Green Roof Rainwater Management

Furthermore it is possible utilise rainwater harvestingof a green roof contrary to claims from other industries.

Green roof rainwater management.

Eco rainwater solution s philosophy is simple. Green roofs the key hydrological mechanism for interception storage and filtration of water. Excess water drips from the roof gradually so drains are not overwhelmed by a sudden deluge. The volume of water that can be harvested is reduced.

Green infrastructure encompasses a variety of water management practices such as vegetated rooftops roadside plantings absorbent gardens and other measures that capture filter and reduce. Up to 75 of rainfall is absorbed by an extensive living roof and up to 90 is absorbed by an intensive green roof system. Green roof bioretention vegetated roofing roof garden rainwater collection and rainwater harvesting and sustainable site development. The use of any technique or approach that reduces the rate and volume of rainwater runoff has the potential to contribute to better management of the overall quality of rainwater.

Collect treat and release or ideally reuse stormwater close as possible to where it falls. By using green roofs as rainwater capture areas the amount of collected water for reuse will be reduced already due to the absorbed amount of water in the system itself. Second the green roof is a dynamic water flow system that has the ability to capture retain and release rainwater. Green roof and contiguous planted areas above grade and directing all roof drainage to a primary raingarden bioswale with significant depth 2 4 on the north side of the building.

One approach that is used more and more frequently in the management of rainwater i e. Referencing the language manage on site the runoff from the developed site using low impact development lid and green infrastructure we considered a series of lid strategies. Green roofs the key hydrological mechanism for interception storage and filtration of water the use of any technique or approach that reduces the rate and volume of rainwater runoff has the potential to contribute to better management of the overall quality of rainwater. Green roof systems are one of the best ways to manage stormwater runoff by reducing and delaying.

In fact it is quite common to harvest water from green roofs in germany and switzerland. However there are two issues. The roof media also supports a plant growth system that transpires and evaporates water back to the atmosphere. Green roofs can be effective in both urban and rural areas as a solution to managing rainwater drainage.
