DEVICE CONNECTED TO DOWNWATER RAINFALL FROM ROOF TO STORAGE EXCEPTIONAL RAIN

摘要

Device comprising a large volume of sealed storage placed on the ground to store the exceptional rain from the downflows of rainwater roofs via a sealed pipe for its filling by the principle of communicating vessels. This device is mainly a planter composed of a decorative tray, a planted substrate and a reserve of large volume water placed under the substrate. This planter can be positioned where you want on the ground, near or remote from the connected roofs. It is mainly used for the management of exceptional rainwater with regard to saturation of sanitation networks and floods as well as the reduction of the impact of all rains with respect to pollution. The collected rainwater is also used to feed the plantations, even in times of drought. The water collected in the reserve is then regularly evacuated by evapotranspiration of the plants. Excess water not taken up by plants can be used for other purposes such as cleaning sidewalks or roads. This device, intended mainly for highly urbanized areas, makes it possible to manage the exceptional rainfall easily and economically without resorting to expensive underground storage devices. It is economical because it is multifunctional and can bring greenery, freshness and biodiversity in very mineralized cities. It is fully in line with climate change, where temperatures are rising and exceptional rainfall is increasing.
