The prediction of sewer flow quality in combined sewer systems under storm conditions is becoming increasingly important to the international water industry as there is a need to minimise environmental impact and to meet ever increasingly stringent regulatory requirements. Software to simulate the behaviour of combined sewers under storm conditions is now available and has been successfully applied to a variety of catchments. However, in many cases there are known limitations in the application and use of such models, particularly with respect to the simulation of quality performance. These limitations relate primarily to the complexity of the processes, systems and the time required to investigate the impact of design options. There is therefore scope to develop new, simplified approaches that are able to simulate sewer flow quality at times of storm. Such models are required to reduce computational times, while being efficient and equally as accurate as the conventional models. The development of such a modelling tool is presented in this paper, together with results of preliminary testing undertaken on a 285 ha catchment in the North of England. Results show favourable comparison between measured and simulated data.
