ChamberMaxx® Stormwater Chamber System

The ChamberMaxx corrugated, open-bottom plastic infiltration chamber system allows you to meet stormwater runoff reduction requirements and maximize available land space by providing economic infiltration below grade. ChamberMaxx maximizes storage volume in a small footprint, and its low profile shape is ideal for sites with shallow footprints.

Design Your Own Detention or Infiltration System

The Contech DYODS is an exclusive online design tool to that allows users to quickly and easily design a detention or infiltration system. Just input your required storage volume to calculate the quantity of the material needed for your Contech CMP, CON/SPAN, or ChamberMaxx  system. 
Bioretention and Subsurface Infiltration with ChamberMaxx

Given its aesthetic appeal, bioretention is often the first choice for Low Impact Development (LID) and Green Infrastructure (GI) design. ChamberMaxx can help make bioretention practical for sites with limited footprints. The open-bottom plastic chamber allows infiltration into surrounding soil, effectively achieving runoff reduction objectives. ChamberMaxx is ideal when you need to maximize storage capacity in shallow footprint bioretention cells.

ChamberMaxx for Subsurface Infiltration

An open bottom plastic chamber the ChamberMaxx allows infiltration into surrounding soils, effectively achieving runoff reduction objectives often required by in an LID (low impact development) design. Maximize available land for development by installing a belowground system while still significantly reducing the volume of stormwater runoff.

Pretreatment Systems

ChamberMaxx Installation

ChamberMaxx is lightweight and is installed by hand without the need of heavy equipment. ChamberMaxx is available locally, resulting in short lead times; and installation support is provided by Contech.

Maximize Stormwater Storage in Shallow Footprints

The ChamberMaxx corrugated, open-bottom plastic infiltration chamber system allows you to meet stormwater  runoff reduction requirements and maximize available land space by providing  economic infiltration below grade. By utilizing subsurface infiltration, space  is preserved for development or green space, runoff is reduced or eliminated, and  groundwater recharge can occur.

ChamberMaxx maximizes storage volume in a small footprint, and its low profile shape is ideal for sights with shallow footprints. Each chamber provides 47 ft3 (1.3 m3) of storage.

The integrated end caps eliminate the expense associated with loose end caps that are common on many chamber systems and add to chamber strength.

ChamberMaxx is manufactured per ASTM F 2418-05 and is structurally designed to exceed HS-20/HS-25 live loads in accordance with AASHTO LRFD design specifications for stormwater chambers.
