Abstract: Thames Water Utilities Limited (TWUL), together with the UK entities OFWAT, DEFRA, the UK Environment Agency and the Greater London Council, have embarked on the project of to improve water quality in the River Thames. In particular, the plan is to improve the quality of the river by examining the impact of storm flows on the receiving waters. To do this, it was decided that a program be undertaken to study the flows in the London sewers and CSOs that had direct impact on the river. Although the project is more concerned with total flow volumes and the characteristic movement of these flows under external influences such as rain events, additional data has come to light. In particular, what was found is a series of sites that behave in a most irregular manner. The hydraulic regime of any given site is far from predictable. In fact, the hydraulics are so complicated, it is hard to see how a standard sewer flow model will be able to accurately predict the reaction of any given site to a series of either external (e.g., rainfall) or internal (e.g., local pumping conditions) influences. The data presented here show that by employing the data in a real-time mode, procedures can be set and implemented for further control and understanding of the sewer system.
