Autodesk® Storm and Sanitary Analysis is an advanced, powerful, and comprehensive hydrodynamic modeling package available for analyzing and designing urban drainage systems, stormwater sewers, and sanitary sewers. It can handle a variety of complex flow situations such as looped networks, interconnected ponds, and pumps. In addition, Autodesk® Storm and Sanitary Analysis can model all aspects of stormwater quality/quantity and incorporates best management practices (BMPs), including support for all CULTEC, Inc. storage chambers.


Not only is CULTEC is the front runner for new product designs, we are also the first chamber manufacturer to strategically align with the developers of hydrology modeling software to incorporate and support plastic chamber structures. We are constantly striving to make the engineering community’s stormwater design phase as easy as possible for our clients.

The HydroCAD provides direct support for all CULTEC storage chambers. Although HydroCAD is generally used to perform a complete watershed analysis, it can also be used to perform quick storage calculations for any configuration of storage chambers, including the effects of a stone bed of any shape or size.

Free HydroCAD CULTEC Edition Now Available
CULTEC is pleased to offer the special HydroCAD CULTEC Edition to its customers absolutely free of charge. With the CULTEC Edition you can construct basic watershed models of up to 5-nodes, including complete storage, runoff, and routing calculations using CULTEC chambers.

Note: Since the CULTEC Edition will replace any previous HydroCAD installation on your PC, existing HydroCAD users should generally obtain a version update in order to retain all the capabilities of their existing software.

ICPR is a comprehensive stormwater modeling tool listed with the Federal Emergency Management Agency as a Nationally Accepted Hydraulic Model. ICPR includes an interactive utility to calculate stage-area and stage-volume relationships based on manufacturers’ geometric data for various underground stormwater chambers including CULTEC’s full line of chambers. Once the user settles on a design, the appropriate storage characteristics become part of the overall stormwater model for subsequent hydraulic routing analysis.


PondPack is a FEMA approved software program for detention pond design and hydrology modeling. Users can model rainfall and runoff from urban and rural watersheds to design detention and retention facilities, outlet structures, and channels.

PondPack V8i includes support for a Storage Chamber System pond type which makes it easy for designers to model CULTEC stormwater chamber systems. In addition, PondPack V8i ships with CULTEC chamber data built-in so designers can select their preferred chamber type from a library – saving laborious manual data entry.
