Optimisation of sewerage network in the district of Valpantena (Italy)

The district of Valpantena was provided with a primary pipeline of combined sewerage network (length 16 km), which serves the following towns: Dorighi, Bellori, Lugo, Stallavena, Grezzana, Marzana, Quinto and Poiano.

Originally, all the secondary networks were of mixed type, and only Marzana and Quinto were provided with separated foul and surface drainage sewerage systems. The sewage was conveyed to the wastewater treatment plant of the city of Verona.

This situation required the optimization of the sewerage network through the study of four design options:

  • Option 1: strengthening and upgrading of the existing primary pipeline (Total length of intervention: 13 km);
  • Option 2: separation of the two networks, the main collector and the secondary pipelines. Upgrading of the existing network to be used as the new surface drainage sewer and realization of a new foul sewerage network. (Total length of intervention: 48 km)
  • Option 3: separation of the two networks, the main collector and the secondary pipelines. Upgrading of the existing network to be used for foul sewage and realization of a new surface drainage sewerage network. (Total length of intervention: 43 km)
  • Option 4: separation of the two networks, as follows:

Main Sewer: upgrading of the existing network to be used as the surface drainage sewerage and realization of a new foul sewage network;

Secondary Networks: upgrading of the existing network to serve the foul sewage and realization of a new surface drainage sewage network (Total length of intervention: 4 km).

Based on this sensitivity analysis of the facts, the client will choose the solution to be developed in subsequent phases of the project (preliminary, final and detailed design).
