Photovoltaic, biomass, biogas, geothermal, these green sectors are multiplying and diversifying. Do these sectors work well?
Aquae Environnement equips Carpe Diem tower at la Défense by ensuring the recycling of rainwater from facades and greywater from washbasins.
Aquae Environnement equips the new headquarters of Bouygues TELECOM by ensuring water supply of 350 toilets on 23 levels and the supply of the system of green spaces watering!
Aquae Environnement equips the new stadium of Nice with rainwater recycled from the 30,000 square meter roof to supply sanitary facilities and fire network as well as to water the lawn.
Millions of cubic meters of water are wasted in France, because people have not yet form the habit of recovering rainwater.
Better use of water resources
Water resources
Water resources for professional uses are:
- water from public distribution systems, in general drinking water, sometimes industrial water;
- natural waters, rivers, boreholes, springs;
- often seen as a constraint, rainwater has become an important part of the resource.
Until a relatively recent past, water management was not a priority. Public drinking water systems had a relatively low cost. Used water was considered as a waste, and the evacuation was free of charge. Today the situation is different. Water is not an inexhaustible resource; it must be managed like other goods. Moreover, it has supply and evacuation cost.
The water law published in the Official Journal of December 31, 2006 (2006-1772) has established a tax covering the costs of water collection. Long-time limited, the use of rainwater has been authorized by the decree of August 21, 2008. It specifies the conditions of the use of rainwater recovered from the downstream of inaccessible roofs, in buildings and their outbuildings, as well as the conditions of installation, maintenance and monitoring of the equipment required for the recovery and use.
AQUAE has been preparing since two years ago for its immediate implementation.

Rain water
Cheap water that covers many needs
Properly filtered and well-stored rainwater is sufficient for the majority of needs except for body and food uses. To consume less drinking water is to allow less stress on the water tables whose levels decrease alarmingly.
A fresh water that provides many benefits
Due to its low limestone content, rainwater is naturally soft. Its use reduces the consumption of detergents, removes the use of softeners and thus allows less discard of phosphate and salt-laden water, which is responsible for the deterioration of water quality and the eutrophication in numerous rivers.
Water retention that regulation requires
This retention obligation aims to limit releases that may saturate the networks, which leads to the installation of storage tanks.
Water for wider use
Long-time limited to external uses, the use of rainwater was extended by the decree of August 21, 2008. It specifies the conditions of the use of rainwater recovered from the downstream of inaccessible roofs, in buildings and their outbuildings, as well as the conditions of installation, maintenance and monitoring of the equipment required for the recovery and use.
