Water quality is a problem in many urban centres. Though in Spanish cities water supply fulfi ls the minimal legal requirements, in some occasions, its negative social perception induces citizens to adopt defensive behaviours. The economic theory advocates that defensive costs supported by citizens can be considered as benefi ts linked to quality improvement. This is the case of Zaragoza where supply infrastructures dated from the 18th century are still being used. At present, a project is being developed to change infrastructures and improve water quality. The fi nancial costs of this project are already known, however, the corresponding social benefi ts are unknown. The value of these benefi ts has been estimated by a survey of households on the social profi tability of this project. Precise values as well as value functions have been evaluated for three defensive behaviours. Results confi rm the high social profi tability of this public intervention. La calidad del agua es un problema en numerosos núcleos urbanos. Aunque en las ciudades españolas el agua para abastecimiento cumple los requisitos legales mínimos, en algunas ocasiones su negativa percepción social provoca que los ciudadanos adopten comportamientos defensivos. La teoría económica preconiza que los costes defensivos que soportan los ciudadanos pueden considerare benefi cios ligados a la mejora de la calidad. Este es el caso de la ciudad de Zaragoza que utiliza aún infraestructuras de abastecimiento que datan del siglo XVIII. En la actualidad se está llevando a cabo un proyecto de renovación de infraestructuras que mejorará la calidad del agua. De este proyecto se conocen sus costes pero se desconocen los benefi cios sociales que puede proporcionar. A partir de los datos de una encuesta a los hogares se ha procedido a estimar el valor de estos benefi cios para determinar la rentabilidad social del proyecto. Se han estimado tanto valores puntuales como funciones de valor para tres comportamientos defensivos. Los resultados confirman la alta rentabilidad social de esta actuación pública.
