Successful water accounting does not eliminate conflict, but it confines water conflicts within a legal and technical framework where they can be more efficiently addressed, with a minimum of chaos. In successful water systems, most water users (households and farms) see only the price of water use and any rules restricting use, and are not actively engaged in water accounting.
