Abstract:

This paper describes the airflow modeling work for the City of Los Angeles (City) main interceptor system, which was performed as a part of the City's comprehensive sewer airflow study. Two separate airflow modeling approaches were used. The first approach was empirical and provided the capability to estimate drag-induced airflow rates and identify potential locations of positive sewer air pressure. The second approach was theoretical and calculated airflow rates and pressures, and simulated the impact of structures and facilities. A comprehensive field pressure sampling and monitoring study was undertaken to understand the dynamics of airflow in the main interceptor system and furnish the required data for the airflow models. In addition, extensive tests on a scale physical model of one the main sewer drop structures were performed to support the study. The models and findings of this study advance the understanding of airflow in gravity sewer systems with the objective of minimizing odorous gas emissions.
