The VL8 collector will connect the V10 stormwater ogee (in Athis-Mons) to the S\u00c9SAME pumping and purification station (in Valenton). The project has multiple objectives: to strengthen and secure the sanitation network, but also to avoid the risk of discharge into the natural environment. The project is also contributing to ensuring that the Seine is \u201cswimmable\u201d by the 2024 Paris Olympic Games.<\/strong><\/p>\n<\/div> The project has multiple objectives: to strengthen and secure the sanitation network, but also to avoid the risk of discharge into the natural environment.<\/strong> The project is also contributing to ensuring that the Seine is \u201cswimmable\u201d by the 2024 Paris Olympic Games.<\/p>\n Work package 0 includes the various shafts (entry, exit and reversing tunnel) for the tunnel boring machines. Work, which is mainly within four sectors, began in October 2020 with the confirmed Valenton phase, in the SIAAP water treatment plant.<\/p>\n The teams of the consortium led by Soletanche Bachy France<\/a> have been involved in development work since October 2020, including an access road independent of the plant, a fence, a sanitation system and a work platform. This work also included the construction of a modular retaining wall 70m long and 6m high. This solution was proposed by the consortium and accepted by the SIAAP, allowing the removal of a containment mound present on the site of the future\u00a0diaphragm wall<\/a>.<\/strong><\/p>\n<\/div>
