This technical note if for Modeling StormTech Chambers in HydroCAD. It provides information about modeling requirements for chambers as a pond. The steps are outlined.

StormTech chambers are modeled in HydroCAD either using the Chamber Wizard or entered manually. We recommend modeling them manually for the best accuracy. When manually modeling, the StormTech chambers are placed or “embedded” in a stone envelope. The first step when modeling the chambers is to enter the dimensions of the stone envelope. The stone envelope includes the one foot (min.) stone perimeter around the chambers and the excavation volume around the manifold (if the manifold volume is to be included in the total storage volume).

There are 22 steps to guide the modeling process from opening the HydoCAD and creating a new project to summary of the overall system when complete.
