Newton Fund - Software for Optimal Least-Cost Network Design: Decision support tool for greywater reuse networks in Parana state, Brazil.

可持续发展目标6--确保为所有人提供和可持续地管理水和卫生设施--一直是世界许多地区开发减少水浪费的新技术和战略的推动力。然而，巴西在获得清洁水方面仍然存在严重的不平等，500万人得不到安全饮用水，2500万人得不到适当的卫生设施。专家们一致认为，智能地将淋浴、洗脸盆和洗衣房的水重新用于冲厕所和灌溉等非饮用水用途，可以减少高达40%的淡水需求，从而增加供水机会并减少水费。该项目将使用我们先进的基于软件的水再利用网络(WREN)方法，为巴西库里蒂巴市设计和优化水再利用网络。此项目的2个关键产出将为1。)用于水再利用网络社会经济评估的可靠方法和先进软件。2.)针对水回用网络中使用的管道的集成智能监控系统。我们的Wren系统有潜力减少对淡水的需求，鼓励更公平的水价，并降低最终用户的成本。事实上，通过防止浪费/损失处理过的水，公用事业公司可以大大节省水处理的成本。我们与终端用户的接触可以提高他们的环境意识，并促使他们在日常生活中更加节约资源。此外，更便宜的厕所冲洗再利用水将改善体面公共厕所的可及性，改善5000多万巴西人的生活质量。这反过来将对所有人口部分的一般健康和福祉产生积极影响，并为环境带来重大好处。

Sustainable Development Goal 6 – to ensure availability and sustainable management of water and sanitation for all – has been the impetus for development of new technologies and strategies for reduction of water wastage in many parts of the world. However, Brazil still has major inequalities in access to clean water with five million people without access to safe water and 25 million without proper sanitation. Experts agree that the smart reuse of water from showers, wash basins and laundry for non-drinking uses such as toilet-flushing and irrigation can reduce fresh-water requirements by up to 40%, leading to increased access to water and reduced water bills. This project will design and optimize a water-reuse network for Curitiba city in Brazil using our advanced software-based water-reuse network (WReN) methodology. The 2 key outputs from this project will be 1.) A robust methodology and an advanced software for socio-economic assessment of water reuse networks. 2.) An integrated smart monitoring system for pipes used in water reuse networks.Our WReN system has the potential to reduce requirements for fresh water, encourage fairer water pricing and drive down costs for the end-users. Indeed, by preventing the wastage/loss of treated water, utility companies can make significant saving from the cost of water treatment. Our engagement with end users can increase their environmental awareness and prompt them to be more resource-efficient in their daily life. Also, the cheaper reuse water for toilet flushing will improve the accessibility to decent public toilets, improving the quality of life of over 50 million Brazilians. This will in turn impact positively on the general health and wellbeing of all parts of the population as well as providing significant benefits to the environment.
