This research provides a first assessment of the location of air pockets in a case study from the literature by using the developed AirSWMM. A pressure-driven analysis is implemented in the source code of AirSWMM(v2.0) to better simulate the nodal demand since this feature was not originally included in SWMM. Pressure-head results for different spatial discretisations are compared with collected field data to assess the best compromise between spatial discretisation and the results’ accuracy. The recommendations from international guidelines for the location of air release devices are compared to the predicted air pocket locations to assess if the numerical estimates are in agreement with the empirical evidence
