A sewer that surcharges during a rain storm can be caused by either too much Infiltration/Inflow (I/I) or some type of restriction. Flow meter data often provides the only clue to what is happening. Engineering Consultants and Agencies have each developed their own methods for extracting engineering knowledge from flow data and there is little assurance that an analysis conducted by one engineer in one city can be compared directly to that done by an engineer in another city.

WERF Project (99-WWF-8) studied I/I removal programs around the US and found that their efforts to acquire detailed analysis was unsuccessful for many utilities because information was not generated and archived suitably or that the data were incomplete or unreliable. The mismatch of methods and procedures for evaluating I/I creates a lack of uniformity among agencies performing the sewer rehabilitation. This paper describes an engineering solution that allows anyone with flow and rain data to develop standard analyses.
