Modular Wetlands® Linear - Stormwater Bioretention
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.
How the Modular Wetlands Linear Works
- Stormwater enters the pretreatment chamber where total suspended solids settle, and trash and debris are contained within the chamber. Stormwater then travels through the pre-filter boxes that provide additional treatment.
- As water enters the biofiltration chamber, it fills the void space in the chamber’s perimeter. Horizontal forces push the water inward through the biofiltration media, where nutrients and metals are captured. The water then enters the drainpipe to be discharged.
- The specially designed vertical drainpipe and orifice control plate control the flow of water through the media to a level lower than the media’s capacity, ensuring media effectiveness. The water then enters the horizontal drainpipe to be discharged.
- During peak flows, an internal weir in the side-by-side configuration allows high flows to bypass treatment, eliminating flooding and the need for a separate bypass structure. Bypass is not provided in the end-to-end configuration.
