IV. PHYSICAL INSPECTION DATA AND ANALYSIS <br />A. Defect Analysis <br />1. Introduction <br />This section describes the types of defects located during the field investigations <br />of the Paris wastewater collection system. Table IV-1, page IV-2 summarizes the <br />defect totals, I/I quantified for the defects, and the estimated rehabilitation costs <br />by defect category. These totals include both maintenance and I/I related defects. <br />2. Public Sector Defects <br />Public sector structural defects and I/I source defects are associated with <br />manholes, mainlines, and municipal service lines. A total of 4,321 manhole, <br />2,029 mainline, and 207 municipal service line defects were identified during the <br />study. The majority of mainline defects are associated with mainline point repairs, <br />replacement of mainlines, and minor defects requiring scheduled maintenance and <br />repairs. The total estimated rehabilitation cost for public sector defects is <br />approximately $8,000,000. <br />3. Private Sector Defects <br />Private sector defects accounted for 580 of the defects identified in the study. <br />Defects associated with cleanouts and breaks in the service line account for the <br />majority of needed repairs. It is important that the private sector defects be <br />addressed and then properly repaired for a successful comprehensive I/I reduction <br />program. The total estimated repair cost associated with private sector defects is <br />approximately $205,000. <br />ADS Environmental Services, Inc. <br />IV-1 <br />
