New Environment Agency report on 'Understanding the performance of water supply systems during mild to extreme droughts'

Current water resources planning in England and Wales tests the resilience of public water supply systems against the worst historical droughts in the observed record. This approach, however, does not assess how a water supply system would respond when pushed beyond these historical design conditions. This project aimed to understand the performance of different types of water supply systems to a range of droughts, including those that are more severe than the worst case historical droughts,
