Physical influences on inflow and infiltration in sanitary sewers

Cities across the United States are facing new and tougher laws governing sanitary sewer outfalls. The excessive flows associated with rainfall infiltration and inflow complicate the matter. By building on the work of others, this paper attempts to better identify the components in sanitary sewer systems responsible for inflow and infiltration. The application of regression techniques to the physical parameters and the inflow/infiltration response may provide cities a better picture of what kind of repairs will best eliminate excessive storm water flows in sanitary sewers --Abstract, page iii
