Implementation Experience of CSO Pollution Control Policies and Procedures in the UK

The Cookstown UPM Study demonstrated that it is possible to carry out a study: • to test compliance of urban wastewater upgrading proposals with a wide range of environmental standards at moderate cost; • to undertake such studies using data that are commonly already available, avoiding the need for expensive field data collection exercises; and • to generate reliable and robust results in which it is possible to have a high level of confidence.
