. � . <br /> � <br /> DIVIBION B - HROADWAY BEWER <br /> south BroadMay eeMer <br /> The South eroadway Sewer is that portion of the Broadway <br /> Sewer extendin downstream from a diversion st <br /> 9 ructure iust south <br /> of Decatur St, to a discharge into the box outfall at South Main <br /> Street. Dry weather plus "first flush" flow is diverted to the <br /> Sanitary District Main Interceptor immediately upstream of this <br /> section. The South Broadway Sewer thus handles only excess flow <br /> from the Broadway System except as occasional lateral connections <br /> may have been added. During dry weather, only a very nominal flow <br /> is carried in this sewer. The sewer is circular brick with a one <br /> row tile invert, 84-inches in internal diameter and approximately <br /> 1100 lineal feet in length. <br /> The 1966 investigation of this sewer resulted in the follow- <br /> ing recommendation: "Provide concrete liner (1080 '±) and install <br /> manhole near mid-point. " Although the Broadway Sewer immediately <br /> upstream has since been repaired, no major rehabilitation of this <br /> South Broadway Sewer has been accomplished to date. <br /> Current interior inspectior►s reveal no imminent signs of <br /> structural failure and the sewer qenerally has maintained its <br /> original configuration. Throughout the lfne, however` there are <br /> several instances where brick are loose or missing in the crown <br /> of the sewer and mortar joints in the crown are badly eroded to <br /> a depth of up to 2-inches. Invert tile are badly broken and <br /> numerous holes were found in the invert where tile or brick are <br /> missing. Mortar is almost completely gone from the inside row of <br /> invert brick throuqhout most of the distance. In the downstream <br /> half of this section of sewer, extensive seepage areas were noted <br /> 87023A �_� EXHIBIT E <br /> 16 of 29 <br /> R-� <br />
