic Hierarchy Process multiple criteria method to rank three main alternatives (rainwater harvesting system, gray water recycling system, and water saving devices) that can be applied in low-income residences in Brazil. For this purpose, this paper considers criteria normally used in this type of analysis such as economic, technical, environmental and social criteria but also includes the local population acceptance and the evaluation of experts. The main results suggest that the most appropriate alternative is the use of water saving devices and that there is also a need for public policies that offer financial incentives to the population and prevent socioeconomic conditions from inhibiting the adoption of water conservation practices.

多标准决策支持,用于选择针对城市综合水管理的替代方案

近年来,由于气候变化和城市化的迅速发展,大中城市的水资源管理发生了变化。除了传统的扩大供水的解决方案外,本文还提出了一种将需求管理的技术替代方案整合到城市建设基础设施中的方法。但是,这些设施通常比传统设施更复杂,更昂贵,在实现成本与收益之间的平衡方面也具有挑战性。尽管在环境,社会和工程方面的好处似乎很明显,但用金钱表示它们通常是一个挑战,即成本效益不能令人满意地做出反应。因此,本研究使用模糊层次分析法的多准则方法对可用于巴西低收入住宅的三种主要替代方案(雨水收集系统,中水回用系统和节水装置)进行排名。为此,本文考虑了通常用于此类分析的标准,例如经济,技术,环境和社会标准,但还包括当地居民的接受程度和专家评估。主要结果表明,最合适的替代方法是使用节水装置,并且还需要制定公共政策,以向民众提供财政激励措施,并防止社会经济状况阻碍采取节水措施。和节水装置),可用于巴西的低收入家庭。为此,本文考虑了通常用于此类分析的标准,例如经济,技术,环境和社会标准,但还包括当地居民的接受程度和专家评估。主要结果表明,最合适的替代方法是使用节水装置,并且还需要制定公共政策,以向民众提供财政激励措施,并防止社会经济状况阻碍采取节水措施。和节水装置),可用于巴西的低收入家庭。为此,本文考虑了通常用于此类分析的标准,例如经济,技术,环境和社会标准,但还包括当地居民的接受程度和专家评估。主要结果表明,最合适的替代方法是使用节水装置,并且还需要制定公共政策,以向民众提供财政激励措施,并防止社会经济状况阻碍采取节水措施。环境和社会标准,还包括当地居民的接受程度和专家评估。主要结果表明,最合适的替代方法是使用节水装置,并且还需要制定公共政策,以向民众提供财政激励措施,并防止社会经济状况阻碍采取节水措施。环境和社会标准,还包括当地居民的接受程度和专家评估。主要结果表明,最合适的替代方法是使用节水装置,并且还需要制定公共政策,以向民众提供财政激励措施,并防止社会经济状况阻碍采取节水措施。
