Utilising catchments or raw water infrastructure as the first stage of treatment will support the UK Water industry's transition towards chemical-free water treatment, offsetting the need for operational expenditure and infrastructure investment and the related environmental impacts. This PhD project, led by Newcastle University, in collaboration with UK Water Industry Research (UKWIR) and the University of Sheffield, looks to advance nature-based and physical interventions in catchments as treatment stages to supplement other catchment management approaches within the UK and Ireland. Fieldwork at Newcastle University's two research farms and experiments at the National Green Infrastructure Facility (NGIF) will establish the benefits of soil amendments or specific vegetation in buffer strips to enhance nutrient/pesticide/solids retention, while features such as ditch barriers, ponds, and leaky dams will also be evaluated for their water quality impacts. Sheffield University will contribute expertise and equipment to characterise the hydrological performance (e.g. pollutant attenuation and retention time) of such features under different flow rates. Newcastle University will deploy its "Lab in a Van" for onsite analysis of chemical and microbial water quality. Taking a holistic view of the catchment system, results from fieldwork, experiments and literature will be used to identify combinations of catchment, water body and raw water infrastructure interventions which realize the full benefits of catchment-based solutions. A decision support tool will be co-developed with water industry and land management stakeholders to define climate change resilient catchment-based treatment solutions and maintenance regimes that protect biodiversity, enhance the public amenity value of catchments and improve the quality of drinking water resources.

利用集水区或原水基础设施作为处理的第一阶段将支持英国水务行业向无化学品水处理过渡，抵消运营支出和基础设施投资的需求以及相关的环境影响。该博士项目由纽卡斯尔大学牵头，与英国水工业研究所（UKWIR）和谢菲尔德大学合作，旨在推进集水区的自然和物理干预措施，作为治疗阶段，以补充英国和爱尔兰的其他集水区管理方法。实地考察在纽卡斯尔大学的两个研究农场和实验在国家绿色基础设施（NGIF）将建立土壤改良剂或特定植被的缓冲带，以提高营养/农药/固体保留的好处，而功能，如沟渠障碍，池塘和渗漏的水坝也将评估其水质影响。谢菲尔德大学将提供专门知识和设备，以评估这些特征在不同流速下的水文性能（例如污染物衰减和保留时间）。纽卡斯尔大学将部署其“货车实验室”，对化学和微生物水质进行现场分析。从集水系统的整体角度来看，实地工作，实验和文献的结果将被用来确定集水，水体和原水基础设施干预措施的组合，实现集水为基础的解决方案的全部好处。将与水行业和土地管理利益攸关方共同开发一个决策支持工具，以确定具有气候变化抗御能力的集水处理解决方案和维护制度，保护生物多样性，提高集水的公共舒适价值，并改善饮用水资源的质量。
