The paper presents the first national WTP/WTA survey conducted in Italy; moreover, the structure of the survey, allows us to study how information given to participants allows to update perceptions and hence WTP. By means of the Reasoned Action Approach, we identify the main determinants of WTP, and how those evolves thanks to information: generally it helps in empowering participants’ inclinations. We observe also misperception between "objective quality" and "perceived quality"; the knowledge of the Water Supply System reduces the misperception, and increases the WTP. Moreover the paper shows that participants exposed to information, update their WTP upward, choosing to sustain service’s quality. Channels which are crucial in shaping these decisions have to be found in the cost of the proposed improvement, in the current level of satisfaction and in the trust citizens are putting in water utilities. To conclude, information can be used to build tariff that tackles simultaneously sustainability from three different perspectives: social, financial and environmental; such an approach is calling also for a more engaging relationship between the stakeholder.
