The Stormwater Blog

Stormwater management is a critical aspect of sustainable urban development, and hydrodynamic separators (HDS) play a vital role in this process. In this blog post, we delve into the intricacies of HDS devices, looking at the different components, each serving a specific purpose in removing and retaining stormwater pollutants while adhering to hydraulic requirements.

As stormwater quality regulations become increasingly stringent, civil engineers are turning to stormwater filtration Best Management Practices (BMPs) to meet the demand for higher pollutant removal efficiency. In this blog post, we will explore the fundamentals of stormwater filtration, focusing on pollutant removal mechanisms, sizing methods, filtration mediums, and the advantages of proprietary systems.

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
