WetlandMod | Configurations
One of the biggest challenges of the implementation of LID and bioretention/biofiltration systems is the associated space requirements. The large space requirements of traditional bioretention systems can cause design and feasibility issues, increasing the overall cost to comply with local and state stormwater regulations.
The WetlandMod™ marks the first technological breakthrough to address how we comply with these regulations. The goal of the system is to minimize footprint and land costs associated with traditional bioretention/biofiltration systems. This is acheived by utilizing horizontal flow technology and combining it with traditional downward flow, therefore maximizing the surface area for a given footprint.
Designed To Minimize Required BMP Footprint and Maximize Buildable Space
This system is constructed from modular precast concrete structures. The system comes standard with a curbtype pre-treatment structure, including internal bypass. The biofiltration chambers can be made in any length and shape (shown below) to allow for easy integration with parking lot island designs. The system comes in two standard widths, 4 feet (18” minimum media requirement – San Diego County) and 5 feet (24” minimum media requirement – Los Angeles County).
Footprint Reduction Up To 61% Over Traditional Bioretention Systems
(Example: Planter Boxes, Rain Gardens, Biofiltration)
Open Bottom – Infiltration
This configuration is available with an open basin to maximize infiltration and meet “partial infiltration”
requirements in many jurisdictions. A 12” rock base is recommended under the structure to maximize storage
and infiltration capacity.
Cistern – Storage For Reuse
An optional storage vessel under the biofiltration chamber stores water for reuse, including irrigation and grey
water. The Cistern configuration allows for treated runoff to be stored for later use and a removable sump pump
