Our stormwater treatment solutions for transport infrastructures
Regulating and treating stormwater in transport infrastructures is a major challenge for safety, sustainability and the environment. Whether for airports, ports or rail networks, effective stormwater management is essential to guarantee the smooth operation of facilities, protect natural resources and prevent pollution risks.
What are the main issues involved in treating and regulating stormwater in transport infrastructures?
Transport infrastructures generate large areas of waterproofing, on which pollution is deposited, consisting of particles (SS), hydrocarbons, organic matter, chemicals, heavy metals and other hazardous substances. Inadequate treatment of this water can have harmful consequences for the environment, including soil and groundwater contamination, algal blooms and the destruction of natural habitats.
These issues raise major challenges for transport infrastructures, which must :
- Guarantee continuity of service, quality of service and customer satisfaction, by avoiding disruptions, delays or incidents related to water management.
- Optimize operating, maintenance and renovation costs, by reducing the need for water (especially during periods of water restrictions), energy and treatment, and extending the lifespan of infrastructure and equipment.
- Protect the environment, biodiversity and public health, by limiting pollutant discharges, resource consumption and greenhouse gas emissions.
What regulations apply to the treatment and regulation of water in transport infrastructures?
Road infrastructure is subject to the European Union’s Water Framework Directive (WFD), which aims to achieve good ecological and chemical status of surface and groundwater, and requires transport infrastructure operators to comply with water quality and quantity objectives, and to project-specific prefectoral decrees, imposing quantity (flow) and quality constraints.
The decree of February 2, 1998, amended by the decree of February 28, 2022, relating to water withdrawals and consumption, as well as emissions of all kinds from facilities classified for environmental protection and subject to authorization, will also apply.
A water pre-treatment facility, such as a hydrocarbon separator, can meet the need for at-source management of effluent contaminated with sludge and hydrocarbons; the applicable standards are EN 858, NF16-442 and NFP 16-451-1/CN.
