► The aim was to choose the best option of sewage system modernization. ► Multi-criteria decision aid methods were used. ► The mathematical model of the decision problem was built. ► In order to obtain an objective ranking of all options the aid method was applied. ► The method has been applied to a real-life problem in Poland. The paper deals with the possibility of application of multi-criteria decision aid methods to selecting best options for municipal infrastructure systems modernisation projects. The subjects of analysis are different open trenching sewage system construction technologies. The aim of the work was to build a mathematical model of the decision problem and apply an existing multi-criteria decision aid method to obtain an objective ranking of all decision options. The method has been applied to a real-life problem in Poland. The results obtained from the analysis demonstrate effectiveness of the adopted method. The presented method can be used by individual designers and managers to decide on selection of the most appropriate technology for modernisation of municipal infrastructure systems.
