Knowing the consumer behavior, in this regard, is the first and the most important step. In this study, to reach this objective, the function of household water demand in structure of block pricing in Tehran was estimated by using household budget data , through discrete – continues choice model and maximum likelihood approach . The results show that price and income parameters have expected sign.
