Sustainable Development

Attractiveness :

The infrastructure of the Vitry-sur-Seine flood pumping station was designed and implemented in a global approach to sustainable development. The structure responds to a common problem that many cities experience: the impermeability of soils and the bad flow of rivers. The construction of this equipment is part of a global approach to overcome these issues. Sustainable development was conceived both at the design stage of the project, with the use of recyclable materials, the establishment of a green roof to bring biodiversity, and at the site stage.

The objectives of the project were to have a green building site and a quick project so as not to impede the construction of the nearby SMI line 15 of the Greater Paris metro (RATP managed infrastructure maintenance site). The difficulties, such as the installation of cranes and construction machinery on a small plot, were raised while limiting noise, visual, olfactory and ensuring the safety of workers. The base of life has been installed on the site of the future SMI not to impede the public space.

This work of 14.5 million euros has been completed in compliance with the deadlines and contributes to the environmental quality of the Eco-district Ardoines stations. The building above ground reveals the technical building of exploitation, draws the eye and thanks to its unusual materiality for an industrial infrastructure and its green roof makes sensitize the residents to the sustainable development.

Well Being :

The infrastructure contributes to the well-being of the inhabitants first of all thanks to its function. The treatment of water is an essential element to allow a pleasant living environment. The equipment also allows the natural environment to be better protected and to deal with the problem of soil waterproofing. Water flows better and is less polluted, improving the quality of life of all inhabitants.

The well-being of the users is ensured by the development throughout the project implementation of the HQE targets listed below to have a ventilated environment, isolated and without overheating.

• Target 8 and 9: hygrothermal comfort and acoustic comfort

Thermal and acoustic comfort are guaranteed by the green roof and wood fiber insulation.

• Target 10: visual comfort

Visual comfort is ensured by the glass roof of 8 m² located on the green roof. It brings natural light into the building and thus decreases its lighting needs.

Social Cohesion :

Through the above-ground building located at the entrance of the city and at the end of the Eco-district Ardoines station, the anti-flood pumping station Vitry-sur-Seine sensitizes residents to sustainable development. The use of recyclable materials on the façade and the vegetated roof recreating biodiversity attract the eye and question passers-by about the function of this building. Thanks to its pedagogical architecture, the infrastructure contributes to the awareness of local residents about the risks associated with floods and water management. The equipment creates a dialogue and social bond.

Preservation / Environmental Improvement :

Infrastructure contributes to the improvement of the environment because its function of particulate water pollution (sand chamber and screen) improves the quality of the latter in the natural environment. Thus the water circulates better and is less polluted. This positively influences the quality of the environment and its biodiversity.

The building also contributes to the improvement of the environment thanks to various elements:

• The use of biodegradable and recyclable facade materials such as aluminum and wood fiber.
• The vision of a green space allowed by its green roof.
• The integration of the building into the overall project of the Eco-district Ardoines station as a green island.
• The limitation of the nuisances generated by the operation of the site for the residents: optimization of the interfaces.
• The restoration of biodiversity thanks to green roofs and planter boxes. The planted aromatics and sedum favor the arrival of insects and birds such as bees, butterflies and beetles.

Resilience :

The anti-flood pumping station at Vitry-sur-Seine was built to respond to the consequences of the natural risk of raising the Seine's level: the rise in the level of the watercourse serving as an outlet for the water network rainwater can prevent the evacuation of precipitated water in rainy weather and create overflow flooding of the sewerage system. This equipment thus makes it possible to overcome the influence of the rising waters of the Seine (isolation valve) and, in rainy weather, to pump the runoff water collected by the sewerage system to reject it in the natural environment.

Its dimensioning and the operation of its equipment are studied to be able to function until a flood of period of return fiftieth. The electromechanical equipment is taken out of water for a flood of period of return centennial. The pumping is sized to be able to evacuate the water from the runoff, on the watershed, of a winter rainfall of decadal return period.

Flood pumping stations play an essential role in returning to normal after a major flood (evacuation of water trapped in the land after overflowing of the watercourse) and allow in rainy weather to ensure the evacuation of water. runoff water (water cycle).

This new facility contributes to improving the quality of life of the inhabitants on a daily basis but also in the event of an exceptional event and contributes to the protection of a rapidly changing neighborhood ZAC Ardoines station (minimizing the risk of flooding through urban runoff).

Responsible use of resources :

The anti-flood pumping station in Vitry-sur-Seine contributes, thanks to its particulate clean-up function (sand chamber and screen), to a rational use of water resources. The energy consumption of its equipment has been optimized to obtain a reasoned consumption.

In order to reduce the energy consumption of the above-ground building and users, insulation of the exterior with wood fiber has been carried out on all facades and roofing. It allows to limit the energy expenses related to the heating or the air conditioning of the building, a better thermal and acoustic comfort and the ilot effect of heat generally generated by the industrial buildings. The green roof also contributes to the improvement of thermal and acoustic comfort. The glass roof of 8 m² in the green roof optimizes energy consumption and brings natural light into the building.
