The Modular Wetlands Linear is the only biofiltration system to utilize patented horizontal flow, allowing for a smaller footprint, higher treatment capacity, and design versatility. It is also the only biofiltration system that can routinely be installed downstream of storage for additional volume control and treatment.
With numerous regulatory approvals, the system’s aesthetic appeal and superior pollutant removal make it the ideal solution for a wide range of stormwater applications, including urban development projects, commercial parking lots, residential streets, mixed-use developments, streetscapes, and more.
Features | Benefits |
---|---|
Pretreatment chamber | Enhanced pollutant removal, faster maintenance |
Horizontal flow biofiltration |
Greater filter surface area |
Performance verified by both the WA DOE and NJ DEP |
Superior pollutant capture with confidence |
Built-in high-flow bypass |
Eliminates flooding and the need for a separate bypass structure |
Available in multiple configurations and sizes |
Flexibility to meet site-specific needs |
The Modular Wetlands Linear continues to outperform other treatment methods with superior pollutant removal for TSS, heavy metals, nutrients, and hydrocarbons. The Modular Wetlands® Linear is field-tested on numerous sites across the country and is proven to effectively remove pollutants through a combination of physical, chemical, and biological filtration processes.

The Modular Wetlands Linear has been evaluated by some of the most stringent stormwater technology evaluation organizations in North America, including, but limited to:
Technical information for this product is located in the technical guide’s section.
The Curb Inlet configuration accepts sheet flow through a curb opening and is commonly used along roadways and parking lots. It can be used in sump or flow-by conditions.
The Vault configuration can be used in end-of-the-line installations. Another benefit of the “pipe-in” design is the ability to install the system downstream of underground detention systems to meet water quality volume requirements, or for traffic-rated designs (no plants).
The Downspout configuration is designed to accept a vertical downspout pipe from rooftop and podium areas. Some models have the option of utilizing an internal bypass, simplifying the overall design. The system can be installed as a raised planter, and the exterior can be stuccoed or covered with other finishes to match the look of adjacent buildings.
