Sanitary Sewer System Recommended Improvements <br />This section discusses recommended improvements to address existing sanitary sewer <br />system deficiencies. The improvements are shown in Figure 8 and are summarized <br />below. This section should be updated following the completion and review of data from <br />the City's current CCTV effort. <br />Correction of Deficiencies <br />Pipe Settlement <br />Review of CCTV video footage has revealed a number of pipe settlements in excess of fl- <br />inches. The dip that is created by these settlements cause low velocities and <br />sedimentation of solids which results in on-going sewer maintenance problems. These <br />pipe segments are difficult to repair without removing and replacing the settled sections <br />of pipe. It is recommended that the entire segment from manhole to manhole be replaced <br />for each settled location identified. If possible, the timing of these improvements should <br />be incorporated into the City's street reconstruction program. <br />Root Intrusion <br />• <br />The review of CCTV video footage also revealed a significant amount root intrusion in • <br />the sanitary sewer system. Roots can cause flow restrictions and require continuous <br />sewer monitoring and maintenance. It is recommended that the City implement an on- <br />going sewer rehabilitation program to address this problem. The program would include <br />rehabilitation of the sanitary sewer using trenchless methods for sections identified <br />through CCTV inspections. <br />CCTV Inspection <br />It is recommended that the City implement a CCTV inspection program for the sanitary <br />sewer collection system. This program will allow the City to monitor the system and <br />respond to problems in a proactive manner. <br />Capital Improvement Plan <br />This section summarizes the recommended sanitary sewer system improvements and <br />presents a capital improvements plan that prioritizes the improvements and provides a <br />schedule for the timing of implementation. Budget cost estimates are also summarized. <br />Budget cost estimates are based on 2007 dollars and adjusted annually at 3%.
