We deal with a complex water distribution problem through a bicriteria fair division model over time with network constraints: we aim at distributing water fairly in a cost-efficient manner. The problem is illustrated for the region of Kabylia, Algeria. It involves the optimization of pump operational schedules as well as strategic planning issues. Complex rules establish energy tariffs depending on the time of day and the contractual issues of the pump facilities. We discuss the relevance and implementation of different solution concepts, showing various alternatives that improve upon current management procedures.
