TWO PROCEEDINGS CAN USE THE STORAGE OF RAINWATER:
- Regulation of rainwater collected from waterproof surfaces. When constructing a building, local regulations increasingly require rainwater to be temporarily stored. This system of retention allows to regulate the heavy precipitation by delaying its evacuation to the storm water network, or to the infiltration zone, in order to avoid the saturation.
- In accordance with the applicable regulations, in particular the decree of August 2008, the rainwater for non-potable uses requires storage.
