About the Company

Une entreprise publique unique en Europe
Son périmètre d'intervention englobe quatre départements et 180 communes reparties sur quatre autres départements, le SIAAP est :
- le seul syndicat interdépartemental d’assainissement des eaux en Europe;
- la première entreprise publique à l'échelle de la première métropole européenne par la densité de sa population

Le SIAAP transporte dans son réseau souterrain et "lave" l’eau utilisée par près de 9 millions de Franciliens pour leurs usages domestiques et industriels – ainsi que les eaux pluviales. Une fois dépolluée dans les 6 usines du SIAAP, l’eau est rejetée dans la Seine et la Marne.
Couvrant un territoire de 1 980 km2, le SIAAP traite chaque jour près de 2,5 millions de m3 d’eaux usées par temps sec. Ce volume peut augmenter brutalement en cas de fortes pluies, quand les eaux ruissellent sur le sol et se déversent dans le réseau d’assainissement. La bonne gestion de ces eaux nécessite des compétences de pointe et des moyens de prévision et de traitement adaptés.
Le SIAAP agit concrètement pour la protection du milieu naturel, le développement durable du territoire et pour la biodiversité.
