Abstract Biological corrosion of sewers networks and treatment plants constitutes a serious problem, and its effects result in the loss of billions of dollars per year. Hydrogen sulphide (H2S) gas is the major contributor to the odour and corrosion occurring in the sewer networks. H2S gas is formed by the breakdown of organic matter in the sewer under anaerobic conditions. These emissions not only increase the cost of maintenance but also pose a threat to human health of sewer workers. To understand and to be able to estimate transformation processes at the air-water interface, it is important to study the hydraulics and flow patterns in sewers. For this purpose, a model has been setup in the open source platform OpenFOAM, which is aimed to improve the data basis for a numerical model of natural sewer ventilation.
