From today, the Punta Gradelle purifier, which cost 25 million euros and was built inside an enormous karst cavern in the bowels of Punta Scutolo (the promontory that divides Vico Equense from Meta) passes into the hands of Gori after testing and transfer to the Campania Region.
The purifier was built with a sophisticated system of grilles, positioned in the central part of the cave where two large collectors converge, one from the east that conveys the wastewater from Vico Equense and one from the west that collects the wastewater from Meta, Piano di Sorrento, Sant'Agnello and Sorrento.
Both collectors are built underground and covered by real driveways (to be used for inspections) that cross the bowels of the Sorrento Peninsula. As for Sorrento, for now, the sewers of the eastern and central part of the city end up in the purifier. The western part is missing, whose wastewater ends up in the tanks of Marina Grande.
Gori is currently undertaking a major transformation with the construction of the collector that will connect the fishing village to the one leading to Punta Gradelle.

With the addition of the western part of Sorrento, the overall flow of the pipeline will increase by 20%, but there will be no problem because the system has already been calibrated to handle this increase.
A third collector also departs from the screening tanks, all controlled via monitors in the technical room, carrying the purified water to the Punta Gradelle underwater pipeline.
According to the technicians, this is where the liquids end up after the grilling because the process continues through passages in technologically advanced machinery, which use membranes for filtration, then follow oxidation processes, biological ones, up to UV rays.
At this point the crystal-clear water ends up in an underwater pipeline that carries it 1.500 meters from the coast to a depth of about ninety meters.
