In the winter of 2019 we completed an in-depth independent comparative analysis of traditional downward flow bioretention to the horiztonal flow WetlandMod. The results were impressive, showing bioretention can maintain a greater than 90% Total Suspended Solids (TSS) removal performance at a moderate hydraulic conductivity over an extended sediment load. More impressively, the WetlandMod horizontal flow set up was able to maintain above 90% TSS removal at a higher hydraulic conductivity and handle 50% more water volume, and 35% more sediment load than traditional bioretention.

WetlandMEDIA is an organic free alternative to traditional bioretention media. It offers higher infiltration rates and a sorptive media mix with high ion exchange capacity. This makes it ideal for nutrient removal. WetlandMEDIA also supports robust vegetation and prevents standing water.
The WetlandMod is designed to utilize any type of bioretention mix required to meet local requirements and specifications, including a 5-Inch Per Hour sand compost mix found in most LID manuals.
