The hydraulic and geomorphological redevelopment works of the Rio Pedrugnanu, in Sorso, have officially begun, included in the program agreement between the Ministry of the Environment and the Region of Sardinia. For the works, which will be concluded by March of next year, the Municipality of Sorso has obtained a total funding of 2 million euros.
The planned interventions will focus in particular on three sections of the river. First of all, we will proceed with the backfilling, that is, the partial removal of the covering of the existing covered canal near the Maiori wash house, and with the subsequent installation of overpressure grids in the residual part of the canal. We will then proceed with the reconstruction of the riverbed, replacing parts of the existing bottom with reinforced concrete structures and adequate hydraulic sections in the section between Via Siglienti and the bridge of Via Castelsardo, near the entrance to the industrial area. In the Predugnanu area, a section of the riverbed will be renovated with reinforced concrete structures at the point where the sewer pipe crosses. A second section will be rebuilt with stone structures near the road crossing, which will be rearranged to adapt it to the new hydraulic section of the river. Vegetation will also be removed along the critical points.
These interventions on the main stretch of the Rio Pedrugnanu are part of a broader framework of hydraulic redevelopment, which has already seen the conclusion, in December 2023, of the consolidation and reinforcement works on the banks of the left tributary. The latter crosses the countryside adjacent to the town for 350 meters before flowing into the main course of the Rio Pedrugnanu. The works on the left tributary included the general cleaning of the riverbed and the construction of protective reefs. These interventions have led to a substantial improvement in the water regulation system, reducing the risk of flooding and protecting the surrounding area from potential hydrogeological damage.
