The main objective of this study consists of determining the efficient price of water t o be intended for the irrigation of Apodi Project -CE. It was used a demand curve of water in a short term, obtained by residual method. It was either estimated the flexibility of derived demand for water, which is a parameter of considerable economic interests. The operational costs and the income of selected cultures were raised by Secretary of Irrigated Agriculture of Ceara State – SEAGRI, concerned on the second semester of 2000. These data had been complemented by results of researches on the subject and by informations conceded by FAPISA (Federation of Irrigated Projects Associations of Jaguaribe – Apodi). Results indicated that the resultant signaling of the efficient price is one of the most precise ways to assure the rational use of water, being able to take the producer substantial profits, besides it is a effective instrument for management of irrigation projects. The study also indicated that the contribution of water for the raw income was of 32,6%, being the remainder available to fixed factors.
