The Green city

-Three-quarters of the world’s population lives in cities

-More green in urban areas

-The positive effects of green

-Directly involve landscape architecture in urban planning

-Green is for using -> not just looking


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.

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.
