Under the terms of the EPA Water Pollution Control Legislation, cities must eliminate excess infiltration/inflow to be eligible for 75% EPA sewerage construction grants. To determine the amount of excess rain and ground water in a system, an extensive analysis of the system is required. Why bother? Because inflow of rainwater and groundwater can increase peak storm loads into the treatment plant tremendously. This article describes how to perform an infiltration/inflow analysis and includes a case history of an analysis and a sidebar summarizing a 28-city survey of analyses.
