Green roof irrigation requirement.

Planning for irrigation on a green roof should consider the site layout and conditions access exposure type of plants climate and water supply issues pressure quality etc. Substrate properties and depth are also important as they influence water infiltration holding capacity and drainage. For extensive green roofs that require occasional watering. Irrigation system to be sized correctly for all projects.

We suggest on an extensive sedum green roofs a permanent irrigation system is not necessary but consideration must be paid to the roof and supplementary watering if periods of prolonged drought 2 weeks occur. Optimizes distribution of rain irrigation water across the roof surface even on steeply pitched roofs. A truly environmentally friendly solution. The deeper the substrate used the more moisture it can hold to ensure plant survival during dry periods.

For green roofs that receive runoff from roof directly connected impervious area dcia inlet control systems may convey and control the flow of stormwater from the contributing catchment area to the green roof. Irrigation is a key component to a successful project. Enables the vegetal i d.
