Some media-based stormwater filtration system manufacturers offer different types of media, allowing engineers to design systems for site-specific pollutant removal.

Phosphorus is the second-most-regulated pollutant in stormwater runoff after total suspended solids. However, engineers and regulators are still learning how to remove phosphorus from stormwater to promote healthy waterways and meet agency requirements.

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.

It’s that time of year again - temperatures have dropped below freezing, and the wintery weather has blown in. Departments of Transportation, state, local and city road crews are being kept on their toes, applying roadway treatments and safe passage for all of us. It is estimated that the US spends approximately $2.3 billion annually to keep highways free of snow and ice, and roughly 20% of transportation department budgets goes toward winter road maintenance.

We’ve all heard the expression “can’t see the forest for the trees,” but when’s the last time you can remember it applying to yourself? As a stormwater

This month’s blog post comes from Janice Kaspersen, editor of Stormwater magazine. Did you drive to work this morning? Was a parking space waiting for you when

We all know that stormwater runoff carries trash and debris into our water ways, but have you ever wondered what kind of material this runoff picks up? A Contech Continuous Deflective Separation unit (CDS) was installed on a site in California and the performance of the unit was monitored over a 12 months. During a maintenance event, the trash and debris that was captured by the CDS was removed, and the contents were separated and characterized.
