CULTEC Modifies Recharger V8HD, Updates HydroCAD, Stormwater Design Calculator

Customers Need to Update Design Tools to Continue Using Recharger® V8HD

BROOKFIELD, CT - CULTEC has modified its Recharger® V8HD size parameters. The chamber is now 32 inches high and 60 inches wide, with a bare chamber capacity of 8.68 cubic feet per linear foot, and is typically installed 66 inches on center. In connection with the size modifications, CULTEC updated the Recharger V8HD parameters in HydroCAD® and its own CAD detail sheets and Stormwater Design Calculator.

Design professionals who use HydroCAD to model CULTEC chambers need to download the latest version of HydroCAD software updates to continue designing with the Recharger V8HD accurately. Users with an active HydroCAD registration can download the updated version with the following link: To correctly model with the Recharger V8HD, customers need to choose the Recharger V8I HD (Intermediate) to make up the intermediate sections of a row and one of the V8S HD (Starter) and V8E HD (End) for each row in their model.

The new version of CULTEC Stormwater Design Calculator is available at The latest version of Stormwater Design Calculator must be also used with the CULTEC StormGenie(TM) for accurate system sizing.

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.
