Civil engineers understand the delicate balance between form and function. High-rate bioretention systems, known for their efficiency in managing stormwater, offer an often overlooked benefit: aesthetics. Integrating visually appealing bioretention systems into urban landscapes can enhance community engagement, foster sustainability, and improve the overall perception of civil infrastructure.

Hydrodynamic Separators (HDS) have been a staple in stormwater management for over twenty years. Choosing the right HDS unit for your project can be challenging, but understanding key design considerations can help guide you through the process. This blog post reviews several important factors to consider when sizing your HDS unit.

Hydrodynamic separators (HDS) are increasingly recognized as essential components in modern stormwater management systems. These devices effectively remove pollutants from stormwater runoff, helping to protect water quality and meet regulatory requirements. However, the successful implementation of HDS requires careful consideration of various design factors. This article outlines best practices for engineers to ensure the effective performance and longevity of hydrodynamic separators.

In stormwater management, manufactured treatment devices (MTDs) are often recognized as innovative solutions for controlling runoff and enhancing water quality. Yet, despite their growing adoption, several misconceptions about these devices persist, leading to confusion and misinformed decisions. This blog will tackle some of the most prevalent myths surrounding MTDs, shedding light on their true capabilities and effectiveness.

Proprietary stormwater treatment systems, or stormwater control measures (SCMs), offer several unique benefits compared to traditional land-based SCMs. Perhaps best known for their space-efficient design, making them well-suited and essential tools when managing stormwater runoff in ultra-urban environments, proprietary SCMs have several additional benefits discussed in this blog post.

Hydrodynamic separators are primarily designed to treat stormwater runoff by removing pollutants such as sediment, debris, oil, and grease. But what happens when tailwater conditions obstruct the flow?

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.
