CMP Part 4B. Sanitary Sewer Plan <br /> <br /> <br />City of Orono Community Management Plan 2020-2040 Part 4B, Page 15 <br />Future Sewer Maintenance Needs <br />Orono is committed to maintaining and improving the existing sanitary sewer system. In addition <br />to the normal routine and reactive maintenance operations the city is committed to the following <br />proactive/ preventive maintenance programs: <br /> <br />Table 4B-14: Maintenance <br />Program Description Purpose Annual <br />Budget <br />(2018 $s) <br />Annual sewer <br />cleaning and <br />inspections <br />This project includes the cleaning and <br />inspection (televising) of 1/5 of the <br />City’s sewer mains each year. <br />This project is part of the City <br />preventative maintenance program. <br />The results of the inspection are used <br />to determine future maintenance <br />needs and identify possible sources <br />of I&I. <br />$ 45,895 <br />Annual Lift <br />Stations <br />Inspections <br />All 44 Lift and Grinder stations with in <br />the city are inspected annually. <br />The results of the inspection are used <br />to determine future maintenance <br />needs. <br />$7,000 <br />Sewer <br />Rehabilitation <br />Sanitary Sewer Rehabilitation projects <br />will consist of Cured in Place Pipe <br />(CIPP) lining of infiltration susceptible <br />sanitary sewer pipes, manhole <br />reconstruction, and lid replacement. <br /> <br />Reduce Inflow and Infiltration (I&I) <br />into the Sanitary sewer systems. The <br />lining process creates and new <br />durable pipe within the older pipe at <br />a much reduced cost from open <br />curing or directionally drilling. <br />$ 265,225 <br />Lift Station <br />Rehabilitations <br />This project will rehabilitate 2 of the <br />City’s 46 Lift Stations. Rehabilitation <br />includes the inspection, and <br />replacement of a lift stations piping, <br />motors, pumps and control as well as <br />repairs wet well. <br />Ensure the reliability of the city’s lift <br />station system. Allows City to <br />provide extensive maintenance to <br />each Lift Station once every 22 years. <br />$ 110,000 <br />Backup Generator <br />Installation <br />This project will provide a backup <br />generators for 2 Lift Stations per year. <br /> <br />This project is part of a systematic <br />effort to provide backup power to <br />critical City infrastructure. <br />$ 150,000 <br />Sewer System <br />Monitoring <br />This project will see the provision of <br />electronic monitoring of 4 additional <br />Lift Stations per year. This project will <br />upgrade/replace components of the <br />monitoring system including antennas, <br />cabling, and uninterruptable power <br />supply (UPS). <br />This is a continuation/ expansion of <br />the project begun in 2016. As of <br />2017 the city has 30/46 lift stations <br />being electronically monitored. The <br />provision of electronic monitoring <br />for all of the city's lift stations will <br />improve response time to issues, <br />reduce backup incidents and provide <br />real time monitoring and reporting <br />for accountability. <br />$ 26,000 <br /> <br />
