The application of an aesthetic quality index is proposed for distribution water. This index is expressed by a dimensionless number between zero and ten and it is calculated by a formula in which taste and odour, turbidity and colour take part. A sub-index has previously been defined for each of these parameters and the global index is a weighted average of all of them. The taste and odour are determined by Flavour Profile Analysis.
