摘要

The Ohio Canal Interceptor Combined Sewage Storage and Conveyance Tunnel project is onernof over 20 control measures described in the City of Akron’s Combined Sewer Overflow (CSO) Plan. Projectrnrequirements include a minimum storage volume, maximum typical year overflow frequencies for multiplernexisting and new overflow structures, gravity dewatering of the conveyance system, and ability to conveyrnboth sanitary and 10-year, 1-hour (hr) storm flows. The preliminary engineering concept included 6,136 linealrnfeet of 27-foot inside diameter (ID) tunnel, mined through rock, soil, and mixed-face conditions, and thernworld’s largest baffle drop structures. The paper discusses the City’s CSO Program as well as Planning Studies,rnPreliminary Engineering and Design, and Value Engineering for the tunnel project.
