The collection of water destined for purification

The extraction of superficial and underground waters takes place with regard to the prescriptions of the specific extraction licences for each system/source. These licences impose specific quantitative time and space limitations in order not to compromise the quantitative equilibrium of the water bodies and their use for other purposes.

Specifically, with regard to tackling subsidence, for several decades environmental policies and investments have led to significantly replacing the use of groundwater with surface water in order to regain and stabilise piezometric levels.  In this way, the Water Service has contributed to significantly reducing the trends of subsidence in many areas, especially the Bologna and Ravenna plains. The most significant works, which started in the 1980s, were:

  • the Reno Aqueduct which allowed the substantial use of the waters of the Setta and the Reno rivers for the supply of the major mains water system that serves Bologna and many municipalities in the Bologna Apennine plains and valleys; this replaced the underground waters of the Reno, Savena and Idice river fans;
  • the Romagna Aqueduct, centred on the Ridracoli Dam and on the Ravenna purification plant (NIP), which allowed the significant use of the Bidente, Reno and Lamone rivers to supply the mains water system that serves a large part of the provinces of Forlì-Cesena, Ravenna and Rimini; this replaced the underground waters of the Romagna river fans, the most important of which were those of the Marecchia River, which serves the Rimini area.
