A Practical Statistical Method to Differentiate Inflow and Infiltration in Sanitary Sewer Systems

2022 | Robert B. Sowby and Daniel R. Jones

Municipal sanitary sewer systems receive unwanted inflow and infiltration (I/I) that adversely impact their sizing, economics, and operation. Here, a practical regression model of daily sewer flow is developed with discrete terms for sanitary flow, groundwater infiltration, direct inflow, and delayed inflow to help practitioners characterize I/IĀ and improve sewer system performance.
