Whether you’re working on large-scale development projects or municipal Bio Retention Basins/swales or rejuvenating existing stormwater solutions, our locally sourced bio retention media ensures optimal performance while meeting regulatory standards. With a focus on durability, efficiency, and eco-consciousness, CSG is your trusted supplier for reliable stormwater management solutions.

Overview: Bio Retention Filter Media (BRFM) is a specialized type of filtration material commonly used in stormwater management systems to treat runoff water before it is released into the environment. It serves as a key component in bio-retention systems, which are designed to mimic natural filtration processes by using plants, soil, and other filter media to remove pollutants from stormwater.

Purpose and Function: The primary purpose of Bio Retention Filter Media is to treat stormwater runoff by removing contaminants such as sediments, nutrients (e.g., nitrogen and phosphorus), heavy metals, and other pollutants. This is achieved through a combination of physical filtration, biological uptake by plants, and chemical processes. Typically designed at a depth of 400mm-600mm or as specified by an engineer.

Key Benefits:

1. Pollution Removal: Effectively reduces pollutants from stormwater, including sediment, nutrients, heavy metals, and organic compounds.
2. Improved Water Quality: Helps improve the overall water quality in nearby rivers, lakes, or streams, making it more suitable for aquatic life and reducing eutrophication risks.
3. Sustainable Solution: Bio retention systems are environmentally friendly, using natural processes to treat water rather than relying on chemical additives or energy-intensive methods.
4. Stormwater Management: Helps in controlling the volume and quality of stormwater runoff, preventing flooding and reducing the burden on municipal water treatment systems.
5. Erosion Control: The vegetation in bio-retention areas can help stabilize the soil and prevent erosion, improving land stability.

Components of Bio Ultra Filter Media:

Bio Ultra is a specifically blended mix of sandy loams and organic matter which is designed to ensure the balance of filtration and retention. The organic matter plays a crucial part in nutrient removal and provides a habitat for microbes that help degrade contaminants.

Our locally sourced Bio Ultra meets the FAWB (Facility for Advancing Water Biofiltration) requirements as well as Water By Design Guidelines (WSUD) & Healthy Waterways.

Applications:

• Urban Stormwater Management: Bio retention systems are commonly used in urban areas to manage the runoff from roads, parking lots, and buildings.
• Green Infrastructure Projects: Often used in conjunction with green infrastructure initiatives aimed at enhancing sustainability and promoting environmental stewardship.
• Construction Sites: Used to mitigate pollution runoff during construction or land development projects.

Maintenance: Though bio-retention systems are relatively low-maintenance, they do require periodic checks to ensure that the vegetation remains healthy, the media does not become clogged, and that the system continues to function effectively. Maintenance may include:

• Replenishing organic material.
• Pruning or replacing vegetation.
• Ensuring that the filter media does not become compacted or clogged with debris.

Environmental Impact: By enhancing natural filtration, Bio Retention Filter Media helps to minimize the negative impacts of urban development on water quality, reduces flooding, and promotes biodiversity through the incorporation of plants into the system.

This solution is increasingly being adopted as cities and municipalities seek sustainable, effective ways to manage stormwater and improve environmental outcomes.
