As a water management technique to maintain the ecological and biological characteristics of watersheds and restore rainwater circulation,
it is an industry that is attracting global attention in terms of reducing ecosystem disturbance and enabling soundness of water and heat circulation through rainwater infiltration and evaporation.
| 1. Tree box filter | A facility that reduces pollutants contained in rainfall runoff by reclaiming boxes planted with trees or shrubs and adsorbing oil and phosphorus in the front-end filtration tank and absorbing nutrients and heavy metals by moist soil in the planting part. |
|---|---|
| 2. Plant cultivation bed | A facility that uses spaces such as urban green spaces or flower beds to infiltrate and store rainwater during rainfall, and to reduce non-point pollutants on roads through filtering tanks and moistening work. |
| 3. Unmanaged rooftop greening | A new, no-management roof greening system with increased insulation and soundproofing effects due to zero soil, inducing natural death of weeds by creating a simple and ultra-thin planting base on the roof. |
| 4. Rain Garden | A technological element that effectively manages rainwater and improves the urban landscape by trapping rainwater as much as possible in the ground, collecting and storing rainwater runoff and allowing it to permeate |
| 5. Infiltration Ditch & Vegetation Waterway | In the form of an open shallow trench, it is classified into infiltration trenches and vegetative waterways depending on the presence of vegetation. |
| 6. Modular penetrant | Technological factor for cultivating groundwater and reducing rainfall runoff through underground penetration of rainwater by embedding a modular infiltration tank around trees or shrubs |
| 7. Penetrating packaging | A technical element of the function of reducing rainwater into the soil by penetrating rainwater through the porous sand (porous sand) |
| 8. Sand filtration | A technical element to improve water quality by removing contaminants and suspended substances in the runoff through sand filtration (porous sand) of rain runoff from impervious surfaces |
