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 to increasingly stringent standards (e.g. the European Council directive concerning urban waste water treatment). Artelia is assisting the Paris region water authority, SIAAP, to bring the Upper Seine treatment plant at Valenton (3,600,000 PE) into line with European standards and is providing design and construction supervision services for several other treatment plants in France. On the west coast of Mauritius, Artelia studied the feasibility of a treatment plant close to a very fragile lagoon. In Palestine, Artelia is designing a waste water infiltration system at Khan Yunis. Artelia’s team of experts built a 3D hydraulic model of flow distribution in the screens and grit traps at the Achères treatment plant in the Paris region in order to optimise its operation.
