La ville de Nanterre (dans les Hauts-de-Seine (92)) se trouve dans la zone de collecte du SIAAP, c’est-à-dire que les 95105(1) habitants correctement branchés à leur réseau d’assainissement envoient leurs eaux usées à l’usine de traitement de Seine aval

Zone SiaapNanterre

À Nanterre, 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 l'EPT - Paris Ouest La Défense par des réseaux unitaires
  • Le transport des eaux usées est assuré par le Conseil Départemental des Hauts-de-Seine, jusqu’aux réseaux du SIAAP.

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.
