a été une orientation professionnelle et une motivation supplémentaire pour ma poursuite d'étude en Génie civil. Summary of work done During my training, I had the opportunity to work on the project of improvement of wastewater and stormwater infrastructure at the SSR national hospital. I was asked to calculate the levels of pipes and drains using automatic level and to take offset measurements. I had to inspect formwork and structure of drains and manhole covers.

_ {draw:frame} _ Constructed wetlands or phytoremediation: This is a technology for treating stormwater or wastewater. A constructed wetland consists of a gravel bed on which suitable wetland plants are grown. As water passes through the substrate, it is purified through the activity of bacteria attached to the gravel, plant roots, soil and other particles. Quelles sont les limites de l’assainissement de l’eau des piscines naturelles par les plantes ? L’eau est purifiée par les racines

objective: the decrease of the energy consumption about 20% in 2020. The firm gives a high importance to the Security and the Environment, and does not hesitate to invest several millions Euros for the realization of new objectives such as: Wastewater disposal Reduction of atmospheric broadcasts Improvement stocking (Raw materials and wastes) Reduce the noise In 2008, Vallourec has invested € 28.4 millions in Security & Environment, it represents 5.25% of the total
