City of San Leandro <br />Sewer System Management Plan <br />Volume I <br />• Service Calls monthly and annually <br />• Average time to respond to a Service Call <br />• Average response time and clean up time for an SSO annually <br />• Number of plugs in "Hot Spot" assets inspected weekly, monthly or quarterly <br />The City documents all maintenance activity information using the ICOM3 infrastructure <br />management system. Historic maintenance data can be digitally linked to the GIS for analysis of <br />repeat problem areas. This process allows the City to adjust maintenance activities to prevent <br />stoppages and develop reports for annual audits required for the SSMP. The ICOM3 system also <br />manages CCTV inspection data. Inspection data is collected in a format that is compatible with <br />ICOM3. The system allows for developing a history of operations of assets that help identify <br />approaching problems in operation and allow investigation and correction evaluation prior to an <br />Overflow event. <br />The City's total number of SSOs and total volume of spills in calendar years 2011 — 2015 and the <br />first 10 months of 2016 are shown below: <br />Number of SSCs <br />—*—Total Volume... <br />5 3000 <br />4 2500 <br />c <br />0.2 <br />2000 <br />w 3 bn <br />w <br />1500 E <br />3 <br />2 0 <br />3 1000 <br />z <br />1 0 <br />500 <br />0 0 <br />2011 2012 2013 2014 2015 2016 <br />The City's SSMP will be updated when necessary to include operational changes that affect the <br />SSMP elements.
