Check out our brand new CULTEC StormGenie™ Automated Drawing Program.

The CULTEC StormGenie™ is an AutoCAD® plug-in for designing CULTEC Stormwater Systems. It is used in conjunction with CULTEC's Stormwater Design Calculator to generate project-specific AutoCAD® drawings for CULTEC's Contactor® and Recharger® Retention and Detention Stormwater Systems. The StormGenie™ takes information from the Stormwater Design Calculator and creates square beds based on the client's project input.

No other stormwater product manufacturer has a drawing program like this!
Just another way that CULTEC is making the design phase that much easier.

Benefits of CULTEC StormGenie™
Excellent for creating preliminary system proposals to clients without spending a lot of time
Quick way to draw accurate bed layouts that can be modified into irregular sized beds
Great for contractors and landscape architects to draw systems for review by an engineer or client
Ideal for professional looking drawings for bids, conceptual systems or product substitutions

HOW TO SUBMIT INFORMATION FOR DESIGN ASSISTANCE

CULTEC’s Technical Department can assist you with the design of your CULTEC Stormwater System by aiding with preliminary calculations, shop drawings and submittal packages.

Our Technical Staff is able to convert plans from existing pipe and stone systems, ponds, concrete structures and competitor chamber products to propose an equivalently sized septic or stormwater system utilizing CULTEC products.

We provide system layouts, cross section details and other CAD details for you to pick and plot for use on your blueprints.

Please note that CULTEC is able to provide these services free of charge and is limited to proposals and evaluating that the criteria meets minimum CULTEC requirements. It is the client’s responsibility to have all work reviewed and approved by a licensed professional engineer.

HydroCAD CULTEC
 Custom Edition
Now Available!

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 latest HydroCAD-9 release 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 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.

>>Click here to download the CULTEC Edition and select the "Run" option.

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 beome part of the overall stormwater model for subsequent hydraulic routing analysis.
