Regulation now requires an alternative rainwater management disconnected from the sewerage systems aiming at
a ZERO DISCHARGE rainwater drainage by the parcel
RAINWATER MANAGEMENT
Climate changes, water imbalance and pollution bring water back at the centre of resources to be protected.
The increasing urban development and its side effect, the waterproofing of soils, impede the natural infiltration of rainwaters. On storm rains, clogged sewers overflow, water treatment plants clog and water suddenly rises in rivers.
The closer to its source rainwater is taken into account, the better it can be managed and valued. Many solutions exist, such as:
-temporary grabbed or roofing storage;
-collection then infiltration into landscaping laying-out;
-storage with or without treatment for further usage
