THE CONSTRUCTION AND UPGRADING OF THE INFRASTRUCTURE OF THE SEWAGE SYSTEM IS AN INTEGRAL PART OF THE ENVIRONMENTAL REHABILITATION OF THE PORT OF NAPLES AND Ê AN ELEMENT OF CRUCIAL IMPORTANCE FOR THE ADAPTATION TO EXISTING NATIONAL AND COMMUNITY LEGISLATION ON DISCHARGES OF WATER INTO THE SEA. A SEPARATE WASTE WATER COLLECTION NETWORK AND A BLACK WATER COLLECTION NETWORK. THE NEW NETWORK OF BLACK PORT WATERS WILL BE LOCATED ALONG THE MAIN PORT ROADS AND WILL BE CARRIED OUT IN A VACUUM, IN ORDER TO LIMIT THE EXCAVATION PROCESS AND ENSURE THE HYDRAULIC FUNCTIONING EVEN IN THE ABSENCE OF SIGNIFICANT GEODETIC LEVELS. THE EXISTING SEWERAGE NETWORK IS CONVERTED ENTIRELY FOR THE COLLECTION OF RAINWATER ONLY IN RESPECT OF WHICH IT IS INTENDED THAT THE TREATMENT OF DE-OILING AND A SUBSEQUENT FILTRATION BEFORE IT IS DISCHARGED INTO THE SEA.
