BIO RETENTION SYSTEMS

TREE POD BIO FILTER SYSTEM:    

BioMod Modular Bio-retention System is a modular precast concrete biofiltration cell system that has been developed to add consistency to design and construction, with features to enhance filter performance, structural integrity and reduced construction and ongoing maintenance costs.

The Silva Cell is a modular suspended pavement system that uses soil volumes to support large tree growth and provide powerful on-site stormwater management through absorption, evapotranspiration, and interception.
 

What is a Bio Retention?

Definition a bio-retention system consists of a soil bed planted with suitable non-invasive (preferably native) vegetation.

Stormwater runoff entering the bio-retention system is filtered through the soil planting bed before being either conveyed downstream by an underdrain system or infiltrated into the existing subsoil below the soil bed.

Vegetation in the soil planting bed provides uptake of pollutants and runoff and helps maintain the pores and associated infiltration rates of the soil in the bed. 

A bio-retention system can be configured as either a bio-retention basin or a longer, narrower bio-retention swale. In general, a bio-retention basin has a flat bottom while a bio-retention swale may have sloping bottom. Runoff storage depths above the soil bed surface are typically shallow.

The TSS removal rate for bio-retention systems is 80 or 90 percent, depending upon the thickness of the soil planting bed and the type of vegetation grown in the bed. 

Purpose Bio-retention systems are used to remove a wide range of pollutants, such as suspended solids, nutrients, metals, hydrocarbons, and bacteria from stormwater runoff. They can also be used to reduce peak runoff rates and increase stormwater infiltration when designed as a multi-stage, multi-function facility.
