Abstract: In Flanders, most of the drainage systems are combined sewer systems, in which waste water and rainfall runoff are drained together. However, not only rainfall runoff enters these pipes. Also other sources of water have a contribution to the flow, as e.g. infiltration of groundwater in the pipe system, inflows from drains, creeks, etc… These flows of relatively clean water also arrive at the treatment plant where the influent is diluted and the treatment efficiency consequently decreases.
In order to plan actions to reduce these undesired inflows in the drainage system, it is necessary at first instance to quantify these flows. This paper describes a filter methodology to determine the quantities of these undesired inflows from a time series of the total influent based on the recession times of the different subflows.
