Modernization of Europe’s largest wastewater treatment plant in France

With an operating capacity of 2.1 million m³ of wastewater per day, the Achères treatment plant in northwestern Paris collects approximately 80 % of the wastewater of Paris. This makes the plant the largest sewage processing plant in Europe and the second largest worldwide (after the plant in Chicago).

Within the scope of a modernization and enlargement project, the wastewater treatment plant is being upgraded to comply with the new European Water Framework Directive and to serve the growing population in western Paris.

27,000 m³ of concrete needed for new wastewater treatment plant

Construction work includes two new parallel facilities for the biological treatment of sludge. A total of 27,000 m³ of concrete was needed for the new wastewater treatment plant.

Technique Béton supplied a large range of products. This included a synthetic mould release agent. In addition, the following special products were used: mortar with a high sulphate resistance that is suitable for aggressive environments; mortar used to create a waterproof bond between the concrete cones and the walls and a self-levelling mortar for levelling the floors in the jobsite area.
