The Hydraulic Capacity of Deteriorating Sewer Systems
Original language description
Sewer and wastewater systems suffer from insufficient capacity, construction flaws and pipe deterioration. This paper presents the results of a research focused on the study of hydraulic effects caused by failures due to temporal decline of sewer systems. Hydraulic simulations are usually done running commercial models that apply, as input, default values of parameters that strongly influence results. Using CCTV inspections information as dataset to catalogue principal types of failures affecting pipes,a 3D model was used to evaluate their hydraulic consequences. The translation of failures effects in parameters values producing the same hydraulic conditions caused by failures was done through the comparison of laboratory experiences and 3D simulations results. Those parameters could be the input of 1D commercial models instead of the default values commonly inserted. This will move the results from 1D models closer to reality and decrees a number of calibrations needs.
