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.

在全球范围内，水是一种日益稀缺的资源。需求增加，加上基础设施差和漏水，增加了对现有供水的压力。预计情况将变得更糟，公众、工业和农业的用水量预计将在未来10年内增加约16%。如果自来水公司没有采取进一步行动来平衡供需，在高人口和高气候变化的情况下，预计到2050年代，英国供水短缺将变得更加普遍。ASC的气候变化风险评估报告，2017年。特别是：* 英格兰西北部和约克郡和亨伯地区预计将非常容易受到供需赤字的影响，以及伦敦和东南部。然而，预计英国其他地区也会出现赤字，包括南威尔士地区和苏格兰中部地区。在全国范围内，预计到2050年，英格兰、苏格兰和威尔士将出现每天8亿至30亿升的赤字（占总需求的5- 16%），到2080年将出现每天14亿至50亿升的赤字（占总需求的8-29%）。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。随着减少水消耗的日益增长的驱动力，当水消耗可以通过回收淋浴和洗澡水来大量减少时，期望通过低流量淋浴和低冲水马桶来再利用水而不是配给水，这不能满足公众的期望。我们（Cascade Water Products Ltd）正在开发一种集成的“硬”废水回收系统“Aqua-Gratis”。我们的技术是基于从房子的淋浴和浴缸收集灰水，使用合适的杀菌剂处理水，然后根据需要分配到厕所水箱中使用，安装在城市住宅和商业新建筑中。Aqua-Gratis将通过减少至少34%的家庭用水量，为住户节省大量成本并带来切实利益这意味着平均每户的水费降低了170英镑。本集团亦将透过具弹性的产品实现可持续用水，并积极推动节水节能。
