i3DLab delivers I/I models for sanitary collection systems using a new technology called inflow and infiltration identification or i3D. The i3D approach results in an antecedent moisture model that is built from data using tools from aerospace engineering, control systems and digital signal processing.

i3D revolutionizes sanitary sewer modeling by giving you a single model that simultaneously matches years of data without having to select capture coefficients or single events to simulate.

The i3D model is simple to execute and the output can easily be imported into SWMM, making long-term continuous simulation easy and fast.
