La ville de Médan (dans les Yvelines (78)) se trouve dans la zone de collecte du SIAAP, c’est-à-dire que les 1375(1) habitants correctement branchés à leur réseau d’assainissement envoient leurs eaux usées à l’usine de traitement de Seine Grésillons

Zone SiaapMédan

À Médan, 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.

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.
