City of San Leandro <br />Sewer System Management Plan <br />Volume I <br />P a g e | 18 <br />defect causes complete line failure. These guidelines should be verified by actual research under <br />prevailing local conditions. <br />5 –Pipe has failed or will likely fail within the next five years <br />4 –Pipe will probably fail in 5 to 10 years <br />3 –Pipe may fail in 10 to 20 years <br />2 –Pipe unlikely to fail for at least 20 years <br />1 –Failure unlikely in the foreseeable future <br />After assessment is complete, CCTV videos are uploaded both to ICOM3 and to the t4 Spatial <br />program. t4 Spatial is a cloud-based program that displays Collection System assets, and <br />correlates video to a specific line segment. <br />Each frame in the video can be associated with a specific location on the GIS map.City <br />Engineering Department staff can search for pipe segments with PACP grades of 3 or higher and <br />view specific portions of video that reveal problem locations of the pipe. This allows the City to <br />put together an accurate list of sewer line point repairs and replacements needed for the <br />following fiscal year.Also, repairs are completed more efficiently due to the City’s ability to <br />provide very accurate locations to contractors for required repairs.
