Climate-resilient management for safe disinfected and non-disinfected water supply systems

在气候变化的压力下，安全和负担得起的饮用水供应（DW）是欧盟的关键优先事项。尽管在消毒和非消毒饮用水供应系统（DWSS）的可靠运行方面有长期经验，但围绕微生物稳定性、（未来）消毒需求以及消毒副产物（DBPs）形成对人类健康的影响等方面的一些挑战仍然存在，这些挑战直接源于气候变化影响，如水温升高和天然有机物（NOM）水平升高。Safe CREW旨在通过为消毒和非消毒DWSS提供先进的知识和开发工具和指南来支持新的欧盟DW指令，并解决改进的全面水质表征，新的处理解决方案，以积极响应已确定的威胁，以及分配网络的管理，以避免水质恶化到消费者。将创建关于迄今未知DBP的发生和浓度的新数据集，并鼓励商业行为者进一步开发DBP量化和缓解工具。将向最终用户（水务公司、国家/欧盟监管机构、研究人员、中小企业）提供可转让的工具，包括：(I)评估微生物稳定性、表征NOM、检测DBP和解释DBP对人体健康的毒性的可靠方法；（II）选择与消毒水接触的适当材料的协议；（III）监测和建模工具，也利用机器学习，实时优化DWSS管理；（四）建立一个综合风险评估框架，指导今后的干预措施，确保已消毒和未消毒的水卫工都能在气候变化的情况下继续提供安全的水卫工。Safe CREW将增强欧盟水务部门应对气候变化挑战的准备，并将支持欧盟在基于科学的DW消费者保护政策制定方面的领先地位。

Safe and affordable supply of drinking water (DW) in the EU under the pressure of climate change is a key priority. Despite long-term experience with the reliable operation of disinfected and non-disinfected drinking water supply systems (DWSS), several challenges around microbial stability, the (future) need for disinfection and the consequences of disinfection by-products (DBPs) formation for human health remain open, directly deriving from climate change impacts such as increasing water temperature and higher levels of natural organic matter (NOM). Safe CREW aims to support the novel EU DW Directive by generating advanced knowledge and developing tools and guidelines for disinfected and non-disinfected DWSS and addresses improved comprehensive water quality characterization, novel treatment solutions to actively respond to identified threats, and the management of distribution networks to avoid water quality deterioration up to consumers. Novel data sets on the occurrence and concentration of so far unknown DBPs will be created, and commercial actors stimulated to further develop tools for DBP quantification and mitigation. Transferable tools will be provided to end-users (water utilities, national/EU regulators, researchers, SMEs), including: (I) reliable methods to evaluate microbial stability, characterise NOM, detect DBPs and account for DBP human health toxicity, (II) protocols to select proper materials in contact with disinfected water, (III) monitoring and modelling tools, also exploiting machine learning, for real-time optimisation of DWSS management, and (IV) an integrated risk assessment framework to guide future interventions which ensure that both disinfected and non-disinfected DWSS can continue providing safe DW in the face of climate change. Safe CREW will increase the preparedness of the EU water sector to challenges arising from climate change and will support the EU’s leading position in science-based policy making for DW consumer protection.
