CMP Detention and Infiltration - Meet Stormwater Quantity and Runoff Reduction Requirements

Corrugated metal pipe (CMP) is the “go to” material for the majority of detention and infiltration projects. Contech’s CMP detention and infiltration systems and can be sized and shaped to meet site-specific needs. 

• NCSPA service life guidance of 75+ years for certain materials in recommended environments. Please refer to the Corrugated Metal Pipe Detention Design Guide for additional information.
• Various pipe coatings and materials are available to accommodate site-specific needs: Aluminized Steel Type 2 (ALT2), Galvanized, CORLIX® Aluminum, and Polymeric.
• Wide range of gages, corrugations, and shapes, in diameters 12” – 144”.
• Xfiltration joint can be used for infiltration or groundwater recharge applications.
• Custom access risers and manifolds provide direct access for maintenance.
• Outlet control devices can be incorporated within the system, eliminating the need for a separate structure.
• Customizable - a variety of fittings allow CMP to match most layout configurations.
• May be designed for heavy loading and high maximum cover.
• Contributes to LEED points.
• Available locally; quick turnaround time.
• The most economical installed solution.

The Contech Design Center

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.

High Volume Stormwater Storage Applications

Designing, manufacturing and installing high-volume stormwater detention and treatment systems requires expert engineering, planning, and logistical support to manage costs and keep the project on schedule and under budget. When you need a proven, large scale stormwater management system, “Go Big” with Contech.

Hydrocad

Contech CMP Detention Systems can be easily modeled with the Hydrocad stormwater modeling system, allowing simplified analysis of the devices' behavior in a drainage and stormwater management system.  The Hydrocad chamber library includes detailed storage data for each Contech product allowing automatic determination of their unique stage-storage characteristics.. Click here for details.
