In this video, Vaikko Allen, Regional Regulatory Manager for CONTECH, explains Lane’s Diagram, illustrating the balance between the erosion of the soil and the flow rate of a body of water.

During the past few years, a number of different filter media have been used for stormwater filtration. Media such as sand, peat, and compost have been used successfully. Recent uses of perlite, zeolite, carbon, and other “exotic” media have expanded the choices for targeting specific pollutants. Here are some questions you should ask when selecting the right media for your application...

A common challenge we are seeing among our customers is an increasing demand for infiltration despite limited site space.

In this video, Cory Carlson, Detention Product Manager for Contech, explains how you can quadruple your storage volume by doubling the diameter of your storage or infiltration pipe, giving you significant savings per cubic foot.

The intent of LEED Sustainable Sites Credit 6.2 is “to limit disruption and pollution of natural water flows by managing stormwater runoff,” and the requirements necessary for meeting this intent are clearly spelled out: capture 90% of the average annual rainfall and treat it by removing 80% of the total suspended solids (TSS). While the rating system does not define TSS it does recommend reliance on field monitoring data that is compliant with the Technology Acceptance Reciprocity Partnership (TARP) protocol or the Technology Acceptance Protocol-Ecology (TAPE) when screening stormwater best management practices (BMPs). Seemingly straightforward, but...

In this video, Vaikko Allen, Regional Regulatory Manager for CONTECH, explains three approaches to stormwater treatment.

By now, you’ve probably heard of triple bottom line accounting, a full cost accounting approach considering the economic, environmental and social impacts of a decision or more poetically, the three P’s: people, planet and profit. In the stormwater infrastructure planning world, as in many other urban planning arenas, this approach is gaining popularity.

This short video explains how rainwater harvesting is a logical and feasible approach to managing stormwater runoff using example usage for a typical commercial office building.

The primary credit applicable for the Stormwater Management StormFilter^® is Credit 6.2, Stormwater Design - Quality Control, under the Sustainable Sites category. There is one credit point allowable under this category for qualifying BMPs.

This patented technology is employed by the Stormwater Management StormFilter in order to prevent surface blinding, ensure use of all media, and prolong cartridge life. In principal, the system siphons stormwater runoff through its cartridge.

As an industry, we’ve acquired a vast amount of knowledge about stormwater, its adverse impacts and the best management practices (BMPs) implemented to mitigate them. However, the spirited debate with regard to whether the field or the laboratory is the best arena for evaluating BMP performance refuses to yield to consensus. Here are some of the arguments for and against laboratory testing...
