Modeling Infiltration/Inflow Using a Disaggregated Stochastic Process
To design a sanitary sewer or treatment plant the engineer is required to estimate the daily flow and the peak flow expected in the system. To do this, an estimate of the dry weather flow and the wet weather flow is needed. To produce the most reliable estimates, measured data should be used in determining these flow rates. A procedure is developed to stochastically separate and model the components of dry weather flow, wet weather inflow and subsurface/ground-water infiltration using measured flow records of sewer flows and rainfalls in the area. This model can then be used to estimate the inflow and infiltration for a given storm or design frequency (exceedence probability or risk).
