Stormwater quality regulations continue to expand to include treatment criteria for total phosphorus. Phosphorus is now the second-most-regulated pollutant in

We are an industry of abbreviations and acronyms. The terms we use daily can sometimes hold a general or broad meaning in our minds, but the actual definition

Stormwater regulations are calling for an increased level of treatment. Engineers often specify manufactured, media-based filtration systems to meet the most

Phosphorus is the second-most-regulated pollutant in stormwater runoff after total suspended solids. However, engineers and regulators are still learning how to

As we return to work after the Christmas break, we can’t help but look forward to 2023 and what the future holds for stormwater management. We reached out to several Contech associates to get their insight. Here is what they had to say.

Public parks benefit the community by providing places for recreation, gathering, education, and relaxation. Often, they provide benefits in the form of

A few weeks ago, I searched the term “stormwater” on Google News, and what did I see? Nearly a third of the results were articles about stormwater utilities.

Engineers widely use plastic chambers for retention and/or infiltration of stormwater.  These systems are comprised of rows of open bottom arch-shaped chambers

Bioretention has been the principal form of Low-Impact Development (LID) used to slow, treat, retain and infiltrate stormwater runoff, mimicking a site's natural, pre-development hydrology. One aspect of bioretention that has some scientists and regulators concerned is the phenomenon known as nutrient leaching. Nutrient leaching occurs when the bioretention media, which often contains compost, breaks down and releases phosphorus to downstream receiving waters.

It's hard to believe, but it has been almost twenty years since Filterra bioretention was introduced as a high-flow stormwater treatment system. For those that
