Why do we need Storm Water Management? 1. To improve the ground water table. 2. Lower cost for public sewage system. 3. Lower cost for investors. 4. More green in urban areas. 5. Less impact for the nature. 6. Reduce urban heat island effect by evaporation.

Designing with Stormwater Open Gutter drains Stormwater
Storm Water Circulation Paved Surface big Surface runoff Unpaved Surface less Surface runoff
The dimension of the sewage pipes can be reduced, because the quantity of water is much lower and the remaining water run-off is delayed.
Stormwater Infiltration in Landscape
Hollows (Attenuation Areas) ensure steady Infiltration of accumulated water
Runoff from Driveways / Parking areas into Infiltration Hollow (Attenuation Area) serving as an Overflow
