Turin Median Collector

Nicknamed the "idropolitana", the Collettore Mediano di Torino [Turin Median Collector] will become the new backbone of Turin's sewage network, running parallel to the existing one. It will extend 14 km under Turin at a depth of 20 metres, connecting the southern part near Moncalieri with the northwestern area, and directing water flow to the Castiglione Torinese sewage treatment plant. This project will tackle climate change related issues, such as the increased mixed f lows that the old collector can no longer support. It will also enable extraordinary maintenance of the current network and play a key role in environmental depollution by transporting mixed and pure quality rainwater, often laden with pollutants, to SMAT's Water Reclamation Centre in Castiglione Torinese, thereby reducing wastewater pollutants and preventing reflux into the River Po. As part of the project, remediation work will tackle the presence of World War II ordnance and environmental upgrades will be made: for every shrub removed to facilitate work along the collector route, a new tree will be planted.
