How to Model CULTEC Stormwater Chambers in HydroCAD

CULTEC & HydroCAD Software Solutions Offer a Free Webinar on October 12

BROOKFIELD, CT/August 23, 2010 - CULTEC, Inc. and HydroCAD Software Solutions, LLC will present a free webinar on how to model CULTEC stormwater chambers in HydroCAD® on Tuesday, October 12, from 1-2 p.m. EDT.

Peter Smart, developer and CEO at HydroCAD Software Solutions, and Fred Dotson, Vice President at CULTEC, will discuss the benefits of CULTEC underground stormwater chambers, common applications for these systems, design details, operational analysis of CULTEC systems in HydroCAD, and recommendations for setting up a HydroCAD model.

Specifically, industry professionals will learn how to:

  • Generate a complete inflow or runoff hydrograph to route it through a pond.

  • Calculate water levels attained throughout a rainfall event and any discharge that may occur through outlet devices or infiltration into the surrounding ground.

  • Model complex storage arrangements, such as combinations of multiple chambers, pipe storage and catch basins.

  • Calculate the combined storage for chambers entrenched in a bed of crushed stone at any water surface elevation.

  • Learn additional tips and tricks to get the most out of the HydroCAD model.

    Stormwater industry professionals can register by going to or by calling HydroCAD Software Solutions at 800-927-7246. For further information, please visit

    About CULTEC

    In 1986, CULTEC introduced its Contactor® and Recharger® HDPE septic and stormwater chambers and helped begin a revolution toward the use of plastic construction products. Since then, several product developments and strategic alliances have made CULTEC a cutting-edge R&D-based manufacturer. CULTEC chambers can be used as subsurface retention or detention systems and as replacements for ponds, concrete structures or pipe and stone installations.

    CULTEC manufactures nine different chamber sizes ranging from 8.5" - 32" to accommodate almost any site parameter. The chambers' perforated sidewalls and fully open bottoms promote maximum infiltration capability and allow for the transfer of high volumes of water at a low velocity. The units can be installed singularly or in series in single- or multi-layer beds.

    In addition, CULTEC developed its own in-line side portal manifold system, which eliminates the need for a conventional pipe header system, and water quality unit for maintaining CULTEC chamber systems. CULTEC products meet H-25 wheel load requirements, have a 10-year warranty and are currently modeled in HydroCAD®, Bentley Systems, Inc.'s PondPack®, BOSS International's StormNET®, and Streamline Technologies' ICPR®.

    CULTEC's technical staff offers free design assistance including preliminary calculations and job-specific CAD details. A free CULTEC StormGenie(TM) -- AutoCAD® Plug-In for designing CULTEC systems and a free HydroCAD CULTEC custom edition are also available from the company. In addition, CULTEC products can contribute to the U.S. Green Building Council's credits, under the LEED rating system, when the project is designed per LEED requirements.
