Protecting the aquatic environment from urban runoff pollution (StopUP)

通过成功实施城市废水处理基础设施，在保护欧洲淡水方面取得了重大进展，但巨大的压力仍然对接收水体的质量构成威胁。最近对《城市废水处理指令》的评估强调，特别是雨水溢流，包括城市地表径流和合流下水道溢流，将相关污染物负荷带入水生环境。由于全球气候变化的影响，降水更加频繁，干旱情况更加严重，预计这类排放对水资源的压力将会加剧。为了应对这些挑战，需要采取新的办法，有效减轻城市径流和下水道溢流造成的污染，以最终用户和社会负担得起和接受的方式有效减少负荷。StopUP项目将阐明城市集水区的污染途径，以便通过源头、保留和处理措施进行有针对性的干预。它将促进有关排放的知识，包括。通过先进的监测概念、在线传感器以及数据处理和分析，监测污染物的排放、迁移和接收水体。在不同的案例研究中，将进一步开发和测试预防污染的创新技术，例如用于混合下水道溢流处理的高级截留土壤过滤器，这些技术可以更好地融入城市地区。这些测试将展示综合解决方案，包括在地理、气候和水文以及社会经济环境等不同背景下监测、处理和控制扩散性污染。根据调查结果，将得出支持最终用户（包括环境当局、水务局/公用事业公司、咨询公司）选择、实施和操作污染物缓解措施的工具。

Major progress has been achieved in protecting European freshwaters through the successful implementation of urban wastewater treatment infrastructures but significant pressures still pose threats to the quality of the receiving water bodies. The recent evaluation of the Urban Wastewater Treatment Directive underlined that, in particular stormwater overflows including urban surface run-off and combined sewer overflows bring relevant pollutant loads into the aquatic environment. The pressure on water resources from those kinds of emissions is expected to aggravate through the impacts of global climate change with more frequent intense precipitation as well as more pronounced drought conditions. To address those challenges new ways in effectively mitigating pollution arising from urban run-off and sewer overflows are needed, providing effective load reduction, in a way affordable as well as acceptable to end users and the society. The StopUP project will elucidate pollution pathways in urban catchments to enable targeted interventions through measures at source, retention and treatment. It will foster knowledge about emissions incl. pollutant release, transport and receiving water bodies through advanced monitoring concepts, online sensors and data processing and analysis. In the context of different case studies, innovative technologies for pollution prevention such as advanced retention soil filters for combined sewer overflow treatment which can be integrated better in urban areas will be further developed and tested. The tests will demonstrate integrated solutions including monitoring, treatment and control of diffusive pollution in different contexts concerning geographic, climatic and hydrological as well as socio-economic settings. Based on the findings, tools to support selection, implementation and operation of pollutant mitigation measures for end-users including environmental authorities, water boards/utilities, consultancies will be derived.
