As far as the water service is concerned, the main risks are due to: inefficient operational management of the water resource, which could cause high levels of losses with consequent excessive consumption; lack of control of the parameters of the resource with environmental consequences if they are exceeded; inadequate interventions on the sewerage-treatment system with possible contamination of the soil and water bodies; risks of fires and explosions in treatment plants related to the production of biogas, with possible impacts in terms of emissions into the atmosphere.
