Weekly inspections include visual check of the <br />equipment, manual cycling of pumps, checking and cleaning floats, recording hour meter <br />readings, and cleaning off debris. <br />Pump stations are inspected extensively every year. Extensive maintenance includes cleaning out <br />of sump, and removing pumps far inspection and repairs if necessary. <br />SSO Abatement <br />Data indicate that the large majority of stoppages and SSOs are caused by roots and grease in the <br />sewer. The City employs a comprehensive cleaning program for its sewers as a primary means of <br />SSO abatement. The program cleans sewers every year. Information about the maintenance <br />requirements of the pipes are managed and evaluated using the capabilities of the City's ICOM3 <br />CMMS. Some sewers are included in a focused cleaning program (hot spots). <br />The City evaluates the effectiveness of sewer cleaning in removing roots and grease by <br />performing post-cleaning CCTV inspection or by monitoring the amount of debris removed from <br />the system on a continuing and comparable basis. <br />Other Recommendations <br />In addition to capital costs associated with the correction of capacity and structural deficiencies, <br />other needs far the City's collection system have been identified.
