The paper presents the methodology formulated for determining the critical technical state of operating sewer pipes which is based on statistical-stochastic modeling. It describes the theoretical boundary between the area comprised of pipes that do not show any signs of damage or require only maintenance measures, and the area comprised of pipes that require renovation. The study includes concrete collectors with dimensions of DN 600/1100-900/1350 mm, stoneware pipes (DN 200-400 mm), and stoneware connections (DN 100-200 mm). The modeling phase was carried out using the Weibull distribution in combination with Monte-Carlo mathematical simulations.
