La ville de Villennes-sur-Seine (dans les Yvelines (78)) se trouve dans la zone de collecte du SIAAP, c’est-à-dire que les 5282(1) habitants correctement branchés à leur réseau d’assainissement envoient leurs eaux usées à l’usine de traitement de Seine Grésillons

Zone SiaapVillennes-sur-Seine

À Villennes-sur-Seine, la collecte et le transport des eaux usées sont assurés par deux gestionnaires différents. Il se peut, selon votre adresse, que vous soyez branchés à l’un ou à l’autre :

  • La collecte des eaux usées est assurée par la CU Grand Paris Seine & Oise par des réseaux séparatifs
  • Le transport des eaux usées est assuré par le SIARH, jusqu’aux réseaux du SIAAP.

Vous pouvez identifier votre gestionnaire de réseau selon votre adresse directement depuis monbranchement.fr.

La correction des branchements au réseau d’assainissement est essentielle pour protéger la nature et être conforme à la réglementation. Contacter votre gestionnaire vous permettra d’obtenir une aide financière pour les travaux de mise en conformité de votre assainissement collectif.
