La problématique client

La principauté a fait le choix d’étendre sa surface sur la mer à travers la construction d’une surface de 6 hectares supplémentaire. Une fois la surface construite, un groupement de travaux publics se charge de la construction des futurs bâtiments. Ce groupement a fait appel à Nomado pour la création d’une station d’épuration de sa base vie de 195 personnes.
Nomado a conçu, réalisé, mis en service et exploite la station d’épuration de la base vie avec rejet en mer. L’enjeu de ce projet résidait dans le traitement de l’azote et du phosphore qui représentait une contrainte importante.
Nomado a donc adapté son process de traitement afin d’obtenir une eau dépolluée et conforme aux exigences en matière de rejet en mer.

Le projet

Nomado a proposé une filière conforme, complète et performante pour la base vie du chantier :
