![]() lateral connections), damaged manhole castings, or leaks from storm pipe trenches near sanitary pipes. Delayed inflow enters the system within a few hours time frame through near-surface damaged pipes (e.g. Inflow ceases within minutes after the storm event. Inflow enters the system in minutes through illicit direct storm pipe connections, foundation drains, downspout connections and displaced or perforated sanitary manhole lids. The splitting approach relies on the distinct difference in the time frame of each RDII stage. ![]() The procedure starts with splitting the three distinct stages of the RDII hydrograph inflow, delayed inflow, and groundwater infiltration, from a flow meter record. This paper presents a step by step procedure for educated continuous calibration of the Rain Dependent Inflow and Infiltration (RDII) using the RTK method in SWMM. ![]()
