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——确保人人享有水和卫生设施并对其进行可持续管理——一直是世界许多地区开发新技术和减少水浪费战略的动力。然而，巴西在获得清洁水方面仍然存在严重的不平等现象，500万人无法获得安全用水，2500万人没有适当的卫生设施。专家们一致认为，将淋浴、洗脸盆和洗衣房的水巧妙地重新用于如厕和灌溉等非饮用用途，可将淡水需求减少多达40%，从而增加用水并减少水费。该项目将采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。这个项目的2个关键产出将是1。对水再利用网络进行社会经济评估的可靠方法和先进软件。2.） 用于水回用网络的管道集成智能监控系统。我们的WReN系统有可能减少对淡水的需求，鼓励更公平的水价，并降低最终用户的成本。事实上，通过防止处理过的水的浪费/损失，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，有助提高他们的环保意识，并促使他们在日常生活中更节约资源。此外，更便宜的厕所冲洗再利用水将改善使用体面公共厕所的机会，提高5000多万巴西人的生活质量。这反过来将对所有人口的总体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.
