La production d\u2019eau potable de la M\u00e9tropole de Lyon prochainement perturb\u00e9e par une op\u00e9ration de nettoyage – LyonMag<\/p>\n
Pour la deuxi\u00e8me quinzaine de mai, une op\u00e9ration de nettoyage du barrage de Verbois va modifier la production d\u2019eau potable de la M\u00e9tropole de Lyon.<\/strong><\/p>\n Entre le 15 et le 27 mai prochain, la production d\u2019eau potable du Grand Lyon sera modifi\u00e9e et impactera quelques communes de l\u2019Est lyonnais. En cause, une grande op\u00e9ration de nettoyage du barrage de Verbois, qui est situ\u00e9 sur le Rh\u00f4ne, \u00e0 proximit\u00e9 de Gen\u00e8ve (Suisse). Ce processus, qui intervient tous les trois \u00e0 quatre ans, vise \u00e0 \u00e9vacuer l\u2019argile, le limon ou encore le sable accumul\u00e9s dans la retenue de ce barrage, afin de r\u00e9duire le risque d\u2019inondation dans la ville suisse.<\/p>\n Un impact important sur la qualit\u00e9 de l\u2019eau ?<\/p>\n Probl\u00e8me, \u00ab\u00a0cette op\u00e9ration entra\u00eene une augmentation temporaire des concentrations en s\u00e9diments dans le fleuve, limit\u00e9e \u00e0 un taux r\u00e9glementaire moyen de 5 grammes de mati\u00e8res en suspension par litre, l\u2019\u00e9quivalent d\u2019une cuill\u00e8re \u00e0 caf\u00e9\u00a0\u00bb, comme l\u2019explique la pr\u00e9f\u00e8te du Rh\u00f4ne dans un communiqu\u00e9 publi\u00e9 en collaboration avec la M\u00e9tropole et l\u2019Eau du Grand Lyon.<\/p>\n Deux captages secondaires seront ainsi remis en service pour prendre le relais du captage principal de Cr\u00e9pieux-Charmy, dont la production va \u00eatre r\u00e9duite de 50% pendant l\u2019op\u00e9ration, et distribuer les 220 000 m3 d\u2019eau par jour n\u00e9cessaire. Ils feront l\u2019objet d\u2019une surveillance renforc\u00e9e, avec plusieurs analyses de l\u2019eau par semaine.<\/p>\n La M\u00e9tropole de Lyon pr\u00e9cise qu\u2019il n\u2019y aura pas de recommandations sp\u00e9cifiques, ni de restrictions d\u2019usage de l\u2019eau pendant la derni\u00e8re quinzaine du mois de mai.<\/p>\n","protected":false},"excerpt":{"rendered":"La production d\u2019eau potable de la M\u00e9tropole de Lyon prochainement perturb\u00e9e par une op\u00e9ration de nettoyage – LyonMag…\n","protected":false},"author":2,"featured_media":96660,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1889],"tags":[1111,11,2813,2190,2430,1109,251,1112,2811,1777,674,118,1011,27,1922,1110,1114,2428,2810,12,241,316,25,2812,517,800],"class_list":{"0":"post-96659","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-lyon","8":"tag-actu","9":"tag-actualites","10":"tag-article","11":"tag-asvel","12":"tag-auvergne-rhone-alpes","13":"tag-breves","14":"tag-culture","15":"tag-depeches","16":"tag-economique","17":"tag-eu","18":"tag-europe","19":"tag-faits-divers","20":"tag-fr","21":"tag-france","22":"tag-info","23":"tag-informations","24":"tag-infos","25":"tag-lyon","26":"tag-lyonmag","27":"tag-news","28":"tag-ol","29":"tag-politique","30":"tag-republique-francaise","31":"tag-sociale","32":"tag-sport","33":"tag-transports"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@fr\/114500229112966508","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/posts\/96659","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/comments?post=96659"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/posts\/96659\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/media\/96660"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/media?parent=96659"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/categories?post=96659"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/fr\/wp-json\/wp\/v2\/tags?post=96659"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
