CULTEC Chambers supported by HydroCAD

CULTEC products are fully supported by the HydroCAD Stormwater Modeling System, making it easy to  design and model underground retention and detention facilities that employ CULTEC chambers.

CULTEC and HydroCAD formed their alliance back in 2003. Up until that time, the software program had never modeled chambers or a specific proprietary product --this is just one example that shows how CULTEC strives to think up new developments and relationships to make the design phase as painless as possible.

New Chamber Definition for HydroCAD Available
June 22, 2010 - There is a new chamber update available for the Recharger V8HD for HydroCAD. The chamber is 32" high, 60" wide and typically installed 66" on center. Chamber storage is 8.68 cubic feet per foot.

To get the latest HydroCAD updates click here and choose the version you currently have from the list at the bottom of the page.

Already own HydroCAD?

The latest HydroCAD-9 release includes all current CULTEC chamber definitions, plus a new chamber wizard which greatly simplifies the layout, pricing, and modeling of underground storage systems.  Users of earlier versions can update at very reasonable rates.

Not using HydroCAD?

CULTEC is pleased to offer the special HydroCAD CULTEC Edition to it's 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.

Free for Limited Time Only:

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.

In a HydroCAD model, stormwater chambers typically appear as part of the storage definition for a "pond".  In the simplest case, HydroCAD calculates the available storage for use with other calculations.  But more often, it is used to generate a complete inflow or runoff hydrograph and route it through the pond.  The resulting analysis indicates the water levels attained throughout the rainfall event, as well as any discharge that may occur through outlet devices or infiltration into the surrounding ground.

Flexible storage options

Each pond may include an unlimited number of storage definitions as required to describe its overall storage characteristics.  This makes it easy to model complex storage arrangements, such as a combination of multiple chambers, pipe storage, catch basins, or other contributing volumes.

But the most significant feature is the ability embed (bury) chambers in a bed of crushed stone, and have HydroCAD automatically calculate the combined storage at any water surface elevation.  This makes it easy to determine the storage for virtually any configuration of storage chambers, without resorting to any manual calculations.  And the underground storage wizard in HydroCAD-9 takes this a step further, by performing automatic layout of the infiltration bed using the recommended bedding, spacing, and cover for each chamber model.

HydroCAD can also model more complex storage arrangements, such as layered chambers, auxiliary storage from pipes and catch basins, and even the above-ground areas (parking lot) that may provide overflow storage for larger events.

Setting up a pond to use CULTEC storage chambers is a simple process:  Just pick the desired model(s) from the drop-down list, and specify the number of chambers plus their elevation.  HydroCAD supports all CULTEC, Inc. chambers, including all Recharger, Contactor, HVLV, and Field Drain models.

For embedded storage calculations, the underground storage wizard automatically creates the associated drainage field based on the specified layout parameters.  Using the built-in chamber definitions and stone voids, a complete stage-storage curve is instantly available for reporting or further analysis.
