The Contech Design Center provides engineers unparalleled flexibility in the layout and configuration of a detention or infiltration storage system. Our latest release includes options previously unavailable in a free, web-based design tool:

• A 2D/3D design environment with high resolution graphics including BIM model output.
• The ability to import a PDF site plan and design a system to scale over the plan.
• Provide instant access to customized, project-specific drawings.
• Design multiple systems per project and save for future use.
• Digitally collaborate using the new “Project Collaboration” feature. Share your project easily with anyone through the new project management page.

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 and is structurally designed to exceed HS-20/HS-25 live loads in accordance with AASHTO LRFD design specifications for stormwater chambers.
