CMP Part 4B. Sanitary Sewer Plan <br /> Municipal I/I Reduction <br /> Much of the City's sewer infrastructure is over 40 years old, and susceptible to I/I due to their age. <br /> In addition much of the city system runs along lake shore and is susceptible to high water periods. <br /> City code prohibits the discharge of storm water to the sanitary sewer system and requiring the <br /> disconnection of existing I/I sources (Sec. 14-189. - Prohibited discharges of <br /> groundwater/stormwater into the sanitary sewerage system). The city does experience a high <br /> amount of home rebuilds, especially along the lake shore which coincides with a large portion of <br /> the municipal sewer system. All new construction is inspected for possible cross connection as <br /> part of the sewer connection permit process. In addition, the City has routine activities directed <br /> at recognizing and correcting I/I. During the City's annual sewer system maintenance activities, <br /> 20%of the system is cleaned and televised to locate leaks or service connections with continuous <br /> flows. Appropriate corrective measures are then initiated with the affected property owner. The <br /> results of the inspections are used to develop and prioritize the City's sewer rehabilitation projects. <br /> For the past 5 years and programmed in to the future the city allocates 4250,000 per years for <br /> sewer improvement projects to address I&I issues. <br /> City of Orono Community Management Plan 2020-2040 Part 4B, Page 14 <br />
