    The Dynamic Mixed-Flow Model for Metropolitan St. Louis Sewer District
    (St. Anthony Falls Laboratory, 1979-09) Song, Charles C. S.; Leung, Kim Sau; Cardle, James A.
    The existing facilities associated with wastewater ove~flows from the Bissell watershed include wastewater collection system elements in 23 subwatersheds and flood protection facilities in 24 subsystems. Some collection system trunk sewers are over 125 years old. Portions of the existing trunk sewe~s have recently been rehabilitated as parts of pollution abatement and flood p~otection projects. Majo~ flood protection works and pollution abatement facilities were completed in the last 10 years.

    Mathematical Modeling For Cross-Irondequoit Tunnel And Associated Facility
    (St. Anthony Falls Laboratory, 1980-07) Song, Charles C. S.; Leung, Kim Sau
    The Cross-Irondequoit tunnel was originally desic;Jned as a tl:"unk sewer whose main fUnct;i.on was to convey the combineel flow to a pumping station. This system (Fig. 1-1) is located in a developing section of Rochester, New York. It is currently underutili~ed, and it is not expectep to reach cap.acity for another 50 yea:t::'s. ~he system studied consists of a 7 £t elia ... meter, 3 mile long, pO:t::'tion of the Itondequoit Creek interceptor, which ends at the Browncroft junction chamber, followed by a short 12 ft diametet section joining the junction chamber to the transition chamber and a 16 ft diameter, 6 mile long, tunnel connecting the transition chamber and the pumping station. From there the flow is pumped through pressurized conduits to a waste water treatment plant. Eventually,another tunnel will also drain into the wet well.
