Detention &
Infiltration

Terre Arch’s patented, fiber-reinforced design is lightweight, yet incredibly strong. With a load-bearing rating of HS-25, each section can support heavy gross weight trucks and machinery with virtually no cover required, allowing installation equipment direct access to the site during installation, dramatically reducing installation time and labor. Each Terre Arch installs quickly, The TA26 adds 341 CF, and the TA48 adds 638 CF in a matter of minutes.

In states east of the Mississippi, Contech is the exclusive U.S. seller of Terre Arch.

Here are some of the benefits you'll realize with the Terre Arch system:

Precast Systems for Stormwater Detention

Our CON/SPAN, StormTrap, Terre Arch and Terre Box concrete stormwater detention solutions provide the versatility to accommodate any footprint needed. These patented precast structures are engineered to the highest degree – ensuring structural integrity.

Precast Systems for Stormwater Infiltration

Our CON/SPAN, StormTrap and Terre Arch concrete stormwater detention solutions can be installed on strip footings to allow water to percolate into the soil for infiltration applications.

SS Credit 3 – Brownfield Redevelopment, 1 Point

Intent – Rehabilitate damaged sites where development is complicated by environmental contamination and reduce pressure on undeveloped land.

Potential Contribution: Stormwater Detention and Conveyance Products

Contain runoff without leakage into contaminated soils or groundwater
Several options available for watertight conveyance and storage of water

SS Credit 5.1 – Site Development, Protect or Restore Habitat, 1 Point

Intent – Conserve existing natural areas and restore damaged areas to provide habitat and promote biodiversity.

Potential contribution: Stormwater Detention and Infiltration Systems

Store, recharge and infiltrate stormwater belowgrade
Provide additional opportunity for green space

SS Credit 6.1 – Stormwater Quantity Control, 1 Point

Intent – Limit disruption of natural hydrology by reducing impervious cover, increasing on-site infiltration, reducing or eliminating pollution from stormwater runoff and eliminating contaminants.

Potential contribution: CONTECH Detention Systems

Reduce post-development peak discharge rates

WE Credit 1 – Water Efficient Landscaping, 2-4 Points

Intent – Limit or eliminate the use of potable water or other natural surface or subsurface water resources available on or near the project site for landscape irrigation. Reduce by 50% (2 points) or eliminate (4 points).

Potential contribution: CONTECH Detention Systems

Create water efficient landscaping by harvesting rainwater for re-use
Store water belowgrade or above ground using pipe or structures

WE Credit 3 – Water Efficiency, 2-4 Points

Intent – Further increase water efficiency within buildings to reduce the burden on municipal water supply and wastewater systems. Reduce by 30% (2 points), reduce by 35% (3 points) or reduce by 40% (4 points).

Potential contribution: Contech Stormwater Treatment and Detention Systems

Pretreat rainwater for oil applications such as toilet flushing.

MR Credit 4 – Recycled Content, 1-2 Points

Intent – Increase the demand for building products that incorporate recycled content materials. The sum of post-consumer recycled content plus one-half of the pre-consumer content constitutes at least 10% (1 point) or 20% (2 points), based on cost, of the total value of the materials in the project.

Potential Contributions: Contech Concrete Structures

Many Contech vendors use recycled materials in their concrete mixes
Contact your local Contech representative for project specific information.

MR Credit 5.1 – Regional Materials, 1-2 Points

Intent – Increase demand for building materials and products that are extracted and manufactured locally to a job site in hopes to reduce the environmental impact that would result from transporting these goods. Products manufactured, extracted and recycled within 500 miles of the project site for a minimum of 10% (1 point) or 20% (2 points), based on cost of the total materials value.
