Water supply management in urban areas is not simple because it involves several aspects that a decision-maker needs to address simultaneously. Due to their high complexity, problem structuring methods are adequate to provide a better understanding and to guide the decision-maker towards more assertive decisions. For this purpose, this work proposes the Value-Focused Thinking (VFT), an approach that focuses on the values and preferences of the decision-maker, generating alternatives which are ordered through its performance in a multiattribute value function. This model is applied with a consumer representative of the population of Olinda city, Brazil. Therefore, it presents deeply the characteristics of the local water supply system, according consumer's perspective, in order to direct the water company manager to a more efficient decision-making.
