The Clichy plant is a key wastewater treatment facility in the Greater Paris area, pretreating effluent from an area measuring 108 km2 with a population of more than two million.
With the surge in urban development, sanitation has become a major global issue that will require a great deal more effort and investment. Each town or city has specific infrastructure requirements, and Artelia uses its wastewater collection and management expertise (networks, storage basins, separate sewerage systems, leak and extraneous water management) to help clients define their individual projects. Artelia is familiar with the problems encountered in rural communities, towns and cities, and for many years has been assisting some of the world's biggest cities with their long-term sanitation projects. Lastly, Artelia also advises its clients with network asset management.
Waste water treatment plants
With extensive experience in the construction of modern treatment installations (compact, non-polluting, low-energy consumption) and design of optimum sludge recycling solutions (anaerobic digestion, composting, storage, etc.), Artelia assists its clients in adapting their infrastructure in accordance with ever-stricter standards (e.g. the European Council directive concerning urban waste water treatment).
Storm water, flood relief basins
Storm water is an increasingly important factor in sizing sewer systems. Artelia studies and builds mathematical models of separate networks and has completed numerous schemes to collect, store, treat and redistribute storm water. Today, temporary storage structures are used to avoid costly over-sizing of networks and limit pollution due to runoff. These large underground storage tanks, which are complex structures from both the civil works and hydraulic standpoints, are one of Artelia’s specialities. Such extensive techniques, based on technologies with low operating costs, are also a major area of innovation in the framework of sustainable development.
The Kesrouane project includes some of the most densely populated parts of Lebanon. Its mountain villages, seacoast hotels and beaches are considered among the most attractive summer resorts in the country.
The project involves the construction of Phase II - Stage II of the WWTP Gabal El-Asfar which handles all domestic and industrial wastewater from the left bank of Cairo.
The Toulouse metropolitan area authority has undertaken to modernise and redesign its wastewater infrastructure in view of the significant population growth the city is experiencing.
