La ville de Montigny-le-Bretonneux (dans les Yvelines (78)) se trouve dans la zone de collecte du SIAAP, c’est-à-dire que les 32929(1) habitants correctement branchés à leur réseau d’assainissement envoient leurs eaux usées à l’usine de traitement de Seine aval
Zone SiaapMontigny-le-Bretonneux
À Montigny-le-Bretonneux, 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 CA Saint-Quentin-en-les Yvelines (78) par des réseaux séparatifs
- Le transport des eaux usées est assuré par HYDREAULYS, 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.
