This article discusses how optimization modeling provides engineers with a flexible and intelligent tool to achieve their water supply goals in the most cost‐effective manner. The article discusses a case study of using Haestad Methods' Darwin optimization technology to calibrate a water distribution model for the city of Guayaquil, Ecuador. The city hired Envirosoft and its local affiliated company Aquatec S.A. to develop an effective action plan for various tasks that included: an expansion program to manage installation of the required water and sewer connections; the design of new water and sewer networks; 30‐year master plans for the water, wastewater, and drainage systems; and, an action plan for the reduction of unaccounted‐for water. Envirosoft adopted WaterGEMS and Darwin software for hydraulic network simulation and optimization modeling. The goal of the project was to build an accurate hydraulic model of the water distribution network.
