UNDERGROUND BIORETENTION

A bioretention cell is designed to treat polluted stormwater runoff  from adjacent pavement. TreeParker bioretention system uses the rootsoil volume and does not take up extra space like ordinary bioretention systems.

CIRCULAR URBAN WATERCYCLE

Urbanization is characterized by a high percentage of impervious surfaces and limited green areas, and has altered the natural water balance leading to a much greater discharge of waste water and poor quality runoff. Infiltration into ground water is reduced and quality may also be degraded due to the presence of pollutants, which in turn damage aquatic habitats. Limited tree cover reduces water storage in root systems, the release of water into the atmosphere through transpiration, and natural pollution filtering through tree roots especially.
As a consequence, increased attention is being paid to managing the water cycle in urban development. Often referred to as Water Sensitive Urban Design (WSUD) or Sustainable Drainage Systems (SuDS). These are an alternative approach to traditional stormwater management. It tries to compensate for the effects of excessive paved areas and to limit the changes in natural water management by local water reuse and temporary storage. The main principles include the integration of rainwater treatment in the landscape, the protection of its quality and the reduction of peak loads caused by the more extreme rain events.

WSUD 

Water sensitive urban design (WSUD) uses better urban planning and design to reuse stormwater, stopping it from reaching our waterways by mimicking the natural water cycle as closely as possible. Known practices are:
Raingardens are specially-designed garden beds that filter stormwater runoff from surrounding areas. Raingardens are also called bioretention systems because they use soil, plants and microbes to biologically treat stormwater.
+ Bioretention; polluted water is purified
- Needs a lot of surface.
Water infiltration units are designed structural units for submerged use. And manages two important tasks: subsurface water retention and infiltration. The units combines high storage capacity with an enormous stability for underground use.
+ No extra surface needed, installation underneath pavement
- Polluted water infiltrates groundwatersystem

Typical bioretention versus underground bioretention

TREEPARKER UNDERGROUND BIORETENTION

TreeParker underground bioretention system serves both functions; bioretention and underground water storage. A "submerged raingarden" existing of modular units that uses soil to support large tree growth and providing powerful on-site stormwater management through absorption, evapotranspiration, interception and filtration. And not taking up extra space in the crowded cityscape.
