Cost effective, easy to use, fit and maintain domestic greywater reuse system

在全球范围内，水是一种日益稀缺的资源。需求的增加，再加上糟糕和漏水的基础设施，增加了现有供水的压力。情况预计将变得更糟，公众、工业和农业的用水量预计将在未来10年增加约16%。在水务公司已经计划的供需平衡行动缺乏进一步行动的情况下，在高人口和高气候变化的情况下，英国的供水短缺预计将在本世纪50年代变得更加普遍\[来源：ASC的气候变化风险评估报告，2017\]。特别是：*英格兰西北部、约克郡和亨伯地区预计极易受到供需不足的影响，伦敦和东南部也是如此。然而，英国其他地区也预计会出现赤字，包括南威尔士和苏格兰中部地带。*在全国范围内，英格兰、苏格兰和威尔士到2050年预计每天将出现8亿至30亿升赤字(占总需求的5%至16%)，到2080年将出现14亿至50亿升赤字(占总需求的8%至29%)。需要解决方案来缓解这些问题，有效利用资源是一项关键战略。随着降低用水量的力度越来越大，人们希望通过低流量淋浴和低冲水马桶来重复使用水，而不是通过低流量淋浴和低冲水马桶来定量供水，而不是通过循环使用淋浴和洗澡水来更大程度地减少用水量。为了满足这种确切的市场需求，我们(Cascade Water Products Ltd.)正在开发一种集成的硬水回收系统，名为Aqua-Offs。我们的技术基于收集家庭淋浴和浴缸的灰水，用适当的杀菌剂处理这些水，然后根据需要分配到马桶水箱使用，当安装到城市家庭和商业新建筑时。免费水箱将提供显著的成本节约，并通过减少家庭用水量至少34%为户主带来实实在在的好处，从而使每户家庭的水费平均降低170 GB。它还将通过弹性产品实现可持续用水，并积极推动节水和节能。

Globally, water is an increasingly scarce resource. Increased demand, combined with poor and leaking infrastructure has increased pressure on existing water supply. The situation is expected to get worse, with water consumption by the public, industry and agriculture is anticipated to rise by ~16 % over the next 10 years.In the absence of further actions to those already planned by water companies to balance supply and demand, under a high population and high climate change scenario, UK water supply deficits are projected to become more widespread by the 2050s \[Source: ASC's Climate Change Risk Assesment Report, 2017\].In particular:* The north west of England and the Yorkshire and Humber region are projected to be highly susceptible to supply-demand deficits, as well as London and the south-east. However, deficits are projected in other parts of the UK as well, including areas of south Wales and the central belt of Scotland.* At a national scale, England, Scotland and Wales are projected to be in deficit by 800 million to 3 billion litres per day by 2050 (5--16% of total demand) and by 1.4 billion to 5 billion litres per day by 2080 (8-29% of the total demand).Solutions are needed to alleviate these problems and efficient use of resources is a key strategy. With an increasing drive to reduce water consumption, it is desirable to reuse water rather than ration it through low- flow showers and low- flush toilets that don't meet public expectation when water consumption can be reduced in larger quantities by recycling shower and bath water instead.In response to this exact market need, we (Cascade Water Products Ltd) are developing an integrated 'hard' waste water recycling system 'Aqua-Gratis'. Our technology is based on collecting grey water from showers and baths in a house, treating the water with a suitable biocide and then distributing to toilet cisterns for use as required which when fitted into urban domestic and commercial new builds.Aqua-Gratis will provide significant cost savings and deliver tangible benefits to the householders through reducing household water consumption by at least 34% resulting in lowering water costs by an average of £170/house. It will also achieve sustainable water consumption through resilient product and actively promote water and energy saving.
