Collection System Ventilation
Abstract
This study used extensive field studies in the U.S. to look at the strengths and weaknesses of current ventilation models in order to develop future modeling tools. The field experiments resulted in a large database of measured ventilation and related parameters to characterize ventilation in full-scale gravity sewers. The field data were used as input to three current models to evaluate their accuracy compared to the measured field data and the strengths and weaknesses of each model were assessed. Observations from the study were used to develop a concept for an improved ventilation model based on conservation of momentum equations in connected collection system components.
