Excess water drips from the roof gradually so drains are not overwhelmed by a sudden deluge.
Green roof absorb rainwater.
A green roof absorbs rain water by the water buffering in the plants substrate and drainage layer.

Green roofs absorb rainwater grow food.
Green roofs can be effective in both urban and rural areas as a solution to managing rainwater drainage.
Green roofs absorb rainwater and grow food.
Up to 75 of rainfall is absorbed by an extensive living roof and up to 90 is absorbed by an intensive green roof system.
Rainwater is essential for life.
It helps plants and food crops flourish and it keeps grasslands green and lush.
But too much of it especially in the city can lead to flooding causing sewers to overflow and carry pollutants and contaminants to nearby streams and waterways.
This delays the discharge of rainwater to the sewage system purifies the rainwater and water also evaporates through the plants.
Green roof systems are one of the best ways to manage stormwater runoff by reducing and delaying.
