Rain, again and again, and a situation that is starting to deteriorate. This Wednesday evening, Syage, the joint union in charge of rainwater management in 120 municipalities in Essonne, Seine-et-Marne and Val-de-Marne, feared “an intense episode of flooding”. According to these specialists, the latter could occur Friday evening if water continues to fall in abundance.
“The situation is not good,” squeaks President Romain Colas, also mayor of Boussy-Saint-Antoine in Essonne. 25 ml of water has already fallen on the watershed, which is the equivalent of a month’s precipitation in 24 hours. You should know that one milliliter corresponds to one liter of water per square meter. In addition to these 25 ml that have already fallen, we are told of an additional 45 ml for the next 24 hours. »
Yerres private hospital under surveillance
Problem is, soils that are already waterlogged no longer absorb anything. Floods are therefore to be feared, particularly in Yerres where Réveillon threatens several homes, but also in Quincy-sous-Sénart, Boussy-Saint-Antoine, Épinay-sous-Sénart, Brunoy, Crosne, Montgeron and Yerres where the private hospital is particularly monitored. “What will happen this night will be decisive,” concludes the president of Syage.
As a direct result of this bad weather, traffic was also interrupted on several flooded 91 roads. Diversions have thus been put in place by the department’s services on the RD 988 in Forges-les-Bains, on the RD 27 between Saint-Maurice-Montcouronne and Le Val-Saint-Germain but also on the RD 18 in Monnerville and the RD 60 to Vauhallan.
Crisis units in Orsay and Longjumeau
“At 7 p.m., around fifteen interventions linked to bad weather had been recorded,” indicates the Essonne departmental fire and rescue service. This mainly involved drying out cellars in Forges-les-Bains and Gif-sur-Yvette. » In Morsang-sur-Orge, where the rivers have burst their banks, access to the park has been closed.
According to our information, the municipalities of Orsay and Longjumeau bordered by the Yvette have preventively activated their crisis unit. Champlan and Le Coudray-Montceaux have launched their municipal protection plan and Bures-sur-Yvette provides all-night service for residents who may be affected.
