<br />Sanitary Sewer <br />The existing condition of the sanitary sewer system was acquired from as-built information, <br />sewer video tapes and manhole inspections. The following is a table of the existing sanitary <br />sewer with information on pipe size, material and any problems noted during the televising. <br /> <br />Street Sanitary sewer size Pipe material Problems <br />Asbury A venue 8" Clay Circular cracks, heavy roots <br />Ridgewood Road 8" Clay Circular cracks, heavy roots <br /> <br />Storm Sewer <br />Neither street under consideration has existing storm sewer. There are catch basins located at the <br />intersection of Ridgewood Road and Glenhill Road that drain to the north into the wetland area <br />east of Ridgewood Road. This system is located outside the proposed construction limits of the <br />project. <br /> <br />PROPOSED UTILITY IMPROVEMENTS <br /> <br />The existing manholes, fire hydrants, gate valves, and other similar structures will be adjusted <br />and repaired as necessary as part of this project. The cost of any underground utility <br />improvements will be excluded from the assessable portion of the project and financed by the <br />appropriate utility fund. Casting replacements or repairs are considered part of the street <br />improvements and are not charged to individual utility funds. <br /> <br />Staff wi!! work with private utility companies to coordinate other utility improvements with the <br />street reconstruction project. <br /> <br />Watermain <br />Reviewing the history of watermain breaks, staff feels that there are no areas that need complete <br />replacement ofwatermain. As a general guide, watermain replacement should be considered <br />when more than five breaks occur in a ten year time period. <br /> <br />Sanitary Sewer <br />After reviewing the sanitary sewer video tapes, minimal repairs were identified. One manhole is <br />in need of rehabilitation; the bottom half of the structure shows evidence of inflow. Heavy roots <br />and several circular cracks were also noted in the pipe segments along both streets; however, <br />repairs required for these types of problems could be completed using trenchless technologies, <br />such as pipe lining. City staff will be working on a separate pipe lining project in 2008, outside <br />the scope of the PMP. <br /> <br />Based on the manhole inspections, staff has determined that the castings and rings should be <br />replaced with chimney seals to eliminate a potential source of inflow. This area has not been <br />identified as one of the City's problem areas for inflow and infiltration (1&1), therefore, these <br />costs would not be eligible for credit towards the 1&1 surcharge. However, it is important to <br />make these improvements at this time to ensure this does not become a problem area in the <br /> <br />13 <br />
