Conjunctive optimal scheduling of pumping and booster chlorine injections in water distribution systems

Research output: Contribution to journalArticlepeer-review


This article extends previous work on optimal booster chlorination injection design and operation in water distribution systems by solving the scheduling problem of pumping units in conjunction with the design and operation problem of booster chlorination stations. Two models are formulated and solved using a genetic algorithm scheme tailor-made to EPANET: Min Cost - for minimizing the costs of pumping and the chlorine booster design and operation, and Max Protection - for maximizing the system protection by maximizing the injected chlorine dose. An example application is explored through a base run and sensitivity analysis showing that the algorithm proposed is robust and reliable, and that the pump and chlorine injection scheduling are mutually connected.
