Storm‐sewage overflows are one of the principal sources of urban river pollution in the UK. The paper (a) outlines the various possible pollutants and their effect on the receiving stream, and (b) identifies the features of individual overflow structures which are likely to lead to unsatisfactory performance. Since the rationalization and rehabilitation of storm‐sewage overflows should only be considered as part of a more general drainage area study, a strategy for rationalization is presented which identifies objectives for effective design and operation; it discusses, in particular, how chambers may be proportioned to give effective separation of visible pollutants. By combining field data with the results of model tests, a comparison of the performance of the main recommended types of overflow structure is given, together with a discussion of maintenance and safety aspects.
