Hydrogen sulfide (<i>H</i><sub>2</sub><i>S</i>) generated in sewer networks induces corrosion which today constitutes the main cause of deterioration of concrete pipes. Information regarding the <i>H</i><sub>2</sub><i>S</i> concentration inside sewer networks, as well as its control and reduction, has become one of the most important concerns in sanitation systems management nowadays. Modeling sulfide dynamics is the key to understanding corrosion processes. A dynamic model (called EMU-SANETSUL) was developed to calculate the <i>H</i><sub>2</sub><i>S</i> concentration in both the water and the gas phases of the main sewers of the city of Murcia (Spain).
