Eni Rewind's new plans include the disposal of groundwater treatment (TAF) water directly into the sea , as authorized by the relevant authorities, bypassing the purification plant of the Sassari Provincial Industrial Consortium, which is responsible for treating wastewater from Eni's plant wastewater. The decision has fueled conflict between the industrial giant and the Municipality of Porto Torres , which has expressed a negative opinion at a conference of services. This operation would allow the Eni group to directly discharge into the port's waters the waters treated during the reclamation processes, pumped from surge wells, and the stormwater runoff from the barrier.
The municipal authority has highlighted the risks to determining the nature of any resulting pollution by bypassing the CIPSS treatment plant, which has also expressed an opposition. For Eni, this would mean a financial saving, while for the industrial consortium, it would mean a significant financial loss and the risk of losing jobs. The discharge of the water treated by Eni Rewind into the port sea is carried out through the consortium's treatment plant managed by ASA srl, an in-house company of the industrial consortium. According to Eni, the treated water would have a more than good analytical profile, clean water, as confirmed by the relevant authorities, such as ARPAS and ISPRA, which authorized the procedure.
"There are two levels of concern on this issue," observes Gianfranco Murtinu, territorial secretary of Filctem Cgil, "the first is related to the drop in the delivery of thousands of cubic meters of wastewater, which will impact the invoices of ASA, the company that will suffer the main loss of its support from Eni. With this awareness, ASA was preparing for other projects to contain the projected losses, a situation that concerns us for the well-being of the workers." Some portions of the volumes are used within the Eni Rewind company, after being monitored by external companies, to produce demineralized water for industrial and chemical uses and distributed to Eni subsidiaries Versalis and Matrìca.
