I/I Quantification <br />During the field investigation activities, data was collected to quantify I/I assigned <br />to each located non-structural defect. The PIPE° source defect model used the <br />survey data to compute an I/I quantity based on a potential leak rate. The source <br />defect model is a useful tool to prioritize defects for subsequent repairs based on <br />the amount of UI each contributes and its cost to repair. All defects should be <br />scheduled for eventual repair since they will worsen with age, creating more <br />severe problems. The priority ranking assists in managing the rehabilitation <br />spending. Section VI in this report discusses defect quantification and I/I <br />measurements in more detail. <br />B. Cost Analysis and Recommended Rehabilitation <br />This section of the report presents a cost analysis to prioritize the problems that were <br />located during the study. <br />1. Cost of Rehabilitating Problem Line Segments <br />For each defect(s), it is necessary to establish a repair method and estimate the <br />cost of rehabilitation. The rehabilitation cost estimates are based on current costs <br />for sanitary collection system rehabilitation and construction, but do not take into <br />ADS Environmental Services, Inc. <br />IV-2 <br />
