The project "Modernization of damaged sections of primary adductors Triolo Foggia, Anello a Sud di Foggia, 5B" provides for the safety of some sections of the aforementioned adductors by replacing existing pipes in C.A.P. with homologous steel pipes, where possible, or alternatively, in the most critical areas due to the proximity of civil settlements and interference of various kinds, through no dig techniques of "slip lining", consisting in the insertion of steel pipes of smaller diameter in the existing pipes in C.A.P. and in the subsequent clogging of the cavity with special mortars with high fluidity. The project also provides for the restoration of some steel hanging sections, located along the branches subject to intervention, characterized by an advanced state of deterioration.
