Optimal Simultaneous Design and Operation of Multi-Quality Water Distribution Systems Under Unsteady Hydraulics

This paper extends previous work on management of water distribution systems by explicitly addressing the design and operation problem of quantity, pressure, and quality simultaneously under unsteady hydraulics — a problem that has not been solved yet. The methodology is a straight forward genetic algorithm formulation linked to EPANET with the decision variables been the pipe diameters, the unit pumps heads and maximum power, the tanks storages, and the treatment plants operations and constructions. An illustrative example is explored showing high potential to real world design problems involving quantity, pressure, and quality explicit considerations.
