Seine-Saint-Denis is “at the rendezvous” for its objectives of cleaning the waters of the Marne, a tributary of the Seine, with a view to making these rivers swimmable for the Paris 2024 Olympic Games, assured its prefect Jacques on Wednesday. Witkowski. ” We are at the rendezvous, barring a major accident. All of the major structures on which we have started work on the entire network, not just in Seine-Saint-Denis, will be completed in time to be operational before the Games,” he declared during a site visit to Gagny on this topic.
Seine-Saint-Denis is one of the players in the bathing plan for the Seine and the Marne, designed for the 2024 Games but intended to last beyond, in which the public authorities have invested 1.4 billion euros. since 2016. For this department in the north-east of Ile-de-France, the main challenge is to modernize the water treatment network in certain areas in the south of the territory to separate rainwater from wastewater, which currently mixes and sometimes flow all at once into the Marne upstream of Paris.
This notably involves the construction of a new 30,000 m3 retention basin in Gagny, which must be completed in the spring of 2024, and the laying of around thirty kilometers of wastewater pipes, which must then be connected. ” The arrival of the Olympic Games allowed us to be a tremendous accelerator, at least for our territory, for this standardizations,” imposed by a European directive, indicated Jacques Witkowski. While all major accounts (administrations, large complexes, public establishments, etc.), which represent three-quarters of wastewater flows, should be connected to the network at the start of 2024, the campaign, on the other hand, is marking time for private connections. .
Of the 10,200 private homes deemed to be a priority, only 1,100 have currently carried out the work required by law. The fault has a non-negligible cost for invisible results (7,700 euros on average, of which 6,000 are covered by public aid). Beyond the Olympic open water swimming and triathlon events in the summer of 2024, the bathing plan should lead to the opening of around twenty permanent bathing sites in Île-de-France in the years to follow.
