In the paper, the technical risk has been evaluated for the sewage network of a city in Southern Poland. The basis for calculations were field studies concerning operation of the said network, with the focus on technical data (network type, length, materials, size) and the failure rate information (type and duration of failure, unwanted event frequency). A two-dimensional matrix for failure risk in the pipelines was prepared with consideration to the type of pipeline and the material, as well as a risk map for pipeline malfunction. Obviously, the number of factors may be extended. In order to perform such analyses and add new factors, an appropriate database is needed, while in the case of sewage systems there is still little data collected. The evaluated risk of failure for the studied network was discovered to be in the tolerated and controlled-risk groups. The matrices and technical risk maps can prove to be useful in the process of optimizing the operation of the sewage network, e.g. in planning and executing repair works.
