CMP Stormwater Detention and Infiltration

CMP Detention and Infiltration

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

Contech’s corrugated metal pipe’s (CMP) stormwater detention and infiltration systems store stormwater exceeding a site’s allowable discharge rate and release it slowly over time. Systems can be sized and shaped to meet site-specific needs, and are available fully or partially perforated. CMP detention and infiltration systems are available in all AASHTO M-36 types, with various coatings to achieve 75-100 year design service life.

CMP Detention and Infiltration Overview

Corrugated metal pipe (CMP) is the “go to” material for the majority of detention and infiltration projects. Contech’s CMP detention and infiltration systems have a proven service life that exceeds 100-years with proper specification that meets all AASHTO and ASTM pipe specifications and can be sized and shaped to meet site-specific needs

  • 100+ year service life.
  • Various pipe coatings and materials are available to accommodate site-specific needs and extend service life: Aluminized Steel Type 2 (ALT2), Galvanized, CORLIX® Aluminum, and Polymeric.
  • Wide range of gages, corrugations, and shapes, in diameters 12” – 144”.
  • Pipe can be fully or partially perforated 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.

Stormwater Detention

CMP DetentionCMP stormwater detention systems store stormwater runoff exceeding a site’s allowable discharge rate and release it slowly over time. Installed below grade, stormwater detention systems maximize land usage and help meet water quantity requirements.

Stormwater Infiltration

CMP InfiltrationPerforated CMP infiltration systems store stormwater runoff in the pipe and surrounding stone during a storm until it can be slowly released into the surrounding native soil. Perforated CMP is often used to meet Low Impact Development requirements.

Bioretention with Perforated CMP

CMP BioretentionMake bioretention practical for sites with marginal soils by installing perforated CMP. Pipe networks can be configured to meet any size facility. Allows you to reduce the footprint and depth of the bioretention cells.

Low profile/Low drop

CMP for low profile applicationsSmall diameter or pipe-arch shaped CMP can maximize vertical storage space. The low, wide pipe-arch design allows for greater storage in a shallow profile than typical round pipe without losing any structural integrity.
