Stormwater Management

Does Contech offer a plastic crate detention system?

No, Contech does not currently offer a plastic crate detention system. Contech has chosen not to manufacture this type of system due to concerns about long-term access, inspection, and maintenance. Underground detention systems collect sediment, trash, and debris over time, so the ability to inspect and clean the system is an important design consideration.

Can Contech guarantee a certain pollutant removal efficiency in their stormwater systems?

Municipal stormwater flow rates and pollutant concentrations are highly variable over the course of a storm, between storms, seasonally, and with changing activity in the contributing watershed.

Which BMP works best when we don’t have much depth?

The best BMP for a shallow site depends on the available rim-to-invert depth, pipe sizes, hydraulic grade line, treatment requirements, and whether the BMP is at-grade or underground.

What equipment is typically required to install Contech stormwater products?

Most Contech products can be installed using standard civil construction equipment such as excavators, loaders, compaction equipment, and, where required, cranes or other lifting equipment. The exact equipment depends on the product type, structure size, site access, and contractor means and methods.

What are the different types of stormwater treatment systems?

Stormwater treatment systems are designed to manage runoff and remove pollutants before water enters storm drains, groundwater, rivers, lakes, or other receiving waters. The right system depends on the project’s drainage area, pollutant targets, regulatory requirements, available footprint, hydraulic conditions, maintenance expectations, and site constraints.
