The attitudes of households towards saving water must be known and understood in order to generate sustainable behaviour in the use of this resource, as currently this behaviour is not being seen. This study examines whether households (18% of total water distributed), of different sizes and spanning a range of ages in terms of the head of the household, display attitudinal differences towards saving water. It also examines the extent to which attitudes and the aforementioned structural variables affect consumption. Using a sample of 500 subjects from the "Vega Baja del Segura" district, a consistent, valid, reliable and parsimonious scale is constructed to measure attitude. The findings show that attitude encompasses two factors which act differentially. Similarly, it is found that attitude towards saving water and household size explained 23.5% of real consumption in households.
