1. Aper\u00e7u du projet<\/h3>

Le projet de traitement des eaux souterraines et d’approvisionnement en eau de la zone franche est un projet cl\u00e9 de d\u00e9veloppement des infrastructures situ\u00e9 dans l’\u00c9tat de Lagos, au Nig\u00e9ria.<\/span><\/h3>

Ce projet, financ\u00e9 et r\u00e9alis\u00e9 par la China Railway Construction Corporation, constitue une infrastructure de base pour la zone franche.<\/p>

Avec une capacit\u00e9 nominale de 3 000 m\u00b3\/jour, le syst\u00e8me utilise les eaux souterraines locales comme eau brute et fournit un approvisionnement en eau domestique et industrielle aux entreprises situ\u00e9es dans le parc industriel.<\/p>

En raison de la forte teneur en fer et en mangan\u00e8se et des importantes fluctuations de la qualit\u00e9 de l’eau souterraine en Afrique de l’Ouest, le projet met en \u0153uvre un syst\u00e8me avanc\u00e9 de purification et d’approvisionnement en eau souterraine afin de garantir un approvisionnement en eau stable et s\u00fbr.<\/p>
