26 <br />3. EXISTING CONDITIONS <br />3.1 Sanitary Sewer <br />The sanitary sewer system in the project area consists of 9 -inch diameter vitrified clay <br />pipe (VCP) which was installed in the early 1950s. The joint sealing material in use at <br />that time was typically an oakum and bituminous material which is known to deteriorate <br />and fail over time. Historically, sewer systems approaching 60 years of service have <br />been found with structural condition of the pipe varying between fair and poor, with <br />numerous offset joints, cracked segments, dips with solids deposition, and some root <br />intrusion and mineral deposits at joints. Internal inspections with a specially designed <br />television camera will be completed during final design to determine the overall <br />condition of the existing sewer. <br />The existing sanitary sewer is shown on Figure 3 in Appendix A. <br />3.2 Water Main <br />The existing water distribution mains in the project area were also installed in the early <br />1950s and consist of 6 -inch cast iron pipe (CIP). This system has had numerous breaks <br />over the past few years. Breaks will become more likely, as the pipes are approaching 60 <br />years of service. In addition, the cast iron pipes of this age are typically found to be <br />heavily corroded and potentially leaking. <br />The water main is shown on Figure S in AppendixA. <br />3.3 Storm Sewer <br />Limited storm sewer exists within the proposed project area. Stormwater along Penrod <br />Lane is directed with concrete curb and split north and south at the high point located at <br />the intersection of Penrod Lane and Wendhurst Street NE to existing facilities at 37°i <br />Street NE (Co. Rd. 93) and 36°1 Street NE. <br />Stormwater along Edgemere Street NE and Wendhurst Street NE is directed to <br />Chelmsford Lane, where the runoff flows north to the existing storm facilities at 37°i <br />Street NE (Co. Rd. 93). According to City maintenance records, the existing storm sewer <br />conveyance has historically proven to be adequate for drainage. However, the storm <br />sewer sizing and catch basin spacing does not meet current City standards. Additional <br />analysis will be completed during final design to determine the extent of storm sewer <br />required to improve drainage and prolong the life cycle of the pavement. <br />2014 STREET AND UTILITY IMPROVEMENT PROJECT <br />PEASIBILITY REPORT <br />CITY OF Sr. AN HIONY VILLAGE <br />WSB PROJECT NO. 1626-82 <br />TABLE OF CONTENTS <br />PAGE 4 <br />
